Recent comps for the area, have two bedrooms selling for the $190 range (thought it has a carport that ours does not), and ours is larger 3/2. 

I still work on those but deal size has to be larger.

You are correct SD is not the best market for SFR total profits.

because the products wear out over time, typically foundations don't settle much morewiden bases out slightly larger and higher the load is limited down force after a standard repair area.sinking may occur however remember a lifetime is typically a 20yr period, limiting this period to conditions make it a limited lifetime.marketing to people not realizing this.

After paying for the water and the electric, what's your profit/load?

It is a niche that you have to feel comfortable playing in, but can be profitable if done right. 

@Henry Perez just curious what kind of net cash flow/profit are you expecting on a 100 unit Central Valley property?

$24,000, or however much you have available outside your other investments, isn't really very much to start with, definitely no where near enough to generate $4-5,000 of profit a month.

Your list of cities/school districts pans an area larger than the entire state of PA.

You close on the property yourself..by now you should have a feel for the game, know how to get sweet deals for the low low and more importantly know how to calculate repairs...yup..close on it yourself...no end buyer no assignments..that 40k profit is all yours..... hire a contracting company or if your a hands-on guy...
