.- Long term:  "I will have more than or about 5-10 cashflow producing assets making me 5-10k a month in profit. 

Not having to work in this example means having the 15 rentals producing enough cash flow to pay all their costs, including all 14 old mortgages and the 15th (new) mortgage that is refinanced each year.   

We can “split hairs” on this topic, but let’s just accept that our different experiences have produced a somewhat differing view.  

The issue with this is HYSA will probably produce better ROI for now.

There is no debt service coverage when a property is vacant/distressed and in need of rehab to produce a rental income situation.

I think the worst are the ones that will say they can do something for you or bring something to you then do nothing at all/fail to follow up or stay in touch (lack systems, organizational skills, and actual work to produce).

.- I was able to get access to private investigator software to find the true owners of these properties since conventional skiptracing produced poor results.  

The income it can produce and the networking would be worth it.

When you say a man in debt is a slave, are you referring to debt used for personal items, or are you including debt used to acquire income producing or capital appreciating assets also?  

It makes little sense to keep the property in Dallas since it's producing practically no cash flow.
