@Eugene BrownTo expand your property portfolio, leverage equity or savings, explore multi-unit and single-family properties, and consider the BRRRR Strategy.

Could be a new roof, HVAC system, or new kitchen along the way (all of which could certainly add equity to the home irrespective of the year it was built).  

I would look into multi family or doing BRRR's.

When I had a secondary structure demolished a few years ago, I did discover the lot was zoned that I could rebuild another multi-family building on the lot if I wanted to.

I really do appreciate all of the comments folks have made and it’s clear that they have systems in place and I hope that knowledge will aid me in my endeavor.
