Most property owners think developers are just looking at location. They're not. Not exactly.
Location matters, obviously. But when we evaluate a property — and we evaluate most submissions within 48 hours — we're running through a specific mental framework before we even drive out to look. It has a formal name in appraisal and development circles: highest and best use analysis. Most people have never heard of it. Most people who own shore properties have no idea it applies to what they're sitting on.
So let me break it down the way we actually work through it.
What "Highest and Best Use" Actually Means
The phrase sounds like jargon. It is jargon. But the underlying logic is simple.
A property's value isn't determined solely by what exists on it today. It's determined by what the land could support — legally, physically, and financially — relative to what it currently does. A 1950s single-story cottage on a 40-by-100 lot in a zone that permits three-story construction isn't just a cottage. It's a development opportunity wearing a cottage.
That gap — between current use and highest potential use — is where development value lives.
Four questions drive the analysis. Every developer worth working with is thinking through all four, whether they say it out loud or not.
Is it legally permissible? Zoning tells us what we can build. Setbacks, height restrictions, lot coverage, the permitted number of units — these are the hard constraints. A lot that looks generous on a map can lose forty percent of its buildable footprint once you account for side yard setbacks and impervious coverage limits.
Is it physically possible? Lot dimensions, shape, grade, elevation. A narrow 25-foot-wide lot has a fundamentally different physical reality than a 50-foot lot on the same block. Base flood elevation matters enormously here — properties that require significant elevation to meet current FEMA standards change the construction math considerably.
Is it financially feasible? This is where most owner assumptions break down. A property might be legally permissible to redevelop and physically suited for it, but if comparable finished homes in that specific micro-market won't support the numbers, the economics don't work. Not every shore block is the same block.
What's the maximally productive use? Given the first three answers, what configuration produces the best outcome? Sometimes that's a large single-family home. Sometimes it's a duplex where zoning and market both support it. Sometimes — and this is the inconvenient truth — the existing structure has enough bones that a gut renovation outperforms a tear-down.
Where Most Owner Valuations Go Wrong
Here's the thing nobody wants to say directly: owners almost always overestimate renovation value and underestimate land value. At the same time.
They hold onto the house because they assume the house itself is worth something to a developer. Usually it isn't. What's worth something is the land under it and the zoning envelope above it. The structure is frequently a cost, not an asset — demolition, asbestos abatement if it's old enough, haul-off.
(This is not universal. A solidly built 1980s home in genuinely good condition on a less valuable lot might be worth preserving and updating. Context matters and we don't approach every submission the same way.)
The overestimation of renovation value runs the other direction. Owners see what renovated homes sell for on their block and assume a cosmetic refresh gets them close. It rarely does. Buyers at the shore — especially in the price ranges where new construction competes — have been conditioned to expect certain things. Engineered hardwood. Quartz countertops. Epoxy grout in wet areas so the tile field stays clean through years of beach use. These aren't luxury upgrades anymore; they're baseline expectations. Catching an aged structure up to that baseline costs more than most owners project. The real numbers on that process) are worth understanding before assuming renovation is the cheaper path.
The other underestimation: what carrying costs do to a marginal decision. If a property is in an insurance-challenged position — and a lot of older shore homes increasingly are, given what's happened to premiums — every month of delay has a real cost. Shore home insurance in 2026 has changed the holding calculus in ways that weren't true even five years ago.
How We Actually Work Through It at Redfern
We've been doing this for 40+ years. Family-owned, 150+ builds. Jim Colahan, our founder and managing partner, personally coordinates every project — which means the evaluation isn't being handed off to a junior analyst who's never driven the block.
When a submission comes in, we're looking at lot dimensions and zoning simultaneously. We're pulling recent comparable sales, but we're being specific about which comps actually apply — a new construction sale two blocks from the beach doesn't tell you much about a lot that backs to a canal. Micro-location matters at the shore in ways that broader market averages obscure.
We're also thinking about the project timeline honestly. From demolition to sale-ready, we're typically looking at approximately six months. That's not a promise that every project lands in six months — permitting, weather, and supply chain can all stretch a timeline. But it's a realistic working assumption, not a wishful one.
For owners who want to stay involved in the upside rather than just sell outright, we structure joint ventures. Typically 25% to 50% of net profit, structured per deal based on the specifics of the land, the scope, and the risk each party is carrying. The philosophy behind why JVs work the way they do is worth reading if you're trying to understand whether that structure makes sense for your situation. And there are tax angles that come into play in a JV that almost nobody brings up during the initial conversation — that piece covers it without the usual glossing over.
The honest version of our evaluation: we're not going to tell you a property pencils when it doesn't. We've passed on properties that looked interesting on paper because the zoning reality didn't support what we'd need to build, or because the comparable sales suggested a ceiling that the project costs couldn't justify. A quick evaluation that leads to a no is still useful information — it tells you something about what you actually have.
The most common mistake owners make with aged shore homes is waiting too long to understand which bucket their property falls into. Not every old shore home is a development opportunity. But some of them are sitting on significant latent value that the current structure is obscuring.

Take a typical mid-century ranch on a standard lot in a zone that allows three-story construction. Nothing dramatic about it. The kind of place that's been in a family for decades, maybe rented seasonally, never quite updated enough to command real rental rates. From the street, it looks like just another aging shore property. From a development standpoint, that zoning envelope is what makes it interesting — the question is whether the comparable sales ceiling on that specific block justifies the full construction and carrying cost of what could go there.
Sometimes the answer is yes. Sometimes it's not yet but getting closer as values creep up. Sometimes the land is the valuable part regardless of timing, and the family is better served understanding that now than discovering it in five years after another round of deferred maintenance.
What's sitting on your lot right now — and what does the zoning say could be there instead?
