That depends what your game plan is. Would you like to buy and sell within a month? Buy hold sell? or buy and never sell?
You can do
-conventional bank financing (and your credit score and debt to income ratio will matter)
-a partnership (those things don't matter)
-hard money (asset based lending, no credit necessary but a double digit interest rate.)
-or seller financing.
I have heard of people buying a home with no down, 0% interest, & terrible credit because they found someone willing to sell a property with 100% seller financing and the property seller was just able to make that kind of a financial decision. They aren't everywhere but they're out there!
But if you want to increase your success rate, then offer more appealing terms like a better down payment and interest rate. If you create the note right, I may be able to buy it from the proeperty seller which will increase your chances of find a GREAT deal. -Because some say: "I want cash, I don't want monthly payments" and since I buy well created promissory notes then you can tell them they are able to sell it to me!
And if they get 10% down, a 9% interest rate, a 30 amortization, a 7 year balloon, and you have 650+ credit score then they can expect top dollar for selling their promissory note, other wise the note gets discounted more. Those aren't minimum requirements, just what is getting top dollar in today's secondary market.
