You just have to do it at the lock, so maybe you can get your cleaning crew to delete the old one and add the new one.

You could lose that month's rent, utilities, and be faced with $500 - $1,000 in cleaning and repairs.

I would tell him as long as he leaves the property clean so it can be rented .you will not persue him in court and you will still give him a reference.

Ugh, I hate water issues.Anyway, resident understands that the fix isn't immediate and asked if he could get a reduced rent for his subpar living conditions (collecting the water at the two windows, cleaning it up, keeping belonging away from the windows, etc.).

Be flexible on repair and clean out requests (obviously not applicable when buying a rehab).I hope that helps - and good luck.

the house is clean finished and the tenant lives there want to stay.
