I'd bet on Austin over 30 years, but again, not necessarily relative to SFO. 

@Phillip Austin we've looked into these and it's our opinion they should only be used with Class A tenants, maybe Class B - deifinitely NOT Class C or D tenants.Several companies in this area will no longer allow S8 leases or tenants under 600 credit scores - because of the high number of claims & corresponding claim amounts.

Based on the rents, I would guess the $1350 house is in a C+ or maybe B- area, and the $950 is in a C- area.What neighborhoods or zip codes are these in?

Now these would be A and B  properties not C or D class  

I do not see pulling off this type of increase in value in class C or D markets. 

There is also a significant investment happening in the Buckeye area that should drive appreciation in that part of town in the coming years although currently I would classify that area more as a C- or D+ depending on the street.Best of luck to you!

Good rundown Lee, although I think suburbs like Grandview and Raytown (while great rental markets) are more like C+ or B- areas.

The departing tenant says she will continue paying rent, but I wouldn't bet on it.

When you see what people do with old space heaters, guards and safety removed, plugging in several in one overloaded extension cors,... you can see where the concern is coming from.

Now some investors will argue it is not a D area but a C - or something.
