Price History: What Homes Here Have Actually Sold For
Median sale price over the trailing 12 months ending August 2 of each year, from record-level Stellar MLS closed sales. Same methodology as every appreciation figure on this page: the 2026 point ($1.65M) IS the median in the snapshot above, and the move from 2025 ($1.80M) IS the -8.3% one-year change.
Windows contain 0 to 3 sales each (3 in the current window); every figure carries its sample size, and thin markets swing on single closings. Based on Stellar MLS data distributed by MLS GRID for the period 2010 through 2026. Deemed reliable but not guaranteed.

The Sanctuary buying strategy.
If we were buying in Sanctuary today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in Sanctuary.
A closer look at the Sanctuary market
At a median of $905 per square foot, Sanctuary prices sit in a fairly defined band, so condition and updates — more than the list price — tend to separate one home from the next.
The trailing-12-month median down 8% year over year. Homes that do trade take a median 18 days on market, useful leverage on any listing that has lingered.
The location and the amenities are priced into every listing in Sanctuary. The deal is won or lost on condition, the comps, and the renovation math.

Momentum Intelligence Scores are our proprietary, qualitative assessment on a 0 to 10 scale, built from the record-level market data on this page. They are a framework for comparing communities, not a guarantee of future value and not advice on a specific home; unlike an automated value estimate they do not price your home, they grade the community on evidence you can inspect. Composite is the plain average of the 3 factors (3.3). Basis: Recent Direction -8.3% year-over-year; Owner Commitment 0% owner-occupied; Pricing Power 93.9% sale-to-list. Refreshed with each data update.
