Most underwriters and lenders have their own set of rules but generally they all agree with each other.

but a lot goes into analyzing a deal, including: $/SF, Average Days on Market in the area, how easy or difficult it is to get permits in the area, how long the flip would take, comps/ARV, Rehab, Rental Rates, how the area is trending, holding/carrying/hard money costs, closing/commission costs etc.If you can analyze the deal, you can then negotiate the deal with sellers, buyers, and lenders.
