If you want to do this as a business or scale it, turn key might not be right for you but if you are out of state, have a busy life, out of state and can't effectively manage a project, then turn key is a great alternative. 

It is more appealing than the alternative.

What is the alternative?

Right now I don’t have alternative investments for the $8,000 but something always comes around.What are your thoughts?

If you don't then i think you might look for alternative option which does not involve using (TAHX) Program cause this criteria will be evaluated.

Also, an alternative offer to the seller is her full asking price of $322,000 but at a 3.5 (or lower--how much lower?)

OK seriously...Let me just show you something :And a few leads from a few days ago.This obviously does not include all the phone calls we are getting, nor the alternative ways people contact us after seeing our website...Do you know how much I spent for these leads?

Or, alternatively, to get out of the PMI after a few years? 

By the way double closing isn't illegal, I have done it too, you just have to know the right way to do it but I don't recommend this technique unless really particular circumstances.
