Do not allow the seller to return for personal belongings after the close without some type of documentation on when they would have everything removed.

This is an area where members can share spreadsheets, forms, documents, pictures, and more.

I looked at their documents and had very little idea how to vet their information.

I didn't expect to see these results before cracking open hundreds of recorded documents.

Thanks, I will locate the closing documents and review the lease. 

Quote from @Stephen Bruce: I have a pretty good document I share with tenants as soon as they give notice.

I think the other commentators have it right - a HML that is willing to take an investment that is small is probably not vettable and not a smart play - however if you have ~$500k or more to put in, then the legitimate more easily vettable firms would pottentially be interested - and you would be able to see the sophisticated setup, documents, structure etc and be able to research accordingly

Your current setup doesn't really keep your business and personal assets/dealings separate.To do so, you'd need to transfer those properties to an LLC you own or create a new one for that purpose.If there is a lawsuit, I'd imagine that your name, as the owner,  would appear in the documents filled.Just my 2 cents, I am not an attorney, nor a CPA

When the funds have been properly sent, deposited, and received in the account, this document shall become effective.

This was all documented the lease.
