I have NEVER seen a pro forma statement put together by a seller or broker that 1.

Study the market.

While we are not immune to market shifts, we typically don't see huge bubble bursts. 

Have you considered creative financing options like joint ventures or seller financing to reduce reliance on outside capital?

With that, if I were the seller, I'd ask for a little more than the current market value of the land.

Purchase price: $15,000 Cash invested: $25,000 Sub to deal - paid the seller and wholesaler $15,000 + $7500 closing costs to assume $84,000 mortgage with a monthly PITI of $575.

I suspect it's due to the change in the housing market and economy.  

The only other option would be to get a coborrower to bring the down payment or get seller financing with a lower down payment. 

Of course, that opens up a whole new can of worms RE the tax implications of having the in-laws live at below-market rents in one of our properties.  

But after working with him, I realized he was very systematic and mostly cared about closing deals without much care for the client's long term needs.Here’s an example: I had a $10K escrow with the seller—$5K due upfront and $5K after the inspection.
