@Anna Ahhee - I read your plan. And honestly, there's still some parts of it that I still don't understand. But the base of it seems to be a basic lease-option plan. I've been doing that for years. Many investors have been. And when I first started offering my properties with lease-option, I also considered it as a way to help people (like you alluded to in your original post). And the cold, hard, truth of the matter is that most lease-option buyers will never be able to actually get a bank loan and complete the process. Maybe with a LOT of hand-holding. And, like I tried to explain in an earlier post, there's a lot of these same people who will burn you, even though you have given them a great opportunity and tried to help them.
Now, I'm still a little confused about your role in all of this. It seems that you may be taking on the role of matching up a seller who is willing to sell with lease-option, to a buyer who is wanting to buy with lease-option. That would be called real estate brokerage and most states require a broker's license for that (a.k.a. "agent" and/or "Realtor").
On the other hand, there may be ways to do this without doing brokerage. There are investors who basically flip option contracts, or who do sandwich lease-options. There's one guy who has a system called "sub3" that is doing something similar to this. And there are lots of investors who buy with owner-financing (either lease-option, land-contract, wrapped mortgage, or sub2) and then sell with owner-financing or lease-option.
I'm afraid that you don't appear to have anything new, unique, or novel, but the good news is that your basic plan (or something similar) is a sound strategy, so long as you remember that the actual cash-out rate, where the lease-option buyer actually gets a bank loan to complete the process, is low. And these same people who are "buyers" instead of renters are still quite capable of leaving a house in a total mess with thousands of dollars worth of damage and missed payments. It's typically better than having renters, but not the prize jewel of investing that it may seem. Check into a book called, "Buy Low, Rent Smart, Sell High".
Anyway, I'm not intending to burst your bubble or to throw water on your fire. But I'm not sure where the "helping people" part is or the "open-minded" part of your plan is. Now, if you can work with tenant-buyers to help them pay on time, improve their credit, and get a bank loan within 2 or 3 years to complete the process, then you are adding real value, and I would gladly pay you for that service.
I hope that I have not offended you again, and I may still be missing something in your plan.
