Probably a smaller number of sellers, but I’m not looking for a ton of volume myself, I can only take down a few great deals a year...I tried to compile a list of every owner of property over 20 units in my whole MSA. 

I vote for buying a compiled list with the correct absentee filters from listsource..

We compiled ~50 addresses of maintenance - deferred houses and run down properties.

Most people compiling equity lists also skip anyone who have been in title less than seven years or so.

In fact, both mailing houses and list brokers actually get their data from the same place: list compilers.

So I have my very pricy list (inheritance list  that was so pricy ughh) and a list I compiled myself hopefully a very targeted list of highly super highly motivated sellers, and I am sending it out.

determine how many SFR have 30-100% equity that are in the bottom, middle and top 1/3 under the median sales priceAll of this data is compiled against certain factors and percentages and tabulated in 2 different spreadsheets and then is ranked.  

Jay im gonna take all the great adviceYou give on BP and the podcast episode you did and compile it into an ebook for millenials amd newbies lol.  

Additionally, I'm compiling extensive data on real estate deals across the country for an educational endeavor called Dealsletter.

Give me 30 more years to compile the data for you and I'll have something.If I had to guess however, some of the markets that have performed the best over the past 30-40 years would be:San Francisco, New York, Los Angeles, Boston, D.C., Denver, Portland, Seattle.
