I rent out a house in Pennsylvania month-to-month. My tenant paid his rent at the beginning of every month, and when collecting rent on the 4th he informed me he was moving out on the 6th. He was renting from me because it was cheaper to rent than live in a motel as he had been doing because he was in town for work, which was supposed to last for a year and a half (instead only lasted 5 months)
He said he got laid off and chose to not stay in town any longer than he had to. I said you know my house rents month-to-month and he said alright and paid his rent for that month, using his security deposit.
After him leaving, he calls and wants money back because he feels he should not have to pay the full month because after talking to his attorney, he was renting "tenancy-at-will". I feel this is unfair because I received absolutely no notice to have someone in there right away and regardless, he was there that month. So, what separates month-to-month rent from tenancy-at-will renting?
