How do I know if refinance is beneficial enough to me?
When evaluating a refinance, you need to figure out the payback time. Refinancing costs money in closing costs. The payback time is the time it takes to recover the closing costs with the amount of money you are saving in interest.  For example, if the closing costs are $2,000, your payback time is 2 years if it takes 2 years to save that amount in interest with the new interest rate vs. the old one.  To estimate this, look at the difference in interest rate between your mortgage and the new one, and your mortgage balance. For example, let's say that you have $100,000 left on your mortgage, and the new rate is 1% lower than your current rate. In one year, you will save roughly $1,000 in interest. If your closing costs are $2,000, then your payback time is somewhere around 2 years. If you plan on staying in this house longer than the payback time, then it is beneficial to refinance.  There are mortgage refinance calculators online that will calculate payback time more precisely.  One thing to watch out for: when you refinance, if you expand the term of your mortgage, you might end up paying more interest over the long term, even though your rate is less and your monthly payment is less. For example, let's say you currently have 8 years left on a 15-year mortgage. If you refinance to a new 15-year mortgage, your monthly payment will go down, but if you only pay the new minimum payment for the next 15 years, you could end up paying more in interest than if you had just continued with your old mortgage for the next 8 years. To avoid this, refinance to a new mortgage with a term close to what you have left on your current mortgage. If you can't do that, continue paying whatever your current monthly payment is after you refinance, and you'll pay your new mortgage early and save on interest. It would help if we had numbers to walk you through the analysis. Current balance, rate, remaining term, and the new mortgage details.  To echo and elaborate on part of Ben's response, the most important thing is to not confuse cash flow with savings. If you have 15 years to go, and refinance to 30 years, at the rate rate, your payment drops by 1/3. Yet your rate is identical in this example.  The correct method is to take the new rate, plug it into a mortgage calculator or spreadsheet using the remaining months on the current mortgage, and see the change in payment. This savings is what you should divide into closing costs to calculate the breakeven. It's up to you whether to adjust your payments to keep the term the same after you close.  With respect to keshlam, rules of thumb often fail. There are mortgages that build the closing costs into the rate. Not the amount loaned, the rate. This means that as rates dropped, moving from 5.25% to 5% made sense even though with closing costs there were 4.5% mortgages out there. Because rates were still falling, and I finally moved to a 3.5% loan. At the time I was serial refinancing, the bank said I could return to them after a year if rates were still lower. In my opinion, we are at a bottom, and the biggest question you need to answer is whether you'll remain in the house past your own breakeven time. Last - with personal finance focusing on personal, the analysis shouldn't ignore the rest of your balance sheet. Say you are paying $1500/mo with 15 years to go. Your budget is tight enough that you've chosen not to deposit to your 401(k). (assuming you are in the US or country with pretax retirement account options) In this case, holding rates constant, a shift to 30 years frees up about $500/mo. In a matched 401(k), your $6000/yr is doubled to $12K/year.  Of course, if the money would just go in the market unmatched, members here would correctly admonish me for suggesting a dangerous game, in effect borrowing via mortgage to invest in the market. The matched funds, however are tough to argue against. The proper answer is that you run the numbers and see whether what you'll save in interest exceeds the closing costs by enough to be interesting.  Most lenders these days have calculations that can help with this on their websites and/or would be glad to help if asked. Rule of thumb: if you can reduce interest rate by 1% or more it's worth investing.
"Do you now own your new home, or are you renting?  This is a classic case of a mortgage ready to blow up. These 7/1 interest only would have a low rate, say 3%. So on $200K, the payment is $500/mo, but no principal paydown. Even if the rate were still 3% (it won't be) the 23 yr amortization means a payment of $1004 after the 7 years end. At 4%, it's $1109. 5%, $1221. I would take this all into account as you decide what to do. If you now own a new house, you should consider the morally questionable walk-away. I believe you were sold an unethical product. mb wrote ""shoot up considerably."" This is still an understatement. A product whose payment is certain to double in a fixed time is 'bad.' 'Bad' in the biblical sense. You have no obligation to keep any deal with the devil, which is exactly what you have.  There are some banks offering FHA products that might help you. I just received an offer from the bank holding a mortgage on my rental property. It's 4.5% for a refinance up to 125% of current value. There's a cost of $1800, but I owe so little, and am paying it off faster than the time left, I'm not bothering. You may benefit from such a program, but I'd still question if you can make a go of a house that even 2% underwater. Do some math, and see if you started now with a 30 year loan how the numbers work out.  (Forgive my soapbox stance on this. There are those who criticize the strategic defaulters. I think you fall into a group of innocent victims who were sold a product that was nothing less than a financial time bomb. I am very curious to know the original ""interest only"" rate, and the index/margin for the rate upon adjustment. If you include the original balance, I can tell you the exact payments based on the new rates pretty easily.)" There is another factor to consider when refinancing is the remaining term left on your loan.  If you have 20 years left, and you re-fi into another 30 year loan that extends the length that you will be paying off the house for another 10 years.  You are probably better off going with 20, or even 15.  If this is a new loan, that is less of an issue, although if you moving and buying a house in a similar price range it is still something to consider.  My goal is to have my house paid off before I retire (hopefully early semi-retirement around 55). "@Alex B already answered the first question. I want to respond to the second and third: I have heard the term ""The equity on your home is like a bank"". What does that mean? I suppose I could borrow using the equity in my home as collateral? Yes, you can borrow against the equity in your home. What you should keep in mind is that you can only borrow against the amount that you've paid on your house. For example, if you've paid $100,000 against your house, you can then borrow $100,000 (assuming the value hasn't changed). The argument that this is a good deal misses the obvious alternative: If you didn't spend that $100,000 on a house, then you'd still have it and wouldn't need to take out a loan at all. Of course, equity still has value, and you should consider it when doing the cost/benefit analysis, but make sure to compare your equity to savings you could have from renting. Are there any other general benefits that would drive me from paying $800 in rent, to owning a house? Economically: As you'll notice from my parenthetical remarks, this is extremely situational. It might be good to come up with a spreadsheet for your situation, taking all of the costs into account, and see if you end up better or worse. Also, there's nothing wrong with buying a house for non-economic reasons if that's what you want. Just make sure you're aware of the real cost before you do it." "This summer I used a loan from my 401(k) to help pay for the down payment of a new house. We planned on selling a Condo a few months later, so we only needed the loan for a short period but wanted to keep monthly payments low since we would be paying two mortgages for a few months. I also felt like the market might take a dip in the future, so I liked the idea of trying to cash out high and buy back low (spoiler alert: this didn't happen). So in July 2017 I withdrew $17,000 from my account (Technically $16,850.00 principal and $150 processing fee) at an effective 4.19% APR (4% rate and then the fee), with 240 scheduled payments of $86.00 (2 per month for 10 years). Over the lifetime of the loan the total finance charge was $3,790, but that money would be paid back into my account. I was happy with the terms, and it helped tide things over until the condo was sold a few months later. But then I decided to change jobs, and ended up having to pay back the loan ~20 weeks after it was issued (using the proceeds from the sale of the condo). During this time the market had done well, so when I paid back the funds the net difference in shares that I now owned (including shares purchased with the interest payments) was $538.25 less than today's value of the original count of shares that were sold to fund the loan. Combined with the $150 fee, the overall ""cost"" of the 20 week loan was about 4.05%. That isn't the interest rate (interest was paid back to my account balance), but the value lost due to the principal having been withdrawn. On paper, my account would be worth that much more if I hadn't withdrawn the money. Now if you extrapolate the current market return into 52 weeks, you can think of that loan having an APR ""cost"" of around 10.5% (Probably not valid for a multi year calculation, but seems accurate for a 12 month projection). Again, that is not interest paid back to the account, but instead the value lost due to the money not being in the account. Sure, the market could take a dip and I may be able to buy the shares back at a reduced cost, but that would require keeping sizable liquid assets around and trying to time the market. It also is not something you can really schedule very well, as the loan took 6 days to fund (not including another week of clarifying questions back/forth before that) and 10 day to repay (from the time I initiated the paperwork to when the check was cashed and shares repurchased). So in my experience, the true cost of the loan greatly depends on how the market does, and if you have the ability to pay back the loan it probably is worth doing so. Especially since you may be forced to do so at any time if you change jobs or your employment is terminated." If you can deal with phone calls instead of a face to face meeting, for the average person with an average refinance online tools just offer another way to shop for deals. For new mortgages, I think having a person you can meet face to face will avoid problems, but for just a simple refi, online is one of the places you should check. Compete your current mortgage company, your bank (hopefully credit union), a local broker or two and the online places. The more competition you have, the more power you have in making a good choice. Yes. Borrowing more against your home means you will pay more interest for your home. Specifically:  Does this increase the amount of interest on my home loan by $144.56 per month to start with? Yes, that is exactly what it means. As to whether or not that is a good use of the money, I can't say. You're making various assumptions here... They could be accurate or, if this is your first rental home, they could be wildly optimistic (100% occupancy rate? that won't last). Additionally, houses are physical goods which depreciate. Put another way, they fall apart, and you (as the owner) are responsible for fixing it. You have the basic idea right, I just think you should plan for a worst-case scenario, and it looks like you're planning for the best. You don't say what the time remaining on the current mortgage is, nor the expense of the refi.  There are a number of traps when doing the math. Say you have 10 years left on a 6% mortgage, $200K balance. I offer you a 4% 30 year. No cost at all. A good-intentioned person would do some math as follows: Please look at this carefully. 6% vs 4%. But you're out of pocket far more on the 4% loan. ?? Which is better? The problem is that the comparison isn't apples to apples. What did I do? I took the remaining term and new rate. You see, so long as there are no prepayment penalties, this is the math to calculate the savings. Here, about $195/mo. That $195/mo is how you judge if the cost is worth it or the break-even time. $2000? Well, 10 months, then you are ahead.  If you disclose the time remaining, I am happy to edit the answer to reflect your numbers, I'm just sharing the correct process for analysis.  Disclosure - I recently did my last (?) refi to a 15yr fixed 3.5%. The bank let the HELOC stay. It's 2.5%, and rarely used. "The usual rule of thumb is that you should start considering refinance when you can lower the effective interest rate by 1% or more. If you're now paying 4.7% this would mean you should be looking for loans at 3.7% or better to find something that's really worth considering. One exception is if the bank is willing to do an ""in-place refinance"", with no closing costs and no points. Sometimes banks will offer this as a way of retaining customers who would otherwise be tempted to refinance elsewhere. You should still shop around before accepting this kind of offer, to make sure it really is your best option. Most banks offer calculators on their websites that will let you compare your current mortgage to a hypothetical new one. Feed the numbers in, and it can tell you what the difference in payment size will be, how long you need to keep the house before the savings have paid for the closing costs, and what the actual savings will be if you sell the house in any given year (or total savings if you don't sell until after the mortgage is paid off). Remember that In addition to closing costs there are amortization effects. In the early stages of a standard mortgage your money is mostly paying interest; the amount paying down the principal increases over the life of the loan. That's another of the reasons you need to run the calculator; refinancing resets that clock." Purchase loans tend to be more challenging to get the best possible rate, because you have to balance closing the loan and getting the contract. So there isn't as much time to shop around as when you do a refinance.  I disagree with the sentiment to go with your local bank. Nothing wrong with asking at your local bank and using their numbers as a baseline, but chances are they won't be competitive. There are many reputable online mortgage originators that will show accurate fees and rates upfront assuming you provide accurate information.  In the past there were a lot of issue with Good Faith Estimates being pretty much worthless. There were a fair number of horror stories about people showing up to closing and finding out fee or rates had increased dramatically. There was a law passed after the housing debacle that severely limits the shenanigans that lenders can do at closing and so there is less risk when going with a lesser known lender. In fact I would say the only real risk with a lender now days is choosing one that happens to be overloaded and or just has poor customer service in general. Personally I have found the most competitive rates from Zillow's mortgage service and the now defunct Google mortgage. The lenders tend to be smaller, but highly efficient. They are very much dependent on their online reputations. I have heard good things about a number of larger online lenders, but I don't have personal experience so I will leave them off. I personally wouldn't worry much about whether the loan is sold or not. Outside of refinancing I don't think I have ever talked to the bank servicing my mortgage about my mortgage. There just isn't much need to talk to them. "Your Spidey senses are good. A good friend would not put you in such a position. It's simple, to skirt some issue (we'll get to that in a second) you are being asked to lie. All for a 15% return on your $$$$. <<< How much is that?  You can easily lend him the money, and have a better paper trail. But the bank is not going to like that, and requires this money from friends or family to be a gift. I've heard mortgage guys at the bank say ""It's just a formality, we need this paperwork to sell the loan to the investors."" These bankers belong in jail, or at least fired and barred from the industry. They broke the economy in 2008, and should be stopped from doing it again." With an annual income of $120,000 you can be approved for a $2800 monthly payment on your mortgage. The trickier problem is that you will save quite a bit on that mortgage payment if you can avoid PMI, which means that you should be targeting a 20% down-payment on your next purchase. With a $500,000 budget for a new home, that means you should put $100,000 down. You only have $75,000 saved, so you can either wait until you save another $25,000, or you can refinance your current property for $95k+ $25k = $120k which would give you about a $575 monthly payment (at 30 years at 4%) on your current property. Your new property should be a little over $1,900 per month if you finance $400,000 of it. Those figures do not include property tax or home owners insurance escrow payments. Are you prepared to have about $2,500 in mortgage payments should your renters stop paying or you can't find renters?  Those numbers also do not include an emergency fund. You may want to wait even longer before making this move so that you can save enough to still have an emergency fund (worth 6 months of your new higher expenses including the higher mortgage payment on the new house.) I don't know enough about the rest of your expenses, but I think it's likely that if you're willing to borrow a little more refinancing your current place that you can probably make the numbers work to purchase a new home now. If I were you, I would not count on rental money when running the numbers to be sure it will work. I would probably also wait until I had saved $100,000 outright for the down-payment on the new place instead of refinancing the current place, but that's just a reflection of my more conservative approach to finances. You may have a larger appetite for risk, and that's fine, then rental income will probably help you pay down any money you borrow in the refinancing to make this all worth it. It may be possible to get more cash than you currently have. For example, If you have $200,000, you could buy a distressed property for $150,000, spend $50,000 on renovations, get it appraised for $300,000 and then cash out refi $240,000 (keeping 20% equity to avoid MIPs) to invest. This would be analogous to flipping a house for yourself. Normally flippers buy a house for cheap, then sell it to someone else for way more than their total outlay in purchase + improvements. The only difference here is there's no 3rd party - you stay in the house and essentially buy it from yourself with the mortgage. The reason for borrowing instead of paying cash for major renovations should be the same for the decision about whether to borrow or pay cash for the home itself.  Over history, borrowing using low, tax-deductible interest while increasing your retirement contributions has always yielded higher returns than paying off mortgage principal over the long term. You should first determine how much you need to save for retirement, factor that into your budget, then borrow as much as needed (and can afford) to live at whatever level of home you decide is important to you.  Using this same logic, if interest rates are low enough, it would behoove you to refinance with cash out leveraging the cash to use as additional retirement savings. It depends on how long it will take you to pay off the personal loan, the rate for the personal loan, the refi rate you think you can get, how much principal you will have to add to get the refi (may have gone up since then). Since you did not provide all the necessary details, the general answer is to sketch out your total payments (mortgage + personal loan) with and without the refi over the life of the mortgage and see if you end up with more money in your pocket with the refi. My overall impression based on the details you did provide is that you will probably find it worthwhile to do the refi. Streamline refinance is the way to go.  You don't have to stay with the same bank to do so either.  The big advantage of the streamline is the original appraisal is used for the refinance, so as long as you didn't have negative amortization(impossible in FHA anyways), you're good to go.  It will be much less paperwork and looser credit standards.  The ONLY downside is that upfront and monthly FHA mortgage insurance ticked up from where it was 2 years ago.  If you're under a 80% LTV however you won't have to worry about it.
