Selling a house with dry rot

Selling in Scotland is different from selling in England in one way that matters enormously here: the survey happens before anyone offers, and you are the one who pays for it. By the time a buyer is interested, they have already read what a chartered surveyor thought of your timber.

That single fact drives every decision on this page. You do not get to hope nobody notices. You get to decide what the report says about it, which is a much better position than it feels like right now.

Yes, you can sell it

Properties with rot sell in Scotland every week. Some sell at a discount, some sell for the same money after the work is done, and a few sell to cash buyers who wanted a project. None of those outcomes requires hiding anything, and the one that produces the worst result is the one where the seller waits to be found out.

The real question is not whether it is sellable. It is which of two routes costs you less: fix it first, or price it in.

What you must declare

The property questionnaire is part of the home report, you complete it yourself, and you sign it. It asks direct questions about the condition of the property and about work carried out.

Answer them accurately. Misleading a buyer about a known defect is not a technicality: it can support a claim against you after the sale, and a buyer who discovers on the day of entry what you knew in March will have your signed questionnaire and your specialist report to point at. That is a far worse day than a price negotiation.

If you have had rot treated, say so, and have the paperwork ready. Treated and documented is a genuinely reassuring answer. Untreated and undisclosed is the one that ends up with solicitors.

Fix it first, or price it in?

There is a real arithmetic here and it usually comes out the same way, but not always.

Fixing it first tends to win when:

• The outbreak is contained, the cause is identified and the work is a known quantity.
• You have the cash, or the work is small enough to fund from the sale proceeds through your solicitor.
• The property is otherwise strong and would sell well without the note in the report.
• You can get it done and get a fresh report before you go to market.

The reason it wins is that buyers discount for uncertainty far more heavily than for cost. A buyer reading “dry rot, extent unknown, specialist report required” is not mentally subtracting the price of the job. They are subtracting the worst thing they can imagine, then adding a margin for the risk of being wrong, then usually deciding to look at something else instead. That gap between the real cost and the imagined cost is what you are paying for when you leave it.

Pricing it in tends to win when:

• The extent genuinely is not known and finding out means major opening up.
• The cause sits in common property and depends on other owners in the close agreeing to a repair.
• You need to sell quickly, or you cannot fund the work.
• The likely buyer is a developer or a cash buyer who will do the whole flat anyway.

In that case the useful move is not to guess at a discount. It is to get a specialist report yourself, put a real number on it, and market the property with that number available. You are still selling at a discount, but at a discount you chose and can defend, rather than one the buyer invented.

Getting your own report before you market

This is the most underused move in a Scottish sale.

You commission a dry rot survey before the home report is done, and you go to market holding a written document that says what the problem is, how far it goes, what the cause is and what it costs to put right. Three things follow.

1. You control the narrative. The buyer’s imagination is replaced with a figure.
2. You remove the buyer’s delay. Most price renegotiations in Scotland happen because the buyer needs a specialist report and the seller has not got one, so the whole thing stalls for two weeks and the buyer gets nervous. If it already exists, that fortnight disappears.
3. You find out whether it is even live. Rot that dried out when a leak was fixed years ago is dead, and dead fungus in sound timber needs nothing done to it. Sellers discount themselves thousands of pounds for outbreaks that stopped in 2011.

If the report comes back with a small number, you fix it and market without the problem. If it comes back with a large one, you have found out at the point where you still have choices.

The home report categories, and what they cost you

The single survey grades each element. Category 1 means no repair needed. Category 2 means repair or replacement is needed but not urgently. Category 3 means urgent repair or replacement is needed, and buyers, lenders and solicitors all treat it as a flag.

The move from 2 to 3 is where the money goes, and it is often driven by uncertainty rather than severity: a surveyor who cannot establish the extent has little choice but to go to 3 and ask for a specialist. Which is another argument for having had somebody look before the surveyor arrives.

You cannot instruct a surveyor to soften a category. You can make sure they are working from full information, which sometimes changes what they write, and always changes how a buyer reads it.

Rot in a tenement is often not only yours

If you own a flat, check where the water is coming from before you commit to fixing anything, because the answer may not be inside your title.

Under Scottish tenement law the roof, the gutters, the downpipes and the structural walls are generally common, shared between the owners in the stair. A failed shared downpipe soaking a gable is a common repair, and treating the rot inside your flat while the water continues is money spent twice.

For a seller this cuts both ways. It may mean you are not solely liable for the cause, which is worth establishing in writing. It also means a buyer’s solicitor will ask whether any common repairs have been proposed or agreed, and an honest answer of “the close has been discussing the rainwater goods” is much better received before an offer than after one.

What a buyer will ask you

Have the answers ready. These come up almost every time:

• When was it first noticed, and by whom?
• What has been done about it, and by which firm?
• Is there a guarantee, and can it be assigned to me?
• Where was the water coming from, and has that been fixed?
• Has anyone opened up to see how far it goes?
• Have the other owners in the close been involved?

An assignable guarantee is worth real money at this point, because it transfers the protection to the buyer instead of dying with your ownership. What ours covers is on our guarantee.

If it turns out to be woodworm rather than rot

Much less serious, and much cheaper to deal with. Most woodworm in Scottish properties is historic and needs nothing, and buyers who have read anything on the subject generally know that. A short specialist letter confirming the infestation is not active is often enough to close the subject entirely, and it costs a fraction of what buyers try to knock off for it.

The distinction between the two rots matters too, and buyers get it wrong constantly in your favour or against it. Wet rot or dry rot sets out the difference, and wet rot is both far more common and far cheaper than the thing people assume when they see the word rot.

The order to do this in

1. Find out what you have, before the home report is instructed. Everything else is a guess until then.
2. Fix the water first. Whatever you decide about the timber, an unresolved leak devalues the property and invalidates any treatment.
3. Decide: repair or price. Using a real figure from a real report, not an estimate from a forum.
4. Complete the property questionnaire honestly, with the paperwork to hand.
5. Keep every document. Reports, invoices, guarantees, photographs of the work in progress. This is the file that answers a buyer's solicitor in one email instead of three weeks.

If you want the report that starts this off, that is a dry rot survey. Tell us at the outset that you are selling, because a report written for a seller needs to be clear enough for a buyer’s solicitor to read without a translator.
