And you'd be shocked at how fast things grow back. measured in days not weeks or months if has moisture. 

The guests have a credit card on file and your policy should allow you to charge for damages or excessive cleaning.

I personally don't charge for small holes and touch-ups unless they are grossly excessive, but I would charge for removing the tape/adhesive.

Moisture in a bathroom is killer.

I have never held a mortgage 15 years (or even 12.5 years) and I have had quite a few mortgages.I claim that it is better to have the negative cash flow and use the $450k to achieve a return in excess of the 6%.  

Next steps are to put down a roll of plastic to prevent moisture or wet floors. 

Otherwise, the dry ground will suck the moisture out of the ground. 

The only thing they didn't reimburse was excess cleaning (they said they don't reimburse for that) and honestly, I find that as cost of doing business.  

All it's doing is applying excess cashflows in your budget to principal payment.

Any excess proceeds not applied to the investment portion may be taxable as "boot."
