These strategies would will grow you cash flow safely without dealing with a bank. 

Could anyone provide guidance on how to obtain the contact information of an underperforming host on Airbnb?

Borrowed money from friends and family to pay cash for the property as the bank would not finance it until it had been remodeled, made livable, and brought up to code.

A double-entry system (like QuickBooks) allows you to reconcile your bank statements, ensuring no missing or duplicate transactions.

Quote from @Quinn Olivarez: If I were the original seller, I would tell the bank I sold the house so that I could get the ball rolling on getting it out of this sub to agreement that is probably not enforceable in most jurisdictions.

@Vijay Singh SambasivamI would suggest speaking to local banks, and credit unions.

Another way, you could connect with a host via Airbnb/ VRBO Facebook groups in the area you're searching and ask them what they do and how they handle it.

I host a free virtual one every Wednesday (that is not new years day) and would be happy to send invite if you like. 

Further, I don't trust other host reviews.  

My attorney told me in 30 yrs he has never seen bank enact due on sale clause but he has seen multiple landlords get sued without LLC protection.
