this means that these owners are under much less pressure to sell, and so they don't really care that their price won't let the property be a good rental. 

Good summary of what your market is looking for but as we all know, each market tends to have its "wish / want" items which differ from market to market.Flow is definitely a selling point but make adjustments come with a cost. 

Buy at a discount given the lack of building potential and can always pass that discount along when I sell.2.

If you don't want that, I would sell it or put it into storage (which may not be financially feasible), but long-term renters are hard on furniture that is not theirs. 

We sell about 5-6 of these a month per unit.

You'll learn what contractors are good at such repairs, and eventually people will start bringing you "problem properties" with that issue.Another related idea: contact a good local realtor and ask them if they know of any on or off market properties that would be a hard sell for most buyers. 

If something happens to the country and foreigners leave, you won't be able to sell.

I plan to sell my Vegas condo and it looks like I'll be able to make about a 35-40K return.
