Hi, my name is

Aaron Rumery

And I'm a Staff Software Engineer & Multifamily Investor

{ "description": "For more than a decade I've been a software engineer building fault-tolerant systems. I also invest in and operate multifamily across New Hampshire. " }

About me

Production systems taught me to care most about who owns the outcome when something breaks. I would rather find the weak points on paper than in an outage. Real estate rewards the same instinct, so I run the numbers myself and only buy what I would be glad to own for years.

// Real Estate

Through Trinity North Capital, I buy multifamily across New Hampshire and the Upper Valley, a market where housing demand has outpaced new supply for nearly twenty years.

{
"focus": "Typically 8 to 50 units, held for the long term.",
"thesis": "Anchor employers like Dartmouth Health, Dartmouth College, and Plymouth State keep demand steady, while zoning and supply constraints keep new building scarce. These deals are too small for institutions and too large for most local buyers, and that gap is the one we pursue.",
"approach": "Preserve capital first. Underwrite conservatively. Co-invest on every deal. Report honestly whether the news is good or bad."
