Thanks to @Jay Hinrichs who reviewed the documents the fake title company sent me and said there were so many things wrong.

Document List (state.ny.us)

Is there any type of document I can make the buyer sign for these 2 weeks he will be occupying the property in order to cover myself?

They will tell you to submit your request in writing and give you an email address or mailing address.

I document heavily with photos before they occupy, I take photos during every walk-through inspection, and I document what condition they leave it in at move-out. 

**Legal Documentation:**You'll need to work with a real estate attorney who specializes in condo conversions.

Name, address, email, and phone number is all you need.Follow up with an email, as appropriate.

I was finally able to obtain the zoning permit after attending a new hearing before the ZBA in May 2024 and the received the documentation in July (I also don't understand why it took two months to receive the paperwork).

You do not need to wait to cash out on the new value as long as you have documented rehab work.

Have all those names first/last, phone, email, address, birthday, anniversary, etc.
