Homes, rentals, and commercial — all in Berrien County.
I’m Alex — a Berrien County REALTOR® who buys and holds rentals myself, runs a commercial sales dashboard pulled straight from the MLS, and keeps an ordinance-by-ordinance rental guide for all 39 municipalities in the county. If you’re buying a home, selling a home, or trying to figure out whether a property actually pencils out, you’re in the right place.
No commitment • No pressure • Free market analysis
Three lanes, one phone number.
Most of my work is residential. Commercial and rentals are where I go deeper than most agents in the area — because I own rentals myself and built the data tools I wanted to see.
Residential
Buyers and sellers across Berrien County — from first homes to move-up, move-down, or investment purchases.
- Fiduciary buyer representation — not dual agency
- Comparative market analysis before you list or offer
- I preview homes weekly and flag what listings don’t show
Commercial
Retail, office, industrial, and business opportunity sales across the county — pricing backed by MLS data I track myself.
- 354 commercial sales · 72 leases in the county dataset
- Price / sqft, DOM, and financing patterns by year and city
- Straight-up conversations about what a building is actually worth
Rentals & Investment
I own rentals in Berrien County and help other owners — and would-be owners — figure out where the real deals are and where the ordinances will bite.
- STR rules vary by township — I track all 39
- Honest pricing analysis (no “it’ll cash-flow” fantasies)
- Connected to lenders, inspectors, contractors, title
Resources I’ve built and use on real deals.
These aren’t one-pagers. They’re the tools I lean on when I’m writing an offer, pricing a listing, or sizing up a rental — and they’re on the site for anyone else who’d find them useful.

01
Discipline & attention to detail — from the Navy
Service built habits that don’t go away: follow-through on checklists, doubling back to confirm the thing everyone assumed was fine, and writing things down.

02
Listening first — from being a medic
Medic work is mostly listening. What hurts, when it started, what made it worse. That’s how I run a buyer or seller consult too — before I talk about strategy, I want to understand what you’re actually trying to do.

03
Patience & kindness — from raising a family
Real estate moves people through one of the biggest decisions of their life. That deserves patience, not a sales pitch. My wife Elizabeth is a nurse; our daughters Charlotte and Zoey keep us grounded.

Local connections that matter
Inspectors, lenders, contractors, title, roofers, HVAC, real-estate attorneys — I have people I’ve personally used. When someone on my list drops the ball, I take them off. That’s what “vetted” actually means.

Straight-up analysis — not a sales pitch
I’d rather walk you out of more homes than into them if something’s off. If comps say $415K and the list is $440K, I’ll say so. If the township just capped STRs, you’ll hear about it before you write the offer.
In their words.
“I have worked with a lot of RE agents over the years and have never seen an agent be more truly hands on! If you are serious about selling a local property at or above the fair market value then don’t hesitate and call Alex.”
“If I decide to sell my home in the future I will certainly be using him again. I highly recommend him to anyone interested in buying or selling their house.”
“If you need a smart & aggressive real estate agent… that is willing to roll up their sleeves and get to work then get Alexander Zeisberg on your TEAM.”

My wife Elizabeth is a dedicated nurse. Together we’re hands-on parents to our daughters Charlotte and Zoey — Charlotte loves every art form she can find, from drawing to dancing; Zoey’s fearless energy keeps us on our toes.
After serving in the military and living around the country, I’ve come to value community and family. Outside of work you’ll find us on Lake Michigan, hiking the sand dunes, or working on a house project.
For us, life is about growth, resilience, and making a positive impact. That carries over into how I show up for clients.
