How do you project FMV after a rehab?

[Brian Caulfield]

Newbie here trying to learn as much as I can.

How do you project what your FMV will be after a rehab/renovation?

Example, say a property is on the market for $100k. You look at it and estimate repairs to be $50k but you know after this it will be worth $200k. Obviously you can compare to the near by market to estimate, but can you get to a more accurate number? And if so, how do you get an accurate number?
