Are these the only items we need to document?

Quote from @Chris Seveney: @Charlene Kingsnorth have you had an sec attorney also review what you are doing as if you're are having multiple people as part of a loan participating in it depending on the state this could get you in hot water - so be careful  good point Chris some state allow fractionalized deed of Trust mortgages other do not or require PPM like documents prior to offering them..

They work on contingency, so it costs the plaintiff nothing unless the attorney collects from you.Take a look at: https://www.fcc.gov/document/f... 

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

.- Review the loan documents, there is most likely a due on sale clause, which is why you won't find a title company to process these for you.

That's about what mine cost to set a living trust with the documents you mentioned.

However, about eight days later, the seller informed me that they had "changed their mind" and no longer wanted to sell.In the weeks that followed, the seller failed to provide the required documents, including HOA disclosures, the seller’s disclosure, and other essential paperwork, all of which were due within specific timelines per the contract.

The gentleman Chris Koerner seemed well educated on the topic (mobile home park investing) and he gave enough information and follow-up documents that you could take the information and run.

I was supposed to close yesterday and they were asking me for documentation.

Also be sure your PM is documenting everything if you already started demo and rehab.
