It is my view it has the exact opposite correlation that most people think. 

Total number of people in the 4 plex is 6. 

Most people think real estate investing requires huge capital, perfect credit, or bank loans—but that’s not always true.

You should have an open conversation with as many people as you can find.

The people the seller should have this discussion with is the title company and or legal counsel.  

Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – so, they often select the first PMC they call or that calls them back!

if you buy a random property on Zillow and turn it over to people you have never met, you will very likely lose money, get frustrated, and set yourself back.if you're serious i'd pick a market and plan on making several trips there. 

Another thing to add is the regulations, HOAs and Cities are imposing a lot of regulation on short-term rentals or rent by a room, I have seen some HOAs regulate the amount of people authorized to rent the property too.It requires to do a lot of due dilligence to begin with mainly in such big house. 

When we were selling, people loved the "aged" look, and it was a big selling point for that house.

For example over the last four to five years a lot of people went out and bought STRs thinking it was going to be a great investment only to find out that the numbers did not work a year later and needed to try to use it as a LTR to make ends meet.
