He’s cleans the common areas of the park like picks up litter, mowes the grass, etc. he lets me know if there are any violations.

Anyways before closing I addressed all of these concerns with the seller and was presented with a signed and dated termination / notice to vacate from the problem tenant agreeing to be gone before or on March 31st, today.  

People receive notices like, "CONGRATULATIONS! 

My question is as the new owner, does that lease still have to be honored by me or can I redraft a lease (with a lot of the same stipulations) but giving them 60 days notice of a increase in rent?

I know it's short notice but they need an answer today or I I'm guessing at least one will walk away.

Landlords in Allentown, are you noticing your improvements to generate a higher quality tenant, or is it hard to not be a slum lord in Allentown?

Unfortunately, your friend got wrapped up in that type of situation but I don't think that's all that common amongst service member landlords. 

I just did a drive by today and noticed my tenant is storing an excessive amount of household items in the yard, including indoor furniture. 

The offending individual gets a chance to respond to the notice.

I did notice that when he analyzed a deal, he was able to click on an option to re-evaluate a deal as a different type of purchase, such as a BRRR deal, re-analyzed as a Rental Property.
