Was that the exact and only language used?
If you did not enter the "original" agreement, and you do not want to enter into the new agreement, then you will continue to negotiate the terms of your rental.Quoting citylimits
This would be a new agreement that you signed, to stay for only 29 days with the possibility of extension, and for which you did not complete negotiations for an extension?Quoting citylimits
Stating that you "may need a couple more days" is not actually a request for an extension -- it is instead notice to the landlord that you may be requesting an extension. But assuming that the landlord was receptive to your need, and agreed that your move-out could be delayed for a couple of days based upon medical need, what did the landlord say when you reminded him of the discussion and asked if you could be out on day 31 or 32?Quoting citylimits
The easy way to stop those inquiries is to give a firm move-out date.Quoting citylimits
If there was some sort of oral "cash for keys" agreement that was never made part of a written contract, you have a problem. But that aside, if you failed to move out at the end of your contractual lease term and continue to refuse to give a move-out date, even in a "cash for keys" scenario you would have trouble convincing the landlord that you were entitled to anything. "Cash for keys" agreements involve the occupant's moving out on the agreed date and leaving the premises in an agreed condition (e.g., "broom clean").Quoting citylimits
The buyer should have informed his lender that the initial occupation would be by you, as a tenant, pending an agreed move-out date; but that doesn't affect your rights. That's between the buyer and the lender.Quoting citylimits
He apparently promised to "take care of you" if you moved out by an agreed date? But you haven't moved. So what promise is he actually breaking?Quoting citylimits
