Sometimes you get lucky.You could even bring up the subject of seller financing (search online for ideas of how to structure a seller financed offer), and make sure a competent real estate attorney helps write the offer documents (if it gets that far). 

Is there a specific document that I will need?

.- Tenant submitted a work order for low water pressure in 2 bathrooms- Tenant submitted a work order because the garage door doesn't close all the way and left a 2-3 inch gap at the bottom- Owner initially refused to address either work order- Owner demanding the tenants place furniture pads on each piece of furniture- Owner calling multiple times to speak through the work orders, asking when they've been scheduled, calling a couple days later requesting the invoices- Owner calling because they want to access their storage in the basement so they can remove several pieces of furniture being stored- Owner now emailing requesting multiple property inspections throughout the lease cycle- Owner questioning my experience and relative PM knowledge because I'm not following up with her in a timely manner (the following day after the work order)Keep in mind, this is 2 weeks after the tenants had moved in and the tenants are very happy in the home.This is something we see on a regular basis.

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

We submitted an unlawful detainer last August and finally got a response from the court in December.

Airbnb has never penalized bookings when the property is sold in my experience, just to provide documentation it was sold.  

We don't have that policy and I don't ever tell an applicant they can't apply I just make sure that there are multiple correspondences documenting our screening criteria.

In the event of damage to the product, you file your claim through them (take pics and submit).

Missing these dates can have dire consequences.Schedule third-party inspections early and submit lender applications promptly.
