@Russell Payne there are too many variables to give a flat answer.

I had a flat concrete slab (shaded) where I put it.

I don't like relying on appreciation, especially in a relatively flat market like ours and California seems to have a large number of problems, affordability issues, consistent outmigration, etc.

You need to bake the utilities into your rental amount and pay the bills on your end. 

For example it is waterfront, is a flat cleared lot next to a tourist attraction with insufficient parking, it is positioned next to a church or other type of building that may need overflow parking, in between to meticulously maintained houses, or in an amazing school district.

Large wrap-around covered porch and a small flat yard to enjoy the amazing views.

:New Orleans is flat.

SC has  a state bill that is going through its paces that would make it illegal to flat out ban STR's.HOA's could not prohibite STR's if this passes, nor could cities. .

Is a reasonable seller really going to flat out reject any buyer who wants to see historical data? 

Esp now that appreciation is flat for the last 1 1/2 years.
