Do I need a reason to vacate tenants on a month-to-month lease?

[Frank Hock]

Hello BiggerPockets Family,

I purchased a duplex back in October in Allentown PA. I'm currently living in the one unit. I did not vacate tenants when I bought the property which was a huge mistake, but I'd like to vacate the tenants now!

I do not have a written lease with tenants only that rent is due on the 5th of the month. I've been reading up on PA law and it looks like I need to give a minimum 30-day written notice (both posted on unit door and certified mail with receipt). But do I have to actually give a reason to why I want to vacate them?

Thanks,

Frank
