There might be a 30 or 60 day notice clause that requires you to let them know in advance if you're moving.The offer will depend on the rental income and how comparable properties sell in the area.

The product can be a bit more appealing compared to FHA since there is no mortgage insurance involved.

That's not what i've seen based on cashflows from a turnkey provider there whom i've compared to other markets across the US.  

It allows you to compare which are more favorable.On your second point, some turn key property providers are excellent, but they are not all the same.

As a financeable asset, it is evaluated like residential: it is appraised by comparable sales.

That's when you need to compare income to expenses and money cost and figure out the cap rate, etc.   

They are cheap to buy (compared to a typical SFR) and produce good cash flow.

As I stated previously the advantage to rentals in Philly that they fill up quick and tenants tend to stay longer compared to the burbs. 

Kept searching all over upper coastal areas of FL, only reason honing down to CC because of the amount of development happening and by the number new properties coming in the market compared to other places whereas most properties in other towns mostly old.

I have contacted 3 banks that have refused to lend on a property because there are no comparable properties in the area and if the appraiser can't appraise it correctly, they can't lend.
