Yes — you can sell a house with foundation issues, and in Wagga Wagga it happens all the time. You have four realistic options: fix the problem before listing, diagnose and document it and let buyers price the repair with certainty, sell as-is with a price adjustment, or target the renovator and investor market. Which one puts the most money in your pocket depends on how serious the movement is, what the repair costs, your timeframe, and how the local market is running. The one option that reliably costs sellers money is the fifth, unofficial one: patching over the cracks and hoping the buyer’s building inspector doesn’t notice. They will.
Here’s how to work through the decision properly.
Step one: find out what you’re actually selling
Undiagnosed foundation problems put you in the weakest possible position. Buyers can’t price uncertainty, so they either walk away or discount hard enough to cover the worst case. The fix is information:
- Get a professional foundation inspection, with a structural engineer’s assessment where the movement warrants it. You’ll learn whether you’re dealing with cosmetic seasonal cracking — very common on Wagga’s reactive clay, as our guide to why foundations move in Wagga explains — or genuine structural movement.
- Get an itemised repair quote from a licensed contractor, so the fix has a real number attached instead of a scary unknown.
- Then choose your option with actual figures in front of you.
Plenty of sellers discover at this step that their “foundation problem” is stable, minor cracking that needs a few hundred dollars of proper crack repair and honest documentation — not a structural job at all. Our guide to which cracks matter is a good primer before the inspector arrives.
Your four options compared
| Option | Upfront cost to you | Time before listing | Effect on sale | Best suited to |
|---|---|---|---|---|
| 1. Fix before listing | Full repair cost | Weeks to a couple of months | House sells as a normal home to the full buyer pool | Repairs costing clearly less than the likely buyer discount |
| 2. Diagnose, document, price the fix | Inspection, engineer report, quotes (hundreds to low thousands) | Days to weeks | Buyers can price the issue precisely; discount tends to shrink towards the actual repair cost | Sellers without cash to repair, or where the market is strong |
| 3. Sell as-is, adjust the price | Minimal | Immediate | Reduced buyer pool; discounts often exceed the true repair cost | Urgent sales, deceased estates, houses needing broader renovation |
| 4. Target renovators/investors | Minimal | Immediate | Priced on land and potential rather than condition | Serious structural issues on well-located land |
Option 1: Fix it, then sell
The logic: buyers pay for certainty. A house with documented, engineer-designed, professionally completed underpinning — with the engineering report, contract, licence details and warranty paperwork in a folder on the kitchen bench — usually presents far better than the same house with visible stepped cracking and an unanswered question hanging over it.
This option makes sense when the repair cost is clearly less than the discount buyers would demand. Repair costs are knowable — see our underpinning cost guide for indicative ranges. Two extra points in its favour: in NSW, statutory warranties on residential building work generally run with the property, so their benefit can pass to your buyer (your conveyancer can confirm how this applies to your contract), and home building compensation (HBCF) cover is currently required for most residential building work above a set contract value — around $20,000 at the time of writing — which gives buyers additional comfort. Your contractor and conveyancer will confirm the current details.
Option 2: Diagnose and document, sell with the report
If you can’t fund the repair, the next best thing is removing the uncertainty. Commission the inspection and engineer’s assessment, get one or two itemised repair quotes, and make the package available to serious buyers. Now the negotiation is about a known number — “the fix is quoted at $22,000” — rather than a feared one. Buyers’ discounts tend to shrink towards the real repair cost when the guesswork is taken out.
Option 3: Sell as-is with a price adjustment
Fastest and simplest, but understand the economics: uncertainty is expensive. A buyer facing unknown foundation issues typically prices in the worst realistic case plus a margin for the hassle — which is why as-is discounts commonly exceed what the repair would actually have cost. Some buyers’ lenders may also take a cautious view of properties with significant unrepaired structural issues, which can thin out your buyer pool further (lending policies vary — this is a question for buyers and their banks, but it affects your market). Even under this option, a documented diagnosis usually pays for itself.
Option 4: Sell to the renovator and investor market
For houses with serious structural problems on good land — established streets in Turvey Park or Central Wagga, big blocks near the lake — the property may be worth marketing on its bones and location. These buyers price foundation work into their project budget as a matter of course and are less spooked by it. Expect land-value-anchored offers, and be upfront: this market respects a straight story.
A worked example (hypothetical, indicative only)
Say you own a three-bedroom brick veneer in Kooringal that might fetch around $560,000 in sound condition. It has stepped cracking along one wall, and an engineer’s assessment recommends five underpins plus crack making-good — quoted, say, at $26,000 all up (an indicative figure only).
- Fix first: spend ~$26,000, sell into the full buyer pool with documentation. Net position: around $534,000 before selling costs, with a faster, cleaner campaign.
- Document and sell: spend perhaps $1,500–$3,000 on the inspection, report and quotes. Buyers negotiate around the known $26,000 fix — perhaps settling $30,000–$40,000 below the sound-condition price.
- Sell as-is, undiagnosed: buyers see stepped cracks and no answers. Offers commonly come in $50,000–$80,000 under, or buyers walk after their building inspection and the campaign resets.
Every property and market is different, and these numbers are illustrative, not predictions. But the pattern is consistent: information is cheaper than uncertainty, whoever ends up paying for the repair.
What about disclosure? The NSW position, in plain terms
This is general information, not legal advice — your conveyancer or solicitor is the right person to advise on your sale.
- In NSW, the vendor disclosure regime centres on prescribed documents and warranties that must be attached to the contract of sale (planning certificate, title documents, drainage diagrams and so on) under the Conveyancing Act and its regulations. It doesn’t generally take the form of a checklist of physical defects.
- That said, you and your agent must not mislead buyers. Actively concealing a known structural problem — cosmetic patching timed for the campaign, untrue answers to direct questions — can expose you to real legal risk under consumer protection and contract law. Agents have their own obligations about material facts.
- In practice, the disclosure question often answers itself: most serious buyers commission a pre-purchase building inspection, and foundation movement is precisely what those inspections are designed to find. Assume it will be found, and plan accordingly.
The safe, sensible course: know the facts yourself, be accurate in what you and your agent say, hand over your documentation to serious buyers, and let your conveyancer handle the contract side. Rules and their interpretation change — check with your legal adviser rather than relying on any general guide, including this one.
Pre-listing checklist for a house with foundation concerns
- Book a foundation inspection, with engineer involvement if the inspector recommends it.
- Get at least one itemised repair quote from a licensed contractor.
- Decide your option — fix, document, discount or renovator market — using real numbers.
- If repairing: keep every document (engineer’s design, contract, licence details, HBCF certificate where applicable, completion paperwork).
- If not repairing: assemble the diagnosis package for serious buyers instead.
- Brief your agent honestly so nothing said in the campaign misleads anyone.
- Ask your conveyancer or solicitor to review how the issue should be handled in the contract.
Frequently asked questions
Do I legally have to tell buyers about foundation problems in NSW?
NSW’s mandatory disclosure rules are mostly about prescribed contract documents rather than a general list of defects — but you and your agent must not mislead buyers, and deliberately concealing a known structural problem is risky. Get specific advice from your conveyancer or solicitor for your situation.
Does underpinning devalue a house?
A documented, engineer-designed repair generally reads as a solved problem. What genuinely hurts value is unexplained cracking, undocumented patch-ups, or a repair with no paperwork. If your home was underpinned properly — whenever that happened — gather the records before you list.
Will buyers’ banks lend on a house with foundation issues?
Often yes for minor, documented issues; lenders can be more cautious where a valuation flags significant unrepaired structural problems. Policies vary between lenders and cases — it’s the buyer’s issue to resolve, but it shapes how many buyers can actually complete, which is worth factoring into your pricing.
Should I just fill and paint the cracks before the open home?
Repair honestly or leave them visible — don’t conceal. Fresh paint over stepped cracking is exactly what building inspectors look for, and a discovered cover-up poisons the negotiation worse than the cracks themselves. Proper crack repair after the cause is addressed is a different thing entirely, and worth doing.
Can I sell a house with foundation issues at auction?
Yes. Auctions can suit as-is sales because bidders compete on their own assessments — but serious bidders will want the building inspection done before auction day, so having your documentation ready matters even more, not less.
Is it worth fixing minor cracks before selling?
Usually, yes — once you know they’re minor. Stable cosmetic cracks professionally repaired and documented remove a cheap objection. The order matters: diagnose first, then repair once.
Work out your numbers before you list
The decision comes down to three figures: what the house is worth fixed, what the fix costs, and what buyers would knock off as-is. We can help you pin down the middle one — a proper inspection and an itemised repair quote from a licensed local specialist, with engineer involvement where required, and no pressure to proceed.
