So I wonder can the gov loans really have a significant pricing improvement?

If there is one in it, and they are (I assume) well past that date, I think the P.A. is null and void.2 - Do you have in writing that the improvements that were paid for by the "buyer" are at the buyer's expense and will not be reimbursed by you at closing, or will not be credited in any way towards the agreed upon P.P.? 

Floors, Electrical, improving the square footage, and basic remodeling to update the place.

Would I be able to combine a loan on the tiny home and the loan on the land and get cash out as an improvement? 

You can also do this on your own, but the agent will be able to narrow down many options and if they're really good they'll uncover some gems or off market deals.What I suggest is doing basic deal analysis on each of the properties you visit and you'll improve the "math" skills that you mention you struggle with.

I rehabbed it with additional 15K in improvements.
