They were both off by a large amount.So, can you tell me what a house will sell for 6 months from now when you finish the rehab and put the house on the market? 

This is the issue many have with wholesalers, what you are doing is marketing the property to the masses which requires a license (the I am marketing the contract I would love to see how a court would view that).

My real estate agent brought it to me as an off market deal.

And, as it relates to your plan, you probably know the optics of your market better than I, but I find that five unit properties are often slightly less desirable than four unit properties, simply because buyers can no longer use conventional financing for five units.

I am in a beach market (Gulf Coast FL) and a house 1 mile and a house 5 miles away from the beach may be 50%.  

Took this over from original owners at severe under market rents.

My market isn't too far from you.

Love to share anything I've learned about the market and in my current portfolio. 

It's an odd market right now.

I am also extremely interested in getting into the market there in Sandbridge myself.
