How much house can I afford, waiting around 3 years or so
On $4K/mo gross about $1000/mo can go to the mortgage, and at today's rates, that's about $200K of mortgage the bank might lend you.  Income is qualified based on gross, not net, so if $48,000/yr is wrong, please scale my guesstimate down a bit. In the end, today's rates allow a mortgage of nearly 4X one's gross income. This is too high, in my opinion. I'm answering what the bank would approve you at, not what I think is wise. Wise, in my opinion is 2.5-3X one's income, tops.
The $3K includes property tax, right? It looks like the mortgage alone will be about $2150 or so. If your (cal) state tax is enough to put you into itemized deductions, your mortgage and property tax are a write off, and the $3k will actually be closer to the $2K you are considering for rent.  The wild card as I see it is that your budget is so tight that any unforeseen expenses will be charged. As a long time homeowner, I know these expenses sometime appear to be high, and regular, despite their random nature. The money earmarked for credit card payments will go a long way to cover the tight budget you seem to have. This and your decreasing support makes this look tight but not impossible. The condition of the house would make or break the deal, in my opinion. "A bank may not like loaning money to you for this. That is one snag. You listed 500,000-600,000$ for a monster of a house (3000 sqft is over three times the average size of homes a hundred years ago). Add in the price of the land at 60K (600K divided ten ways). Where I live, there is a 15% VAT tax on new homes. I can't find out if California imposes a VAT tax on new homes. Anyway, returning back to the topic, because of the risk of loaning you 660K for a piece of land and construction, the bank may only let you borrow half or less of the final expected cost (not value). Another huge snag is that you say in a comment to quid ""I came up with this conclusion after talking to someone who had his property built in early 2000s in bay area for that average price"". Let's apply 3% inflation over 15 years to that number of 200$/sqft. That brings the range for construction costs to 780K-930K. Even at 2% inflation 670K-810K. Edit: OP later expanded the question making it an inquiry on why people don't collaborate to buy a plot of land and build their homes. ""Back in the day"" this wasn't all that atypical! For example, my pastor's parents did just this when he was a young lad. Apart from the individual issues mentioned above, there are sociological challenges that arrive. Examples: These are the easy questions." Should I seek a house on limited income? No. my income in intermittent Lenders want consistent income.  And a down payment. a little over 10 grand a year That's less than $1,000/month.  (I won't even ask whether or not it's after taxes.) https://www.investopedia.com/terms/d/dti.asp A debt-to-income ratio smaller than 36%, however, is preferable, with no more than 28% of that debt going towards servicing a mortgage.  Thus, you could hypothetically afford a $300 mortgage payment, which means -- ignoring mortgage insurance -- you can afford a $27,000 house. If you expect a significant increase in future income, then you should wait until that future income is assured, and then buy based on that decision. Buying more house than you can afford is what caused you to have to sell; you don't want to do that again. Instead of buying more house now, buy the right house for what you have now.   Better yet, though, you might rent instead of buying until the future income comes onboard.  Then you can get the best of both worlds - you get to buy the house you can afford in a year or two, but also don't overspend your income. If you are still paying off debt, then you should have about $1000 in savings and put all you can towards non-mortgage debt. If you don't have any debt besides your mortgage, then add up all of your monthly expenses including food, gas, utilities and keep 3-6 months in liquid savings. Whether you keep 3 or 6 months depends on how safe your income is. If you have a steady safe job, you might be safe with 3 months. But, if your employer is cutting back or you are in a commission based job or self employed - then lean more towards 6 months expenses. Congrats on your new home! The monthly payment difference isn't that great On a $300K loan, the 30 year monthly payment (at 4%) is $1432, the 15 year (at 3.5%) is $2145, that $712 per month, or 50% higher payment. $712 is the total utility or food bill for a couple. If that $1432 represents 25% of income (a reasonable number) then $2145 is over 35%. I'd rather use that money for something else and not obligate myself at the start of the mortgage.  Given how little we save as a country, the $712 is best put into a matched 401(k) in the US or other retirement account if elsewhere. "I recently moved out from my parents place, after having built up sufficient funds, and gone through these questions myself. I live near Louisville, KY which has a significant effect on my income, cost of living, and cost of housing. Factor that into your decisions. To answer your questions in order: When do I know that I'm financially stable to move out? When you have enough money set aside for all projected expenses for 3-6 months and an emergency fund of 4-10K, depending on how large a safety net you want or need. Note that part of the reason for the emergency fund is as a buffer for the things you won't realize you need until you move out, such as pots or chairs. It also covers things being more expensive than anticipated. Should I wait until both my emergency fund is at least 6 months of pay   and my loans in my parents' names is paid off (to free up money)? 6 months of pay is not a good measuring stick. Use months of expenses instead. In general, student loans are a small enough cost per month that you just need to factor them into your costs. When should I factor in the newer car investment? How much should I   have set aside for the car? Do the car while you are living at home. This allows you to put more than the minimum payment down each month, and you can get ahead. That looks good on your credit, and allows refinancing later for a lower minimum payment when you move out. Finally, it gives you a ""sense"" of the monthly cost while you still have leeway to adjust things.  Depending on new/used status of the car, set aside around 3-5K for a down payment. That gives you a decent rate, without too much haggling trouble. Should I get an apartment for a couple years before looking for my own   house? Not unless you want the flexibility of an apartment. In general, living at home is cheaper. If you intend to eventually buy property in the same area, an apartment is throwing money away. If you want to move every few years, an apartment can, depending on the lease, give you that. How much should I set aside for either investment (apartment vs   house)? 10-20K for a down payment, if you live around Louisville, KY. Be very choosy about the price of your house and this gives you the best of everything. The biggest mistake you can make is trying to get into a place too ""early"". Banks pay attention to the down payment for a good reason. It indicates commitment, care, and an ability to go the distance. In general, a mortgage is 30 years. You won't pay it off for a long time, so plan for that. Is there anything else I should be doing/taking advantage of with my   money during this ""living at home"" period before I finally leave the   nest? If there is something you want, now's the time to get it. You can make snap purchases on furniture/motorcycles/games and not hurt yourself. Take vacations, since there is room in the budget. If you've thought about moving to a different state for work, travel there for a weekend/week and see if you even like the place. Look for deals on things you'll need when you move out. Utensils, towels, brooms, furniture, and so forth can be bought cheaply, and you can get quality, but it takes time to find these deals. Pick up activities with monthly expenses. Boxing, dancing, gym memberships, hackerspaces and so forth become much more difficult to fit into the budget later. They also give you a better credit rating for a recurring expense, and allow you to get a ""feel"" for how things like a monthly utility bill will work. Finally, get involved in various investments. A 401k is only the start, so look at penny stocks, indexed funds, ETFs or other things to diversify with. Check out local businesses, or start something on the side. Experiment, and have fun." I am answering this in light of the OP mentioning the desire to buy a house.  A proper mortgage uses debt to income ratios. Typically 28/36 which means 28% of monthly gross can go toward PITI (principal, interest, tax, insurance) and the total debt can go as high as 36% including credit cards and car payment etc. So, if you earn $5000/mo (for easy math) the 8% gap (between 28 and 36) is $400. If you have zero debt, they don't let you use it for the mortgage, it's just ignored. So a low interest long term student loan should not be accelerated if you are planning to buy a house, better put that money to the down payment. But for credit cards, the $400/mo carries $8000 (banks treat it as though the payment is 5% of debt owed). So, I'd attack that debt with a vengeance.  No eating out, no movies, beer, etc. Pay it off as if your life depended on it, and you'll be happier in the long run. No. As long as you live in the house for 3 years, it's yours to keep. Financing has nothing to do with that. If you don't think you're necessarily going to stay in this area for five years, consider another option: renting. Five years is often quoted as the minimum length of time for buying (over renting), as the costs of the house purchase and the mortgage are significant - and if you're buying a new house every 5 years you're putting several thousand dollars of fees up front each time.  If you don't assume that house prices will increase (as they won't necessarily), then you can consider these costs - say, $5000-$6000 for a $500k house - an extra 1% or so of interest that first year.  If you are there 5 years, then you're paying 0.2% extra (more or less); that's reasonable, but if you're there only 2 years, you're adding 0.5% to your rate, which is pretty significant. You won't necessarily come out ahead here (versus renting). Renting for a year or two gives you enough time to find out if you do like the area, and if you do, you buy then - with more knowledge of the area and a chance to make a purchase at the right time for you. You pay off your loans, or at least a chunk of them, now, save some of the rest, and then rethink in a couple of years.  If you then don't qualify for a doctor's mortgage anymore, you just save up the rest of the 20% before making the purchase. A fourteen-year-old can invest a few thousand into commuting to a part-time job or an education. If you can wait five years for a couple hundred you can wait two to four years for a car (or gas money) or a class (or some textbooks.) "If I were you, I would rent.  Wait to buy a home.  Here is why: When you say that renting is equal in cost to a 30-year mortgage, you are failing to consider several aspects.  See this recent answer for a list of things that need to be considered when comparing buying and renting. You have no down payment.  Between the two of you, you have $14,000, but this money is needed for both your emergency fund and your fiancée's schooling. In your words: ""we can’t reeaallllly afford a home.""  A home is a big financial commitment.  If you buy a home before you are financially ready, it will be continuous trouble.   If you need a cosigner, you aren't ready to buy a home.  I would absolutely advise whoever you are thinking about cosigning for you not to do so.  It puts them legally on the hook for a house that you can't yet afford. You aren't married yet.  You should never buy something as big as a home with someone you aren't married to; there are just too many things that can go wrong.  (See comments for more explanation.)  Wait until you are married before you buy. Your income is low right now.  And that is okay for now; you've been able to avoid the credit card debt that so many people fall into. However, you do have student loans to pay, and taking on a huge new debt right now would be potentially disastrous for you.  Your family income will eventually increase when your fiancée gets her degree and gets a job, and at that time, you will be in a much better situation to consider buying a house. You need to move ""ASAP."" Buying a house when you are in a hurry is a generally a bad idea. When you look for a home, you need to take some time looking so you aren't rushed into a bad deal that you will regret. Even if you decide you want to buy, you should first find a place to rent; then you can take your time finding the right house.  To answer your question about escrow: When you own a house, two of the required expenses that you will have besides the mortgage payment are property taxes and homeowner's insurance.  These are large payments that are only due once a year.  The bank holding the mortgage wants to make sure that they get paid.  So to help you budget for these expenses and to ensure that these expenses are paid, the bank will add these to your monthly mortgage payment, and set them aside in a savings account (called an escrow account).  Then when these bills come due once a year, they are paid for out of the escrow account." "I'll start by focussing on the numbers. I highly recommend you get comfortable with spreadsheets to do these calculations on your own.  I assume a $200K loan, the mortgage for a $250K house. Scale this up or down as appropriate. For the rate, I used the current US average for the 30 and 15 year fixed loans. You can see 2 things. First, even with that lower rate to go 15 years, the payment required is 51% higher than with the 30. I'll get back to that. Second, to pay the 30 at 15 years, you'd need an extra $73. Because now you are paying at a 15 year pace, but with a 30 year rate. This is $876/yr to keep that flexibility. These are the numbers.  There are 2 camps in viewing the longer term debt. There are those who view debt as evil, the $900/mo payment would keep them up at night until it's gone, and they would prefer to have zero debt regardless of the lifestyle choices they'd need to make or the alternative uses of that money. To them, it's not your house as long as you have a mortgage. (But they're ok with the local tax assessor having a statutory lien and his hand out every quarter.) The flip side are those who will say this is the cheapest money you'll ever see, and you should have as large a mortgage as you can, for as long as you can. Treat the interest like rent, and invest your money.  My own view is more in the middle. Look at your situation. I'd prioritize  In my opinion, it makes little sense to focus on the mortgage unless and until the first 5 items above are in place. The extra $459 to go to 15? If it's not stealing from those other items or making your cash flow tight, go for it.  Keep one subtle point in mind, risk is like matter and energy, it's not created or destroyed but just moved around. Those who offer the cliche ""debt creates risk"" are correct, but the risk is not yours, it's the lender's. Looking at your own finances, liquidity is important. You can take the 15 year mortgage, and 10 years in, lose your job. The bank still wants its payments every month. Even if you had no mortgage, the tax collector is still there. To keep your risk low, you want a safety net that will cover you between jobs, illness, new babies being born, etc.  I've gone head to head with people insisting on prioritizing the mortgage payoff ahead of the matched 401(k) deposit. Funny, they'd prefer to owe $75K less, while that $75K could have been deposited pretax (so $100K, for those in the 25% bracket) and matched, to $200K. Don't make that mistake." If you can't afford it don't buy it, the next perfect house is just around the corner. The more time you spend researching and looking at houses, the increased chance you will find the perfect house you can afford. Also, here in Australia, we (the banks as well) factor in an interest rate rise of 2% above current rates to see if repayments can still be afforded at this increased rate. A $250K earner might have $4M in retirement savings and $500K in available funds, but doesn't wish to spend all his liquidity on the house. In general, a house might cost 2-3 times one's annual income. It would take many years to get that saved up. They might want to have the house sooner.  It all goes back to choice, priorities, personal preference.
