If you find you are unable to raise the money for an all-cash purchase, switching gears to Fannie will only work if you have a LONG time to close in your PSA or have many extension options (which usually require more hard earnest money.)

I fund their deals 100% they make money I charge nothing up front I only make money when they make money we get paid the same day off of the HUDs..

We're in the business to make money right?

I figured why not just use a banks money instead of using a customers money and not have to deal with picky customers.

Quote from @Enrique Toledo: I came across a really good seller financing deal and I would like to purchase it as my first deal but I don’t have enough money for the down payment.can I use a lender of some sort to give me money for the down payment?

Does anyone know of a dscr lender that will allow for seasoned money for a down payment and a really good property manager in Ohio specifically in Columbus, Cin, and Cleveland?  

Look for some of those to go in as an LP (limited partner) and learn and grow your knowledge, skills and investment money so you'll be ready for the next accredited deal. 

Will this be a good investment time and money wise?

I would rather do this and retain my money then give it to the bank as interest. 

For the most part, most lenders are going to be relatively close in cost assuming we are talking about a straight forward loan product, we all borrower from the same pool of money to make these loans.
