The learning curve for flips is high and I have seen a lot of newbies lose money on flips mostly because they don't know how to figure out he After Repair Value and accurately estimate the construction costs.

You also have the option of using sites like Zillow and Trulia to see what they "estimate" the rent is in the area... however those sites are not terribly accurate, and they should be used just to ballpark a number. 

I have found that to be accurate, just when I think I have found the greatest deal of my career another comes through.

@Nikki Harmon, I tend to agree with Ken T. when he said "he obviously didn't get a good price for your home if he had to have 6 people come look at it", but not about the part where he said "so yay for you", that is, if you were accurate with us about giving him a sizeable discount because of your need(?)

Accurate rehab estimates and hiring contractors2.

Sounds pretty accurate.

Darryl,  Sorry, here are more accurate numbers.  

Does that sound accurate? 

They really don't have much to audit so the standard mid-size firm requirements that drive costs to $25k+ aren't really accurate any more.  

They will be back out tomorrow to more accurately diagnosis the problem.
