Why would a $400,000 cottage in Eagles Mere cost more to carry, year after year, than a $400,000 farmhouse forty minutes away in the same county? Anyone comparing listings across Sullivan County eventually runs into this question, and the portals never answer it. They show purchase price. They don't show what happens after closing.
Sullivan County has some of the lowest home values in Pennsylvania. Yet the borough of Eagles Mere, sitting inside that same low-cost county, carries the highest property tax bill of any municipality in it. That looks backward until you understand who is actually paying for the borough's roads, fire company, and water system, and how few of them there are.
A Borough of 120 People Carrying a Resort-Sized Bill
Eagles Mere Borough has 120 full-time residents. During the summer, according to the borough's own site, that number climbs past 3,000. The roads still need plowing in February, the fire company still needs funding in every month of the year, and the borough's costs get divided across a permanent tax base that is, structurally, tiny.
At the same time, the properties inside that tax base are valuable. Eagles Mere's housing stock is dominated by century-old Shingle-style and Queen Anne cottages built for wealthy families from Philadelphia and New York, and those assessed values don't shrink just because the owner only lives there ten weeks a year. The result is a tax bill built to fund a small year-round town, spread across a seasonal-cottage tax base that carries real value on the county's books.
County-level assessment data compiled in 2026 puts Sullivan County's median annual property tax bill at $1,694, with a low of $894 in Lopez. Eagles Mere sits at the opposite end of that same county, with a median bill reported between roughly $4,700 and just over $5,000 depending on which assessment year is measured. Even at the conservative end, that's nearly three times what a homeowner in most of the rest of the county pays. Eagles Mere's own tax figures put the effective rate at 1.21%, higher than the national median of 1.02% but still below the Pennsylvania state median of 2.81%.
Here's the county picture side by side:
| Location | Median annual tax bill | What it tells a buyer |
|---|---|---|
| Lopez, Sullivan County | $894 | Lowest carrying cost in the county |
| Sullivan County (overall median) | $1,694 | Baseline for comparison shopping |
| Eagles Mere | ~$4,700 to $5,066 | Highest carrying cost in the county, by a wide margin |
A buyer weighing two similarly priced homes in Sullivan County, one in Eagles Mere and one outside it, is not comparing two equivalent monthly payments. The difference shows up every year on the tax bill, not on the closing disclosure.
The Line Item That Never Makes the Listing Photos
Property taxes aren't the only recurring cost unique to owning here. Eagles Mere Lake and its shoreline are privately owned and managed by the Eagles Mere Association, a nonprofit formed by property owners in 1961. Membership isn't automatic just because you close on a house. Buyers who purchase an improved property in the borough apply for membership, and new owners typically start as Associate Type II members, a category the association's own rules say lasts a minimum of two years and until a full share becomes available.
That means the lake access a buyer may be picturing on day one of ownership can, in practice, take longer to arrive in full. Members are billed annually for dues and lake protection fees on top of that. Even renters aren't exempt: anyone staying in a home they don't own needs a temporary membership to use the beach or borrow a boat, with recent seasonal listings quoting fees in the range of a couple hundred dollars per stay.
None of this appears in a listing description. It shows up after the offer is accepted, when the buyer starts filling out the association paperwork and realizes the lake they bought a house to be near isn't quite theirs yet, not fully, not on day one.
What "Historic District" Actually Means Here
There's a second assumption that trips up buyers comparing Eagles Mere to other towns, and it cuts the opposite direction from the tax bill. Eagles Mere Village has been listed on the National Register of Historic Places since 1996, covering 234 contributing buildings, mostly turn-of-the-century cottages, boat houses, and a handful of commercial landmarks in the village center. Buyers often read that designation and assume it means the house is frozen: no additions, no altered rooflines, nothing that changes the exterior a preservation board once approved.
That's not the story the town tells about itself. The Eagles Mere Museum runs a recurring house tour called "Everything Old is New Again," built specifically to showcase how much these cottages have changed since the 1880s. Porches have been enclosed and reopened. Dormers have been added. Rooflines have been altered, siding swapped, entire additions built onto structures that started out half their current size. The district's own building records show both directions of that tradition: the Munson Cottage on Eagles Mere Avenue picked up 1960s aluminum cladding over its original wood shingle, while the owners of the Hartley Cottage, also on Eagles Mere Avenue, later removed a 1960s addition to bring the house closer to its original form.
The takeaway for a buyer isn't that anything goes. Local permitting still applies, and anyone planning exterior work should confirm requirements with the borough before assuming what's allowed. The takeaway is that a National Register listing here has coexisted with continuous, visible renovation for well over a century. A cottage that needs work isn't automatically a cottage you can't touch.
Running the Real Numbers Before You Write an Offer
Put the tax mechanism and the renovation tradition together and the comparison shopping gets clearer. The sale price on a Eagles Mere listing tells you less than it would in most towns, in both directions. It understates the ongoing cost of ownership, because the tax bill and association dues sit outside it. And it can overstate the risk of buying an older cottage, because the fear that historic status blocks renovation doesn't match what's actually happened here for 140 years.
Before comparing an Eagles Mere listing to something else in the county, it's worth pulling a few numbers that a price alone won't surface:
- The current assessed value and most recent tax bill for the specific parcel, not just the county or borough median
- Whether Eagles Mere Association membership transfers with the sale, or whether the buyer starts as a new Associate Type II member subject to the waiting period
- Whether the cottage is winterized for year-round living, which we've covered in more detail in our guide to what living in Eagles Mere is actually like
- Any borough permitting requirements for planned exterior work, confirmed directly rather than assumed from the historic designation alone
None of these show up in a search filter. They show up in a conversation with someone who knows which questions to ask before an offer goes in, not after.
A Few Common Questions
Does buying a home in Eagles Mere include automatic lake access? Not immediately in full. New owners typically apply for Eagles Mere Association membership and start in a category that lasts a minimum of two years before full membership, including a share, becomes available.
Will the historic district status stop me from renovating? Historically, no. Cottages throughout the district have been altered continuously since the 1880s, a tradition the Eagles Mere Museum documents through its own house tours. Buyers planning exterior changes should still confirm current permitting requirements with the borough.
Why is Eagles Mere's tax bill so much higher than the rest of Sullivan County? The borough has only 120 full-time residents according to its own figures, so the cost of local services gets divided across a small permanent population, even though the tax base includes a large number of valuable seasonal cottages.
Comparing towns by list price alone will always miss the parts of ownership that only show up after closing.
