Is your rehab budget enough/accurate?

Too often I read posts where it explicitly states that Appreciation is a gamble.

not being in my main USA market, I still will only invest there with extra, non core money.3- Indiana Jones type adventurers/thrill seekers- like my friend who brought in Baja, they let the mystique and romance of the land take precedence in what amounts to a pure gamble.

You don't have to be 100% accurate in either estimating value or rehab, but if you're not in the ball park you'll be offering potential buyers crummy deals and they will just throw those away.

Im not sure how any comp program could accurately provide that information without pulling it from the MLS. 

Likely your going to have to bail or gamble and complete the closing.

I do plan on walking the property with my realtor and a contractor for more accurate numbers.

How do I get an accurate estimate of repair cost when analyzing a wholesale deal, if I don't know how much each repair will cost?

This is just my layman's opinion, which may well be wrong, based on your chain of events, which may not be accurate.
