HUD usually requires 60 days notice + to the end of the month for the new rate to take effect (notify Mar 2 and you can get it Jun 1). 

At the end of this lease period, this lease will automatically renew for another 12 months unless the tenant gives a 30 day written notice of intent to move."

Someone else can probably help with the exact process in PA, but it generally starts with someone (you in most places) posting a pay or quit notice on the door.

This is also even before you account for any reserves for expenses such as potential vacancy rate, small monthly repairs, or large repairs like capital expenditures (like fixing the roof, HVAC).So I notice when I try to do these calculations on properties, I can almost 100% of the time afford a triplex over a duplex, even though it seems like it should be the other way around, BECAUSE the additional rental income of the 3rd unit really helps lessen how much I would have to pay for a mortgage.

As per the NC statute concerning lease terminations, I should have sent them a termination notice ("notice to quit"?)

I also do June 1st to the next May 31st with 45 or 60 days notice. 

I always ask the Seller to send a written notice to the Tenants regarding the sale.

You'll notice I mentioned that dynamic one month ago in post #2 of this thread. 

Can I renew the lease with market rent after proper notice?

Does anyone in Indiana have a notice to quit form that they like to use that wouldn’t mind sharing?
