It sounds like there are problems regarding infrastructure like roads and water supply.   

Even though this factory has supplied homes for assembly in the US, the building codes are very local. 

One became an enterprise, one became a veterinary office, one got demo'd and had 10-15 townhomes built on the property, and there is one in my neighborhood that has been for lease for a couple years now and still vacant (not sure if the owner is really just land banking it, since he owns the adjacent property too, a former medical supply store).All that being said, I do not see this property as being something that will be easy or cheap to re-lease.  

A place like Austin, TX has been over built and rents are going down and vacancy rates are going up vs. a small market like Reno, NV the rents are increasing because of a lack of supply and driving appreciation and prices up. 

Running a self-service car wash may not take much in the way of experience but as noted above, there are a number of maintenance/supply issues, etc.I would also strongly recommend getting tax return information for historical performance.

Rather I'm looking for a mature STR market with enough supply that makes it worthwhile for my co-hosting business to bring our services.One variable I'm digging into is how many STRs are self-managed vs managed by a PM or co-host.

We also supply detailed cost analysis once a property is identified.

Classic supply and demand.

I agree there may be times to lower the rent, but in my cities, county and generally state I have found that to be rare   Other parts of the country have different economic, real estate and supply & demand situations.Ultimately it is the market, laws & condition that determine what rent is appropriate and what the community will accept. 

The Supply in Hazel Green is very low3.
