It appears to me that she failed to maintain premises as well as failed to advise you of leak in a timely fashion.  

Personally, I think it's unreasonable to tell tenants they can't hang any pictures or artwork.  

In this letter all negative consequences for the non paying tenant are explained in an easy to understand fashion.

This statute preserves your right to pay rent by check or some other old-fashioned method. 

She gets upset and tells me she will have to do the cleaning next week when she is off . " No , your lease is up today , You will have to wait the legal 45 days for your deposit , AND i see you painted some walls , someones crayon art work is all over the door , all the screens are missing , the grass wasnt cut , you wont be getting the full deposit back "   She then tells me that she will get most of it back , 2 gallons of paint is $50 , cutting the grass is 30 . and the screens arent her problem .

I did this all the time with people relocating and renting sight-unseen from other states/countries.Or do it the old fashioned way with a fax.  

Cozy, Quicken, rentpost, appfolio etc.Buildium allows me to enforce rules without being the bad guy and lets me collect payments in the form of electronic check, debit card, credit card or good old fashion cash.

In typical fashion, replies after a couple of weeks that she is interested in renewing, no mention or inquiry of rent increase on her part.

These eviction services are no substitute for good old fashioned detective work.

Call me old fashioned.
