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.  

Without evidence, it's hard to say.First, you should educate all of your tenants to report excessive noise to the police.

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.

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

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. 

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

Interesting to hear that they are claiming that a lender sold all of their loans and kept the excess funds.

Moisture in a bathroom is killer.

Rent control measures, burdensome employment regulations, and excessive administrative requirements exemplify this.
