I'm going to go implement some of these ideas and come back with the results!! 

Success is not about the size of your business it is about the implementation of strict, no nonsense, unemotional business decisions. 

The underwriter is simply implementing the guidelines from FHA.

Every structure I have bought has had termites, bed bugs, or horrible tenants that we have had to "wait" out, and implement a plant to get the structure back to cash flow positive.

Easiest way is to work with an originator that has direct access to AUS (Automated Underwriting System) as well direct access to underwriters since most lenders like to have an electronic approval before approval.

Either tenants not paying, not paying on time, skipping, 3 times the make ready costs because the tenants lived so hard in them or when they left the took "Parting gifts", continual maintenance issues because they were older properties... after 5 or 6 years I never saw it getting better and never a way to be fully automated and stress free...

A LOT of different ways to implement this into your strategy or to make it your sole strategy for finding deals. 

I feel like property management should be pretty much automated.

What I have been doing is automating my operational processes so that I can do what I do best, buy the kinds of properties that I KNOW and have had EXPERIENCE buying for the last 2 decades, but being able to expand it without a lot of risk.After I finish the automation process, I'm in great shape to scale what I have been doing.You have 15+ years knowledge and experience.
