Since the water use was variable and there was no water damage to the property, it would mean that there could not have been a water leak.

Without knowing the many variables needed to know if this is a good deal, I can tell you right away buying at 80%+ ARV is a bad idea, especially with the issues you mentioned.

The variable interest rates bother me, but the balloon payments sound like a recipe for disaster.

I have looked at the metrics for airdna and looking on airbnb its self but i am still running into a few variables i cannot account for. 

There are lots of Variables that need to be taken in calculation .Remember houses on the market are NOT like wine.

The main thing is to address as many of the variables, UP FRONT, so that there are no surprises later.

Rates are heavily dependent on FICO, LTV, Term, loan size, and other variables. 

Many museums that allow photos nowadays play with variable-colored light in their indoor spaces to keep tourists with nicer digital cameras from accidentally getting the highest-quality shots of their pieces.The appraiser is going to get fewer opportunities to get shots to justify a lowball appraisal if your property is very bright and the lights are at the daylight-colored range.

.- I'm under contract on 3 places right now: one is an A class in a great area, another is a solid B+ in a decent area, and this one is a lower-income one which was pitched to me as a B-- The purchase prices of the 3 homes I'm under contract with are pretty variable: 147k, 127k, and 70kMy goal with these purchases is to build a small portfolio of homes across slightly different neighborhood/risk types.

Not sure about the rest of the variables.
