I have however, received good demand from nurses for my studio in Austin that rents for about $2100 per month. 

Traveling nurses and workers in the tech hub are common answers, does your market support the demand for them?

The suburbs do well with appreciation and being in high demand because of good schools. 

Are you cognizant of local supply/demand and buyer and seller competition?  

In the end part of the hostile dispute to get money from me she claimed I should not have chanrged since hers is a service animal.

Just remember, while initial cash flow might be lower, Denver's still a hot spot for long-term appreciation, and its rental demand means you shouldn't have trouble finding tenants.

Typically houses/properties that have well water and a septic system have them in opposing yards, and code typically demands a certain distance between them. 

(Per the Sarasota county Economic Development Council) LTR in that market will likely be in demand.

You can play with pricing to see how it affects demand, so you have a better idea of the quality of prospects and how many you get at different price points.You could also then modify your ad to identify a target MoveIn date and start accepting & processing applications.

That leaves I guess SFH.Think about what your demand drivers are and invest around those demand drivers.
