I admire that you've handled most of the filings yourself, but I’d prefer to take a more hands-off approach.

You may need to register as a foreign entity, file a tax return, and pay taxes in PA.

The loan doesn't decide its lien position the order in which voluntary liens (mortgages) are files determine that. 2.

I've done deed searches and look at different documents filed.

I don't want to have to file separate franchise statements.

I found this fact sheet which seems to indicate it would be possible to evict the rent stabilised tenants so long as they haven't been living there for more than 15 years or are older than 62 or disabled: https://hcr.ny.gov/system/files/documents/2020/10/fact-sheet... 

If I could attach it here, I would but I will DM you the file so you can take a look.As far as an agent, if you would like assistance while you're here, feel free to reach out.

If the seller files for bankruptcy, that will involve you in a legal proceeding. 

Review the quality of the tenant base (do they have a history of paying on time, what were the original screening criteria, do they have applications on file).

Basically all rentals, even ones owned under LLC, come up during loan DD as long as you file them under one tax return as personal, that was what happened to me earlier.
