Peer to peer lending business model (i.e. Lending Club)
This is all answered in the prospectus. The money not yet invested (available/committed to a note but not yet funded) is held in pooled trust account insured by FDIC. Money funded is delivered to the borrower. Lending Club service their notes themselves. Read also my reviews on Lending Club. The best description of P2P lending process I saw comes from the SEC proceedings. They are very careful about naming things that are happening in the process. Prosper got back to business after this order, but the paper describes succinctly how Prosper worked when its notes haven't yet been registered by the SEC. These materials contain a lot of responsible comments on how crowdfunding, including P2P lending, works.
"Here's a blog by a guy who is trying to do this: Personal Loan Portfolio And here's another one: bobharris.com Do a quick search for ""prosper loan"" or ""kiva"" on blog search." "There is no one solution to every project finance problem. Two models might make sense in this situation, however. In this case, you would count all the money that you give to your friend as a loan which he will pay back with interest. The interest rate and loan amounts will have to be agreed on by both of you. One one hand, the interest should be high enough to reward you in a successful outcome for the amount of risk that you take on if things don't work out. On the other, the interest rate needs to be low enough where his earnings after loan repayment justify your friend's effort, in addition to being competitive to ant rate your friend could secure from a bank. The downside to this plan is you don't directly benefit from the franchise's profits. In this model, you will record the cash that each of you invests. Since your friend is also adding ""sweat equity"" by setting up and operating the franchise, you will need to quantify the work that your friend and you invest into the franchise. Then you can determine how much each of you has invested in terms of dollars and split any franchise profits based on those proportions. The downside of this plan is that it is difficult to estimate how much time each of you invests and how much that time is worth." This is fraud and could lead to jail time. The vast majority of people cannot obtain such loans without collateral and one would have to have a healthy income and good credit to obtain that kind of loan to purchase something secured by a valuable asset, such as a home. Has this been done before?  Yes, despite it being the US, you may find this article interesting.     Hopefully, you see how the intent of this hypothetical situation is stealing. The model itself is fairly common for serving particular niche markets. A few other organizations which operate in similar setups: prepaid card providers such as NetSpend, GreenDot, AccountNow, etc; startups such as SmartyPig, PerkStreet, WePay, and HigherOne. Still, nobody else seems to be providing full-service online banking to mainstream customers the way we plan to.  We plan to have much better security than most banks, which isn't hard given the current sorry state of online banking in the US. And having an intermediary who's looking out for your interests can be a good thing. David, my co-founder Josh lays out our launch plans and why we are invite-only in his latest post. In short, we made a decision to build our own call center rather than outsource it, and that limits how quickly we can bring people on. For questions 1 and 2.  1) If you are packing the loans into a CDO, they are being sold on the open market. Once it achieves a AAA rating, as most did even though they were mostly subprime, alt a, or arm, it is sold and shipped off the originator's books (While the originator of the CDO collects X% in fees)  Basically how the originator makes their money is by X amount of CDOs they sell. There was no incentive to pick and choose the best borrowers to sell a loan to because how the CDOs were sold they achieved the best rating regardless of the borrowers credit risk.  Due to this model, people are going to try and get as many people into the homes and sell the CDO asap. This caused questionable lending practices to result, NINJA (no income, no job, no assets) loans, manipulating borrowers income, assets, etc.   Things that could be changed to help not have this occur again:  a) Feds monetary policy was pretty meh during this period, due to low interest rates the banks had pretty much an endless supply of money and when all the reasonable ventures dried up they had to explore other opportunities to lend.  b) Ratings agencies need an overhaul in how they receive their commission, preferably they should be being paid by the investor not the person issuing the security. This will help to eliminate the bias that results.  c) Having X% (2-5) remain on the institutions books who created the CDO will help to make them responsibly lend. This is because if they are required to have it remain on their books, they will make better longer term decisions in who to lend to.  I'm pretty sure all of these issues are discussed in Nouriel Roubini's book [Crisis Economics](http://www.amazon.com/Crisis-Economics-Course-Future-Finance/dp/1594202508)  Another Great book already mentioned in this thread is by Michael Lewis [The Big Short](http://www.amazon.com/Big-Short-Inside-Doomsday-Machine/dp/0393338827/ref=sr_1_1?s=books&amp;ie=UTF8&amp;qid=1324140607&amp;sr=1-1)  If your interested in the European Crisis Michael Lewis also just came out with [Boomerang](http://www.amazon.com/Boomerang-Travels-New-Third-World/dp/0393081818/ref=sr_1_1?s=books&amp;ie=UTF8&amp;qid=1324140665&amp;sr=1-1) Swimming clubs exist.   Treat it as a start up business and it's easier to figure out.   Once you know about what people are willing to pay to join you know about how much you can spend.   Our family business invites tenants to use a private pool located at one of our properties. We maintain the facility and have appropriate signs posted and a balloon insurance policy specifically for the pool. In 1975 the pool cost 25,000 to install and we spend about $5000-$6000 to operate and heat it each season.   The downside is that there is likely a lot less support for the idea than you think. You're going to have to limit access to it with a membership and that's going to be a pain to figure out because it will almost certainly require an employee or a very expensive electronic access control.  You can't really open it up to the entire community without some sort of contract or no one has an incentive to pay. Every time a home sells in the community you either lose a customer or gain a headache if you don't have some sort of deed restriction or membership fee. "I have a friend who had went on a seminar with FortuneBuilders (the company that has Than Merrill as CEO). He told me that one of the things taught in that seminar was how to find funding for the property that you want to flip. One of the things he mentioned was that there are so-called ""hard money"" lenders who are willing to lend you the money for the property in exchange for getting their name on the property title. Last time I checked it looked like here in Florida we had at least Bridgewell Capital and Fairview Commercial Lending that were in that business. These hard money lenders get their investment back when the house is sold. So there is some underlying expectation that the house can be sold with some profit (to reimburse both the lender and you for your work). That friend of mine did tell me that he had flipped a house once but that he did not receive the funding to that from a lender but from an in-law, however it was through a similar arrangement." P2P lending is basically a debt product with (much) higher risk, I doubt that there's any regulation or government backing in it. The money lent to borrowers are not collateralized or securitized. To what end would you want to break the law? Why would you think it is beneficial to you in any way? The reason for these limitations is to protect people who have no financial reserves and are not sophisticated investors from making dangerous and risky investments with the little money they have to invest. You need to remember that there's no guarantee of principal with these loans and the rate of default is pretty high. From my own personal experience with Lending Club (and I've only invested in A and some B-rated loans) - rate of default is about 10%. This may be a nice exercise in microlending - but if you want to put all your savings into this, you're taking a huge risk. Risk which is completely unjustified since not only the returns are pretty low (again - from my aforementioned experience: <6% APR, you take higher rate loans - you get higher rate of defaults), but they're also taxed as ordinary gains. Why would you not, instead, invest in a more conservative bond or bond/stock mix fund which will pay you dividends that will get preferential tax treatment and appreciation would be subject to capital gains tax? No reason. And the limitation on who can invest in Lending Club is there for exactly this purpose - to weed out people like you who have no idea of what they're doing. I don't know much about paypal or bitcoin, but I can provide a little information on BTC(Paypal I thought was just a service for moving real currency).  BTC has an exchange, in which the price of a bitcoin goes up and down. You can invest in to it much like you would invest in the stock market. You can also invest in equipment to mine bitcoins, if you feel like that is worthwhile. It takes quite a bit of research and quite a bit of knowledge. If you are looking to provide loans with interest, I would look into P2P lending. Depending on where you live, you can buy portions of loans, and receive monthly payments with the similiar risk that credit card companies take on(Unsecured debt that can be cleared in bankruptcy). I've thrown a small investment into P2P lending and it has had average returns, although I don't feel like my investment strategy was optimal(took on too many high risk notes, a large portion of which defaulted). I've been doing it for about 8 months, and I've seen an APY of roughly 9%, which again I think is sub-optimal. I think with better investment strategy you could see closer to 12-15%, which could swing heavily with economic downturn. It's hard to say. For people who are good with money (presumably), Kiva.org gives your money to such people who apply for loans through social service organizations in various countries (I believe this is how it's done). The people state what they will use the money for. It can be as simple as 'buying provisions for food truck business' or 'replacing wheels on tractor.' Then they pay the money back and you (who donated x number of dollars) use that repaid money to make another loan. "You are confining the way you and the other co-founders are paid for guaranteeing the loan to capital shares. Trying to determine payments by equity distribution is hard. It is a practice that many small companies particularly the ones in their initial stage fall into. I always advise against trying to make payments with equity, weather it is for unpaid salary or for guaranteeing a loan such as your case. Instead of thinking about a super sophisticated algorithm to distribute the new shares between the cofounders and the new investors, given a set of constraints, which will most probably fail to make the satisfactory split, you should simply view the co-founders as debt lenders for the company and the shareholders as a capital contributor.  If the co-founders are treated as debt lenders, it will be much easier to determine the risk compensation for guaranteeing the loan because it is now assessed in monetary units and this compensation is equal to the risk premium you see fit ""taking into consideration the probability of default "". On the other hand, capital contributors will gain capital shares as a percentage of the total value of the company after adding SBA loan." See my post listing Trumps failures.  Clearly lenders/investors/people get sucked into things all the time.  P.S. Established Corps and LLC are granted credit all the time.  In my example I never mentioned how old or established, or well funded any of these Corps were. Yes and no, P2P Capital Markets is similar concept but is more geared towards business loans. Community Lend used to offer this service but has stopped. A real life experience. A friend of mine did that with his housemates. They bought a house together as students and it worked for them. The tricky bit is to have a very good contract with your housemates as to how the venture should work.  What if? Somebody can't pay, somebody can't enjoy the house (on an extended trip), somebody wants out (marriage, etc.) It worked for my friend...
