There must be some "big data" out there saying that statistically you are too likely to refinance in <3 years with a rate that high on a 15YF n/o/o investment.

That would be located at the county Viatal Statistics department.Whomever filled it out (relative, sibling, son, daughter, etc.) will be your first point of contact or if you since you know of the owner's name check to see if a probate case has been filed.Probate laws vary from state to state and my understanding is the property is going to have to go through the court probate process.

I saw a statistic the other day that the number of evictions filings has decreased by a significant number. 

Even if you are approved for every line of credit, it still shows as negative because statistically it signals financial trouble.

Are there any statistics as to what percentage of NPLs with equity go back to the lender?

I have recently posted statistics for Milwaukee 2019 YTD - both DOM (days on market) and inventory for sale are down - again - over last year.

Some interesting statistics regarding residential income properties in Miami-Dade, Broward, and Palm Beach Counties: Average Sale Price vs Average Days on Market for each month, so far this year.

Please see my replies in bold below. 

The statistic of 50% or more selling within 7 years does make a great argument for looking beyond cash flow.

@Sarah Vance - did anyone back that up with statistics?
