I rolled some debt into the deal to make it more attractive to the bank.. more profitable for them.

It's nice, so you should be able to attract quality tenants and get maximum rents.If you need someone to pull MLS data for you (like the listing) or other comps, etc. just let us know and we can help you get more information that may help you make a better decision.

The prices are SOOOO attractive right?

If nothing above applies, its most likely a deal that should be relooked because its not very attractive.

@Gissella IrazabalI would do portfolio/investor lender, even though their interest rate not as attractive, you can still find 5-6%.

When I calculated at $950 rent the numbers were obviously a little less attractive.

That makes this very attractive as I can do that 3 times by October for a total of $120.000 each, which should total my possible equity borrowed.

The only way this might be attractive is if you have the property (park/pads)...That said, it's a low-class market...how many people in your city are really looking for mobile homes?...

My best guess is it would take around $60k to make it attractive enough to fetch $400k. 

Other investment (non real estate) opportunities look more attractive as time goes on.
