Fellow STR owner/manager from TX.I do think there is value in having some pre guest documentation in the event that you have a guest come in and make false claims about cleanliness, etc. 

So, communication and assignment issues, as well as not being able to explain the maintenance issues and the required work.3) Proper documentation and quality of work issues.

HELOCs are much tricker than a closed end second - they don't typically allow you to close in an LLC and they are full doc qualification, meaning your FICO, employment history, income, DTI etc all come into play.

Document the condition they left it, keep receipts for the charges, and charge it to their card.

Which one do you have the most favorable information on based on their past rental history and not what they say.I suggest using a service like Mayistay.

Your credit, investment history and bank statements will likely be evaluated and you'll need to personally guarantee the loan, but you can close under your LLC.

A general rule of thumb though (not a hard rule) is that if a market has a prolonged history of vacation rentals such as towns whose commerce is very dependent on tourism like beach or mountain towns, then there is a good chance than those towns have established their airBNB regulations decades ago and are likely stable.

Solid employment history.  

The 2005 loan shows it as a first lien so I assume they cleared the history somehow but they are unwilling to share the policy.

If there is a specific document you would like to see added next please comment in this thread so I can get it added to the list!
