Worth a look
Only listings that clear your current screen.
No current listings clear this screen. New matches will appear here automatically once a source is connected.
Property intelligence should lead to a decision, not another spreadsheet.
Realize brings the work that normally lives across listings, records, comps, rental research, maps, and rough budgets into one clear property thesis.
The few things that actually change a deal.
An investment thesis
A direct read on the property at its current ask: pursue, pass, or investigate further.
Potential, priced honestly
The paths that could create value, with early cost ranges, finished-value screens, and clear assumptions.
Evidence and next actions
The source behind each claim, the records still needed, and the single best next step.
How we treat the information
Potential is not value until the evidence supports it.
Reported Listing and public-record facts we can trace.
Modeled Cost, rent, and value screens that make assumptions visible.
Needs proof The survey, permit, septic, or comp that can change the answer.
A current lead, an owner story, and a finished benchmark.
Current opportunity · Sag Harbor Village
51 Garden Street
Good location and possible upside, but the records and rental math need to clear before the ask makes sense.
Owner case · East Hampton
124 Springy Banks Road
Actual rental history, recent systems work, and a septic plan show how patient upgrades can create long-term optionality.
Finished benchmark · Northwest Harbor
27 Rivers Road
A clear example of the complete rental product: bedrooms, pool, privacy, presentation, and a strong seasonal operating case.
Starting with the East End
Local detail is the product.
Septic capacity, pool placement, wetlands, historic review, seasonal rental demand, and finished-home precedent can all change a decision. Realize begins where those details matter most.
Understand a property’s future before you commit to its present.

Verdict
Negotiate hard or pass.
Great village location. The price already assumes renovation and legal upside that the records do not prove yet.
- Asking
- $2.50M
- Price to test
- $2.00M–$2.30M
- Renovation
- $300K–$450K
Three facts drive the decision.
Best path
Renovate only after the records are in.
First prove the existing pool, garage, bedroom count, and sanitary capacity. Then price a focused renovation against finished village comps.
- Finished-value screen
- $2.9M–$3.5M+
- Seasonal rent screen
- $70K–$95K/yr
Do these three things.
- 1Pull the Village fileCO, permits, sanitary approval, and historic review.
- 2Get the signed surveyConfirm setbacks, coverage, pool, and garage status.
- 3Price the renovationGet two or three contractor quotes before setting the offer.

What could change the outcome.
Realize starts with the handful of facts that change whether a property is worth pursuing.
Three things are worth proving.
These are the few questions that could materially improve or weaken the thesis.
Worth pursuing after one record check.
The lot is underbuilt and the pool is already in place. At this price, the deal works only if the existing home can support a stronger legal bedroom program.
Recommended move

What could block the plan.
The sanitary approval controls the dependable bedroom count, not the listing.
Wastewater, environmental overlays, the water source, and the legal property record are the largest open questions.

Cheap primary debt, expensive flexible debt.

The septic upgrade is the optionality project.
Bathrooms improve rentability. The IA septic sized for 6–7 bedrooms could expand the legal future program.

Five ways to play it from here
We bought a dated East Hampton property with a pool and clear potential, improved it in stages, generated meaningful summer rental income, and now need to decide whether to stop after the bathrooms and septic, add bedrooms, expand, or sell with documented upside.
