It's probably going to drive my GC's guys nuts.

@Morgan Van Ness - there are a lot of factors; location, condition, utilities, long term tenants, ectMy clients have rented 2 bedroom units from $800 - $1800sometimes you see properties with tenants for years and they don't raise rents.I have units with tenants for years that are good and I don't raise their rent

This drives me crazy as the listor is looking for more than the list price regardless of whether there are other competitive offers or not. 

Similar to a Driving test.

I cannot determine the rehab costs by just looking at pictures on my own and I know time is a key factor for wholesalers.3.

Not to mention some of these countries have unemployment levels as high as 30%, so you could rent to someone who has never had a job, may not speak English and can't drive a car. 

I lived almost 4 hours away but I'd drive up on Monday morning with my supplies and work the 4 cities close to that house, and sleep on my air bed, during the week.

That won't cover the "hassle factor" which you should also consider, but from a numbers point of view, it is very enlightening.

If the reason is something explainable then it may make sense to take other factors into consideration and get a larger deposit to offset credit score.

Your gain is determined by the difference between your adjusted cost basis (acquisition plus cap expenditures minus depreciation) and the net sales price - debt is not a factor.3.
