Demand is super high in the area. 

OR is it that there is soft demand with no buyers?

Again this is not in the public record.Just as importantly is the other factors that  drive supply and demand.

A good way to determine this is by contacting a property manager or investor friendly agent as many times they are aware of the demand for certain areas in your market.

Oh and I have a very demanding full time job as an energy trader at an investment bank.  

The reason you have such crazy tenant laws is because the high demand...I'd much rather be dealing w this crazy government interference that generates WAY more media coverage than real impact to either side of tenant or landlord.....Than C class tenant...Trust me when I say I have got the best tenant experience in San Francisco, for 10 years....

With the increase of baby boomers retiring, and people wanting to downsize earlier in life, there will likely be an increase in demand for these types of facilities. 

Cap rate is generally a measure of risk and how much properties are in demand in a certain market.

My job is also pretty demanding and includes a lot of travel.

My Airbnb-found summer rental tenants (1-3 months) have been more demanding while paying approx the same price as the people I find on craigslist.
