Before you offer, before you sign

Ask for 3 years of trading accounts and booking data

The property is already operated as a guesthouse. Real occupancy, ADR and cost lines beat any model you or an AI can build.

Who: You / your accountant

Establish why they are selling and how long it has been listed

Price already fell from €2.52M to €2.205M. Time on market is your strongest negotiating lever.

Who: You

Check classé / inscrit Monument Historique status and any 500 m perimeter

Determines who can do the works, the cost, permit lead times — but also potential grants and tax deductions.

Who: Mairie / DRAC Nouvelle-Aquitaine

Obtain the airfield authorisation document and check transferability

If the aerodrome permission is personal to the current owner or lapses on sale, a core part of your business case evaporates.

Who: DGAC / DSAC Ouest

Request a certificat d'urbanisme for planned conversions

Confirms in writing that outbuildings can become guest accommodation or an event space before you commit.

Who: Mairie de Pierrefitte

Ask whether any land is under a bail rural

A farm lease on the meadows is nearly impossible to terminate and reduces both usability and value.

Who: Notaire

Get a preliminary view on ERP classification for your intended use

Fire and accessibility compliance can cost €50k–€200k and is the most commonly underestimated item.

Who: Bureau de contrôle (Apave/Socotec)

Pull the Géorisques report

Flood, clay shrink-swell, radon and seismic exposure — relevant with moats and ponds on site.

Who: georisques.gouv.fr

Damp and salt damage on all moat-facing walls

The single most expensive chronic problem in a moated château. Look at skirting height, basements and the ground floor of the towers.

Verify 'roof redone' — date, contractor, guarantee, and which buildings

A decennale guarantee that transfers to you is worth real money; a partial job is not the same as a full re-roof.

Who: Ask for invoices and the décennale certificate

Roof timbers, floors and beams: rot, deathwatch beetle, capricorn

Standard in western France; treatment across 750 m² is expensive.

Who: Charpentier / traitement specialist

Electrical installation and its capacity for commercial use

Rewiring a château to ERP standard is a €60k–€150k item and is rarely visible on a viewing.

Boiler age, oil tank compliance and cost of converting away from oil

Price the biomass/heat-pump option now; it changes both running costs and DPE-driven resale value.

Moat walls, bridges, pontoon and sluice

Bank collapse and bridge repairs are structural works on heritage masonry — €50k+ each.

Septic system: exact upgrade specification and cost for commercial capacity

The brochure says 'to be upgraded'. A commercial-capacity system for 20+ guests is a very different price from a domestic one.

Who: SPANC (local sanitation authority)

Chapel structural condition and roof

'Awaiting restoration' can mean €40k or €400k. Get it quantified before exchange.

Outbuildings: walls, roofs, floors and whether conversion is realistic

500 m² of ruin is a liability; 500 m² of sound shell is your future revenue. Very different assets.

Runway surface, drainage, obstacle clearance and approach

A soft runway after rain kills the fly-in proposition for half the year.

Fibre/mobile coverage and three-phase power

Seminars and remote-work retreats are impossible without reliable connectivity; workshops need three-phase.

Decide the ownership vehicle (personal, SCI, SARL de famille) before the compromis

Determines income tax treatment, VAT recovery on works, succession and whether you can deduct operating losses.

Who: Notaire + French tax adviser

Check VAT recovery on renovation if you run classified tourism accommodation

With hotel-like services (breakfast, linen, reception) you can be VAT-registered and recover 20% on works — often €50k–€150k.

Insert suspensive conditions: financing, urbanisme, airfield authorisation, survey

These are the only free exits you will get. Write the airfield one explicitly — it is not standard.

Review the full diagnostics pack (DPE, asbestos, lead, termites, electrics, gas, ERP risk)

Legally mandatory and often reveals items the brochure omits.

Verify boundaries, servitudes and rights of way over the 54 ha

Farm access, hunting rights (droit de chasse) and utility easements can constrain events and privacy.

Check hunting rights and ACCA membership on the woodland

In some communes you cannot exclude hunters from your own forest without formal opposition.

Get a real insurance quote for the intended commercial + aviation use before exchange

Occasionally uninsurable or surprisingly expensive; better to know now.

Explore heritage grants and Fondation du Patrimoine / DRAC aid for the chapel

Can cover 20–40% of eligible restoration on protected elements and unlocks the label for tax deductions.

Present the offer as a costed dossier, not a number

List septic, chapel, outbuildings, glazing, ERP, heating conversion with quotes. A justified €1.78M reads as serious; an unexplained one reads as insulting.

Negotiate the 5% agency commission explicitly

€105k of the €2.205M is commission. Buyer-paid fees are negotiable, especially after a long marketing period.

Negotiate furniture, equipment and the aircraft-related kit into the price

A furnished château is worth €50k–€150k in fit-out you would otherwise have to buy, and it makes the operation turnkey.

Ask for the trading goodwill: website, bookings, reviews, brand

bournizeaux.com, existing forward bookings and reviews have real value and are usually forgotten in the deal.

Ask for a handover period with the current owners

Three months of overlap on operations, suppliers, staff and the airfield is worth more than a small price concession.

Use winter as leverage

Rural French châteaux are hardest to sell between November and February. Offers made then land better.
