Selling a Home in East Marlborough or New London, PA: Unionville Prices, No Inspection

Neither East Marlborough nor New London runs a resale inspection or use and occupancy permit. The diligence here is private: wells, septic systems, easements, and one genuine trap, East Marlborough splits between two school districts, and the Kennett side pays an earned income tax the Unionville side does not. Willowdale, Unionville village, and the Avon Grove countryside, explained for sellers.

Neither East Marlborough nor New London asks a seller for anything at resale: no inspection, no certificate, no fee. The catch in Unionville country is never municipal. It is the well test, the septic record, the conservation easement, and, in East Marlborough specifically, a school district line that decides whether a household pays an earned income tax at all.

The two-township picture

East Marlborough holds Unionville village, Willowdale, and the horse farms that give the Unionville-Chadds Ford district its postcard. New London, south along Route 896, offers Avon Grove schools and acreage at friendlier numbers, with a municipal tax rate of one mill. Both sell on documentation, because out here the buyer’s inspector is the only inspector.

No inspection, private diligence

  • The file replaces the certificate. A recent well test, a septic pumping record, and permit history on barns and outbuildings answer the questions no township office will ask here.
  • Easements travel with the deed. Conservation easements and Act 319 farmland enrollment carry restrictions and rollback exposure a buyer must understand before attorney review, not after.
  • New London stayed hands-off. The township once studied a U&O ordinance and never adopted it; there is no rental inspection either.

The district line in East Marlborough

Most of the township feeds Unionville-Chadds Ford; a portion feeds Kennett Consolidated, and Kennett levies an earned income tax that neither the township nor UCFSD imposes. The tax bill, not the mailing address, settles which side a house is on.

The Pennsylvania money

Both townships sit at the standard 2% total realty transfer tax, customarily split, so the seller’s half on a $750,000 sale is $7,500. Pennsylvania withholds nothing at settlement, and longtime owners of appreciated Unionville acreage should check their gain against the federal exclusion, $250,000 single and $500,000 married, with a basis file of improvement receipts ready. The home-sale tax guide walks through the math.

Getting started

The Unionville-country order: a free valuation, the well and septic records assembled, the easement map pulled, and the school district confirmed from the tax bill before the listing is written. Nearby, the Unionville townships guide covers Pocopson, Pennsbury, Birmingham, and West Marlborough, the Avon Grove guide the townships around New London, and the Chester County downsizing guide maps where sellers here land next.

East Marlborough and New London seller questions

Do East Marlborough or New London require an inspection to sell?

No. Neither township runs a residential resale inspection or issues a use and occupancy permit at sale. New London researched a U&O ordinance years ago and never adopted one, and East Marlborough states plainly that none is required. There are no municipal certificates, no lateral videos, and no checklists here; the entire diligence burden is private, which in this part of Chester County means wells, septic systems, easements, and the paperwork on horse facilities and accessory buildings.

What is the school district trap in East Marlborough?

The township splits between two districts. Most of East Marlborough, including Unionville village and Willowdale, sits in Unionville-Chadds Ford schools, but a portion lies in Kennett Consolidated. The tax difference is real: neither the township nor Unionville-Chadds Ford imposes an earned income tax, while Kennett Consolidated does, so identical households a road apart can have different paycheck withholding. The township itself has fielded calls from confused residents about it. For a seller, the listing should state the district from the tax bill, not the mailing address; for Unionville-side homes the district is a headline, and for Kennett-side homes clarity up front prevents an attorney-review surprise.

What should sellers in these townships prepare?

The private file that replaces the municipal one. A recent well test and septic pumping record answer the first two questions every buyer’s agent asks out here. Surveys and easement documentation matter on acreage, especially parcels under conservation easement or enrolled in farmland assessment programs like Act 319, where a buyer’s change of use can trigger rollback taxes that belong in the disclosure conversation. Permit history on barns, run-in sheds, and pool fencing rounds it out. None of this is required by the township; all of it is expected by the market.

What is the market like in Unionville and New London?

Two speeds. East Marlborough is the heart of the Unionville-Chadds Ford premium: horse country estates, Willowdale’s planned lanes, and buyers who cross-shop Kennett Square and Pocopson and pay for the district by name. New London runs quieter and more affordable in Avon Grove schools at a municipal rate of one mill, drawing buyers priced out of the UCFSD belt who still want southern Chester County acreage. In both, well-documented properties sell decisively; the ones that stall are the ones where the septic record, the easement map, or the school district turns out to be a surprise.
