Landlord wants to raise the rent by next month with no lease agreement. He lives in Florida the house is in Kentucky with no up keep. Can he do this with a phone call?

The lease expired two years ago. Asked for thing to be maintained at the house, such as boards rotting on the back deck to be replaced, actually fell through, exterminating,windows replaced that are falling out, front porch legally is suppose to have railing on it. But nothing has ever been done. Can he legally raise my rent with a phone call today and wanting to raise it next month.
