Supply and demand is what it is about.If suburban go out 3 miles.What is WALKABILITY and population levels  for the area?

The downsides I anticipate are lower demand, lower rents, less liquidity/harder to sell, difficulty getting contractors and handymen out there.

I am in software and it is very hard for me to hire enough developers here because of the growing demand.

However, unless you do the work THEY demand you do (fyi be coachable to every item... which could conflict timewise with your job, family life, other commitments, etc) you don't get a dime back.

This is due to less competition, low inventory / tenant demand for a finished product in these areas.  

No, you will need money set aside to handle capital demands related to owning and dispostioning the asset.

Spain, Italy, France.You can find rising demand for holiday locations in Europe.Greetings,Reapall

Lots of demand at my lower price range, $80k ish and $750 to $900/mo rent/mortgage payment range.

I haven't seen a buyer demand a higher Option Fee than whatever I propose. 

It's a combination of cost, demand and also the required software to integrate.
