Some of the factors may be road congestion, the supply and demand of the product and nearby product, roadway access to major arteries for work (183 is undergoing massive roadway construction,SH 130), schools, etc.

@Michael TaylorLess supply on market when demand stays the same = prices go upIf vaccine takes years to be available (like the flu shot for example) are you willing to stop buying for years because of the unknown?

I wish we respected and valued our skilled tradesmen more to encourage growth in the supply. 

From an avg of 400 Billion or so to a current acct of over 1.6 Trillion.The current M2 (money supply) is at app 18.43 Trillion.

Until now, home-buying demand has remained high relative to a limited supply of homes available for sale.

Also, any accounts you may have with supply houses and vendors would be static. 

My investments are in less dense markets where space is at less of a premium, so the market demands larger units, and the supply side is able to provide at an acceptable price.You say the vacancy is high - why?

I was only interested in the niche initially because I was 1) impressed by the fact that the industry is essentially restricted in supply in perpetuity and 2) the concept of seller financing.

Some zip codes do support the high cash buyer activity with low number of vacant houses meaning that specific area is more desirable because the demand is HIGH but the supply is LOW.

They have administrative work and costs that they incur as well as E&O insurance they need to supply their agents.
