I have no problem knocking on the homeowners door but I want to talk with someone in BiggerPockets that has experienced working with these type of leads.

My guestimate is that 500 to 1,000 of those properties were livable homes.The vast majority of those homeowners were only one year behind on their property taxes.There is no real money to be made from redemption of livable homes in Arizona though.

Ok I see, you guys are talking about pretending to "rescue" homeowners from foreclosure. 

You will likely find that some banks are much more favorable to lending to primary homeowners, while some may lean towards investors. 

Many tenants don't clean as well as as a homeowner would leading to complaints down the road.A 3 piece is much easier to keep clean, requires basically zero maintenance and is much easier to repair or replace if damaged.

Get a solid Umbrella policy and make sure to revise your current homeowner's insurance policy to a landlord policy.

Homeowner should have an adequate policy and you can use additional damage protection from services like Safely and Waivo.Yes, security deposits are normal for MTRs and highly recommended. 

It will be an STR with no personal use  Background: high income W2 job, no primary home (ADU on family's land property, happy twith this) so can't get umbrella policy with most insurers as they want auto and homeowners for primary home before offering umbrella  Quotes from foremost and proper.

I’m interested in proposing a rent to own deal to the homeowner.

They were prior homeowners and sold their house before moving into my rental.So, throughout the course of the year lease, she was struggling to pay.
