I definitely have to do it to close with my seller but is the bets thing being upfront with buyers and saying "this is how it is" in case they fall through?

I bet you can get pretty good eye's on some areas of Huntsville using Google Maps.

However, I'll bet it will come up when the property is finally sold in a more conventional sale.  

Best bet is check with an attorney and take a look at the local laws along with the rpl and rpapl.

See how nice and helpful people can be when the situation is correctly stated :) @John Andruszka   SO Ya your next step is post pay or quit then file for non-payment, eviction, she's not gonna pay you a dime. is my bet and I bet I'd win that bet..You have no guarantee she'll pay rent, you've given her 2+ extra weeks to move..

If it's 5+ units, all bets are off and you need to seek commercial financing, which can be tough to obtain when you're just starting out.

You bet. 

That building is very close to the zip code in question and I bet it's worth maybe $30k today.

As to the upper floor space, I would bet a dollar to a donut you don't have the right framing for it.

I will bet dollars to donuts the 18 month 0% is a credit card with teaser rate.or the guru has bought down financing rates from a unsecured lender.. which they pay for out of your 25k.
