We live in Florida. We are in the process of moving to a different home. We have been in this house for over 5 years and are at the end of a 6-month lease at present. Our rent has increased over this period by $240 per month. I have a receipt for the initial rental period that states we paid first and last month's rent and a security deposit. Since I have this receipt that states it is for first and last month's rent, are we responsible for the increase as well? We were never given any notice of where the advance rent or security deposit were to be held. He has never informed us whether he put it into an interest-bearing account or just stuck it in his checking account and spent it. It is my contention that he should have been paying us interest on the money and, at the very least, should take any increase in the rent from that interest; which at 5% should be enough to handle any rent increase. What are our options?
