RE: MY FIRST ANSWER BELOW TO YOUR QUESTION. We finally got the tracking number from the landlord on a text msg and yesterday, I went to the PO & got the certified mail with a nasty letter and some computer copies of damages ( they claim) but no receipts AND NO BANKBOOK as required by law. That's because they never opened an account as they should have according to law. They said their time wasn't worth arguing about $900. But they only added on &90 interest which was short about $80. She workes in a bank & could have gotten the exact amt from a bank program but since we got $990, we're happy and it shows they did not follow the law so they knew it & if we went to court in NJ, they would have had to pay double the deposit and double the interest. I wish you luck but you have to pursue it.
Mr. Shalfrey who commented after me has the best advice for landlords ( I used to be one) go to the bank immediately and open an account in two names yours & the renter but the landlord keeps the book & let the bank do the interest calculations when the tenant gives notice. BUT, because of circumstances, we did not do a final walk through with them and left them a fairly new stove, refrigerator ( there wasn't any when my daughter moved in) and some other great items. They said they never asked for them so they do not enter into the story. Bad people who tried to get away with it. Don't let anyone get away with anything.
Again, fight it for the principal. We would have rather paid a lawyer with the money than let them have it.
