@Char BachehTypically no you do not need to open a new business you just file your existing company in NJ as a foreign entity.

Research the probate file again.

Also check (search) the files of BP there are question worksheets wholesale /flippers use when talking to owners.Once you have the above information ask the owner if you can do a walk through (if the place is vacant) to look at it and gather more information. 

This was just my experience filing taxes with my house hack the first year.

Let the tenant know that if they block entry, you will consider it a breach of the lease and you will file for eviction in a couple of weeks when the courts open up and also seek monetary damages for any extra incurred costs from the delays. 

Well, next month came by and she didn't move out so we filed an eviction order, a few days later evictions were canceled.

Also keep in mind if you are looking to do a JV with a complete passive investor that would be a security and does require filing and exemption with state and federal SEC.

She may have to risk you filing a judgement.

Rest are bankruptcies, liens, code violations, D4D, probate..

Holding in a Qualified Trust Account or Qualified Escrow Account will protect you in case your QI files for bankruptcy and as you know, these are unprecedented times.
