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

Details matter: keep a log (something like an excel spreadsheet) that documents the date, duration, and events that occurred/work you did. 2.

You may also need to provide additional documentation, such as proof of income and employment, and may need to have a co-signer who is a U.S. citizen or permanent resident.In terms of buying with an LLC, it can be a good option for some foreign buyers, as it can provide additional liability protection and potentially offer tax benefits.

STR insurance provides broader coverage, including liability, property damage (even non-guest-related), and gaps Aircover might not cover.For damages caused by guests, document everything (photos, receipts, estimates) and file a claim through Airbnb.

If so what documents were used?

Also consider all lenders will require to review your insurance when underwriting a loan and it's likely a violation of your existing loan documents to let the properties go uninsured even if they didn't require insurance escrows. 

For example, I have a tenant portal where they can pay rent or submit maintenance requests.

Are you researching this yourself or asking your borrower to provide documentation to support this?

The sooner you regain control, prove that you fully intend to enforce the terms of your lease, and that you will not be 'played' by their recall of events or documents, the more effective this action will be.  

This will be my first year submitting from Baselane since I switched from QuickBooks Online and it's already infinitely easier!
