2. Complete your Lease
3. Move out and leave the property PERFECT
4. Do a final inspection with the landlord.
5. Demand your deposit back. He is required by State Law to have your deposit in
an escrow account and not be co-mingled with his own funds. Demand to know the Name of the Bank where the funds are held, it is still YOUR money and he is required to tell you. If he fails this the contact the Florida Real Estate Commission. They take a dim view of Landlords messing with tenants money. It does NOT MATTER if he is a real estate agent/broker or not.
As far as those people coming around and bothering you, they are the property preservation people hired by a 3rd party called the Asset Manager and the AM is hired by the bank. The next time these property preservation people come around get their identification, they are required to show it to you. If they don't, call the law. As long as you are paying your rent you have a right to Quiet Enjoyment of the property and they are violating that right. Too bad your Owner is a Schmuck
I'm sure you're right: You won't get your $1,050 deposit back.
But the other answers are correct: You owe the rent to your landlord, regardless of whether he's paying the mortgage or not. That's not a condition of your lease.
Meanwhile, you've got the possibility of a rental agreement from the mortgage company. But if you pay your rent (and don't regain your security deposit), you won't have the money to enter into the rental agreement.
If you've been served a 3 day notice, you definitely should respond to it. You can't ignore it.
The proper thing to do is to pay your rent. You do owe it.
Alternatively, you might try negotiating with the owner. He lets you stay a few weeks rent-free, letting you build up some money for your next rental. You then move out.
Or start looking for a new place immediately. You've got the kids to worry about and care for. (Could you all move in with your dad on a temporary basis?)
Or--and I wouldn't suggest this--is to pay the rent this month. Don't pay it next month. Meanwhile, work out the details with the mortgage company on a rental agreement. They foreclose and you rent. You're still out the security deposit--that's long gone in any case. And it would be a stressful several weeks. And there's still the risk the courts might move fast enough to evict you. (A lawyer could advise you on how fast the courts move on evictions where you are.) Again, understand: I would never, ever suggest that you not pay your rent. But someone else might not have the same reluctance. ;)
Hope that helps.
A suggestion that might be acceptable to all parties (and make sure to get this in writing) would be to have an attorney hold the security deposit or to place your next month's rent into that account in place of the security deposit.
