Neighborhoods
Where we know every street
We work six neighborhoods deeply instead of sixty thinly. Ask us which block gets the morning light — we can tell you.
Harbor Hills
Craftsman streets stepping down to the water, two farmers markets and the city’s best sunset commute on the No. 6 ferry.
Foundry District
Converted lofts and canal-side workshops where the ceilings are tall, the coffee is serious and the walk score is 96.
Alder Park
Grand crescents around forty acres of oaks — quiet, leafy and five minutes from the two best schools in the county.
How buying works
From first call to front door in four moves
01
Consult
One unhurried conversation about budget, timing and the life the address needs to hold. No sign-up, no pressure.
02
Curate
A hand-picked shortlist from listed and off-market homes — never more than seven, each one worth your Saturday.
03
Tour
Private viewings scheduled around your week, with honest notes on every property — including the ones we’d pass on.
04
Close
Negotiation, inspection and escrow managed to the day. You get the keys — the paperwork stays our problem.
The team
Brokers who answer their own phones
Three licensed brokers, no hand-offs. The person who tours the home with you is the person who negotiates it.
Client stories
Trusted with the biggest move people make
“Keystone showed us four homes. The second one was ours. Eleven days from first call to accepted offer — and they negotiated $40,000 under asking in a sellers’ market.”
Priya & Daniel Mehta
Bought in Harbor Hills, 2025
“They staged, photographed and listed our house in nine days, then held their nerve through three rounds of offers. We closed at 104% of asking — to a family we actually like.”
Robert Ellison
Sold in Old Grove, 2026
Thinking of selling
What is your home worth in today’s market?
