Here are a few good articles to get you thinking about good criteria:@Brian Ellwood wrote The 6 Pillars of a Great Rental Market and @todddexheimer wrote Finding Emerging Markets

If you fail on either of those two pillars, then your site will not be successful for lead generation.

Far and away the best home inspector I have ever dealt with is James Mason with Pillar To Post.

You should read Pillars of Wealth.

No matter what industry you are in or are trying to do there are 4 central pillars that you must convey when dealing with equity investors. 

And I call it the biggest pillar of Success. 

The decline comes as this year’s relatively cool housing and rental markets makes investing in homes less attractive than it was during the pandemic-driven homebuying frenzy of 2021 and early 2022, when record numbers of AirBnB were purchased as hotel and lodging surrogates (Redfin defines an investor as any institution or business that purchases residential real estate).The drop in purchases has brought the total number of homes bought by investors below pre-pandemic levels, which is a major concern for a market where investors remained the last remaining support pillar now that most average Americans seeking to buy their first home are simply unable to afford it and are stuck renting indefinitely.Real estate investors bought roughly 50,000 U.S. homes in the second quarter, the fewest of any second quarter in seven years, with the exception of the start of the pandemic."

knowledge, experience and savviness are all huge pillars of success that many times good partners also bring to the table.good luck...
