And given their recent late payment history, I don’t know that they’d qualify with another lender. 

So you move on.I also like Robin's Saturday morning group in west FTW. 

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

The listing showed a price and transaction history for the home.

Here's a list of things to track:- Formal lease application- Formal signed and executed lease specific to your state- Payment history (I recommend using online rent collection like Apartments.com, RentRedi, etc)- Maintenance requests and receipts- Accounting for all rental-related expenses (repairs, utilities, etc) The more you treat it like a business, the more helpful you are to your CPA come tax time. 

If you are into positive affirmations, the Miracle Morning, Tony Robbins, etc. then you'll enjoy that aspect. 

In neighborhoods that won't attract high credit score tenants, I've found that a stable job history with a MINIMUM of 1 year at current or previous job to be the best indicator of a great tenant. 

Verifying last 2 years of rental history very important!

Verifying last 2 years of rental history very important!

I would underwrite buyers based on stability of income, financial payment history & ability to pay.
