What your summers as a renter already told you about buying here

Buying + Selling

People who have rented the same two weeks here for a decade apologize for not knowing the market. They have it backwards — they know the part that is hardest to acquire any other way.

You already know more than most buyers

A good number of the people I help buy here have been coming for years. Not as tourists. As renters — the same two weeks in July, or the whole of August, or a shoulder-season fortnight they have quietly guarded on the calendar for a decade.

By the time they call me, they apologize for not knowing the market. They have it backwards. They know something the market cannot tell them, and it is the part that is hardest to acquire any other way.

What they do not yet know is which of their knowledge transfers to ownership, and which of it was the lease doing the work.

What a lease teaches that no showing can

A showing is forty-five minutes on a Tuesday in good weather. A summer is different, and it teaches things I could not tell you in a walkthrough even if I wanted to.

You know how long it actually takes to get from that house to the beach you like, with a cooler and children and a bicycle, in August, when the whole island is doing the same thing. That is a lived number, not a drive-time estimate.

You know what the house sounds like. Whether the road carries traffic at seven in the morning. Whether the kitchen works when there are nine of you. Whether the outdoor shower gets sun. Whether the light comes into the room you would want to read in, and at what hour.

You know your own rhythm here — whether you are a walk-to-dinner household or a pack-the-car household, whether you use the water every day or once a week, whether you want to be in the middle of things or twenty minutes from them. Most buyers are guessing at this. You have tested it, repeatedly, with your actual family.

That is genuine due diligence, and I treat it as such. When a client tells me they have rented the same stretch of the island for eight summers, I stop asking them what they think they want and start asking what they noticed.

What the lease was quietly handling

Here is the part that catches people, and it catches almost everyone.

Everything that broke was someone else’s phone call. The heat that would not come on in June, the well pump, the outdoor shower that needed rebuilding after a hard winter, the roof after a February northeaster — all of it happened, and none of it reached you. You arrived to a house that worked.

Renting is a filtered experience of a property by design. You are shown the house at its best because that is what you paid for. Ownership hands you the other nine months, the ones you have never seen, and the systems that carry the house through them.

So the questions change. Not “do I love this house” — you have answered that more thoroughly than most buyers ever do. The new questions are about the house’s spine. What is the septic situation, and what bedroom count does it legally support. Is it on town water or a private well. What does the insurance actually cost, not what did someone estimate. What has the shoreline done, if you are near one. What did the HDC approve, and does it match what is standing.

None of that shows up in eight excellent Augusts. I have written the diligence side of it in the island home inspection guide and what it costs to own here.

The nine months you have never met

If your entire experience of Nantucket is July and August, you have met the island at full volume and nowhere else.

I do not say that as a warning. Plenty of owners will tell you the other seasons are the better ones — the island after the boats thin out has its own case, and I made it in the off-season guide. October opens scallop season. December belongs to Stroll. There is a version of this place that summer renters simply never encounter, and a fair number of people end up preferring it.

But it is a real question, not a rhetorical one, and it deserves an honest answer before you buy rather than after. Will you come in November? Genuinely? Some families do and it changes what the house is for. Some do not, and that is fine too — it just means the house is a summer instrument, and it should be chosen and budgeted as one.

There is also the weather side of ownership, which a renter is structurally insulated from. September and October are the busy end of the Atlantic season, and an owned house has a plan for that; a rented one had someone else’s. I set out what that looks like in what owners do when the forecast turns and caretaking when you are away.

The house you rented is not necessarily the house to buy

This is the conversation I have most often with renters, and it is the one worth having early.

People arrive wanting the house they have rented, or its twin. Sometimes that is exactly right. Often it is not, for a reason that has nothing to do with the house: a rental is chosen for a fortnight, and ownership is chosen for a decade.

The house that was perfect for two weeks with a full complement of guests may be more house than you want for the other fifty. The location that was ideal when the whole point was proximity to the beach may matter less than proximity to town once you are here in the shoulder seasons. The layout that worked when everyone was young works differently later.

And there is a practical matter. Renting a house repeatedly gives you affection for it. It does not give you a claim on it. If it is not for sale, it is not for sale — and the owner has probably been asked before, sometimes clumsily. If you genuinely want to open that conversation, it is worth doing properly and quietly, through someone who knows how to make an approach that does not sour a relationship you may still want next July. That is a real service and I am happy to do it. It is also a long shot, and I will tell you so honestly rather than let you organize a search around a house that may never trade.

What I would do with your rental history

If you have been coming here for years, the first thing I want is not a wish list. It is the history.

Which houses, which parts of the island, which weeks, across how many summers. What you did every single day, and what you thought you would do and never did. What you complained about by the third day. What you found yourself defending to friends. Which drive annoyed you. Which morning you remember.

From that I can usually tell you more about what you should own than a questionnaire ever would — including, sometimes, that the part of the island you have been renting in is not where the right house for you is going to be, for reasons about the property and how you actually live, and that the search should widen.

That is the advantage renters have. Everyone else is buying a hypothesis. You are buying something you have already tested. The work is separating what you tested from what the lease was carrying for you.

If you have been renting here for years and are starting to wonder what owning would actually ask of you, that is a good conversation and an early one. I am glad to have it with no timeline attached.
