The Bottom Line (Quick Answer)

Before buying rural acreage near London or in Elgin County, make three checks a condition of your offer: the well (flow-rate + water quality), the septic (age, last pump-out, bed location), and a WETT inspection on any wood-burning appliance.
Skip them and a “dream property” becomes a five-figure money pit — a failed septic bed or a weak well are the classic rural surprises.
The Ken Small Real Estate Team hands rural buyers this exact checklist so they buy the land and the workshop with their eyes open.

City homes hide their problems behind drywall. Rural properties hide theirs underground and in the outbuildings. Here’s the honest checklist — the questions most buyers forget until it’s too late — so you buy acreage, not a money pit.

1. The well — what do I ask for?

Ask for the well record, a recent flow-rate test, and a potability (water quality) test. Ontario keeps well records on file — you can look up a property’s record on the province’s Well Records map, and the “Wells on your property” guide explains your obligations as an owner. A weak or contaminated well is expensive and disruptive to fix. No test, no offer — make it a condition.

2. The septic — where’s the trap?

Find out the age, the last pump-out date, and where the bed actually is. A failed septic bed is a five-figure replacement. Septic (on-site sewage) permits and records are handled locally — confirm through the Municipality of Dutton Dunwich building department. And if you’re planning a second unit, septic capacity is the gatekeeper — see what RS zoning actually lets you build before you count on it. A quick inspection during your conditional period is cheap insurance.

3. Heat & hydro — what’s different rurally?

Rural often means no natural gas. Check the furnace/heat-source age and efficiency (a newer heat pump, like the 2025 unit at 29159 Lakeview, is a big plus), the panel amperage, and whether the shop has its own service. Dual 200-amp is serious power for a workshop.

4. The WETT inspection — why does my insurer care?

If there’s a wood-burning fireplace or stove, most insurers will want a WETT inspection (Wood Energy Technology Transfer) — here’s what a WETT inspection is, and you can find a certified professional through WETT Inc. It confirms the appliance is installed and functioning safely. Get it early — a clean certificate is a trust asset; a surprise finding during conditions can stall a deal. If a fireplace is sold “as-is,” factor that in.

5. Access & the shops — is it legal?

Confirm road maintenance and year-round access, and check that outbuildings are permitted and legally used — that a structure exists is not proof it’s legal.

The rural due-diligence checklist

Check	Ask for	Why it matters
Well	Well record, flow-rate, potability test	Water you can’t drink or run is a deal-breaker.
Septic	Age, last pump-out, bed location, inspection	A failed bed is a five-figure fix.
Heat / hydro	Heat-source age, panel amps, shop service	No gas rurally; power runs the shop.
WETT	Certificate on any wood appliance	Your insurer will require it.
Access / shops	Road maintenance, permits on outbuildings	“It exists” is not “it’s legal.”

Pro Tip:

Write the well, septic and WETT checks into your offer as conditions — not a friendly “we’ll look later.” Conditions give you a clean exit if something fails. A seller who has already done them (and hands you the paperwork) is telling you something good.

A live example

29159 Lakeview Line in Wallacetown puts this checklist to work — a 2025 heat pump, dual 200-amp service, a heated workshop, and a full document binder so you can do this due diligence up front. See the full listing and the rural buyer’s guide.

Who should NOT waive these conditions

Straight talk: if you’re tempted to skip the well test to win a bidding war, don’t — water is the one thing you can’t negotiate after closing. If the septic age is unknown and the bed location is a mystery, that is not the property to waive conditions on. And if there’s a wood stove with no WETT certificate and you haven’t confirmed your insurer will bind, slow down. Rural rewards the prepared, not the fast.

Frequently asked questions

What is a WETT inspection? A safety check of wood-burning appliances that most insurers require in rural homes.

How much is a septic replacement? Typically five figures — which is why age and condition matter before you buy.

Should I test the well? Always — flow-rate and potability, as a condition of your offer.
