Would you buy a house with historic subsidence?

22 replies

Tintinuviel · 14/02/2026 19:08

We've recently made an offer just under 420k on a ready to live in 3 bed house that we really liked. This seems to be around what a property like that goes for in the area; some sell for as little as 400k, others seem to be on the market for 450k.

However some issues have come up since we offered, and we want to know how to respond reasonably.

The house has previously been treated for subsidence by the current owners - I think around 2021, and observed between 2021 and 2024 with no further concerns, and given a certificate of adequacy in 2025. However the underwriting company who provided it have only given a guarantee for 24 months. Would indemnity insurance be helpful here?

The subsidence was due to trees a couple of houses down the road, that now have a plan for regular trimming. However, as they have not been cut down, it may potentially recur in future.

The work on the home we hope to buy was only crack filling and redecoration, and this was actually not picked up on the survey! We got a structural engineer review that did not bring up any new concerns. The neighbors had it worse; there was some form of more intensive treatment on the 2 or 3 closest neighbors' homes on that side.

Our potential mortgage provider has said that they will be happy to give us a mortgage and their valuation remains unaffected as long as insurance is available on "standard terms". We aren't sure exactly what this means - we've found an insurer willing to provide insurance (that whilst pricey is similar to what we got before we knew about the subsidence). It sounds like they do cover houses with historic subsidence, including for future subsidence but there's a £1000 excess. Which seems reasonable, However they may be a specialist insurer - would this void the terms of the mortgage? Should we ask the mortgage provider to vet the terms of our insurance policy?

I've seen people suggest before that we can ask the seller's insurance company to transfer the policy to us or to take us on - has anyone here done that before?

To add do that, we've found out the central heating isn't working in the property. This wasn't mentioned in the advert or during viewings before we offered. Should we get them to hire someone to take a look at it before we go any further and hive us an estimateof how much it would take to fix? What is reasonable to ask?

The roof apparently needs some work, the mortar under the ridge tiles is cracked and some times may slip, so immediate repair was recommended, as well as other more major fixes that could be put off, like replacing the sarking. Whilst annoying, this seems par for the course for an older property (like possoblr asbestos), but some of the isssues are flagged as immediate - should this be added to any reduction we ask for?

In total it could take us up to 17k over a few years. But the engineer wasn't really concerned about the roof and suggested it would be fine to address this down the road.

Another issue is that the garden backs onto green land, and there is a plan for some work to be done on that land which would pernanently affect the view and noise level from the garden unfortunately. It won't be residential property and there's no guarantee that the work will go ahead, but this is still a deviation from what we expected that wasn't declared at the time.

With this in mind, we're having to really consider if this is still what we want. We do genuinely like the home a lot, and it may be a while before we find another property we like in the area. We need to upsize fairly soon due to starting a family and we worry that similar properties in the area are hitting the market for around 450k or more abd it could be a long time before we find something we like...which could also have similar issues.

I know a lot of advice may be to back out due to the subsidence. And that is good advice.

But I'd also love to hear... if we do go forward with the purchase, should we lower our offer to reflect these issues given they weren't known when we offered? How much would you suggest potentially reducing an offer? What could we do to minimise the risks if we did take it on? Any advice appreciated.

I've posted this on other property forums in the hope of getting an idea of whether we can minimise the risks or whether we should bail.

The work on the green land behind would put me off moving this forward.

I also personally wouldn’t buy something that has had subsidence issues.

I like your measured and realistic approach, however I think you have a number of niggles with this property now and it may be best to walk away. Something better is out there waiting for you!

Neveranynamesleft · 14/02/2026 19:21

No. Look elsewhere.

EmmasDilemmas · 14/02/2026 19:21

I would consider a house with any one of the issues you have mentioned (subject to getting insurance etc) but with all of them, I’d walk away. Too many risks in too many areas that the house will cost you more than you expect / be hard to sell later.

dijonketchup · 14/02/2026 19:27

You mention you may be looking to move again before too long.

I think the biggest issue for me would not be the insurance etc, as it sounds like you can personally live with the risk. It’s that when selling this house you will have to declare all this to a prospective buyer, who will be similarly put off and may pull out.

It’s one thing accepting compromises because you love the house, but remember you have to find someone equally willing to do so when you sell it.

MrTibbles · 14/02/2026 20:03

The subsidence issue and the planning next to the back garden are big deals.

The roof and central heating are comparatively small (although the heating will need fixing).

They definitely affect market value of property. With the subsidence speak to an insurance broker for future coverage - not a comparison website.

Yeah this is it. I don't think we want to walk away reflexively, so for us doing out due dilligence abd asking around before deciding seemed fair.

I was sad about the work behind the garden tbh because the view now is lovely! I feel like it was a definite selling point that now is potentially ending, oit of our control.

Yeah when there are a few different issues it's hard to know how much is TOO much, y'know? My husband abd i have been talking about it a lot.

It's also sad that all this has kind of taken the shine off it, and it makes me wonder if, even if we did renegotiate a lower price that felt fair, whether we'd regret buying even if nothing went wrong. We really like it but I feel kind of bittersweet about it. Tbh being 8 months pregnant is NOT helping!

Yeah this has been our gut worry - at what point will the money we have to sink in or lose mean it would have just been cheaper and safer to buy another home?

Our surveyor and engineer thought it a nice property, too. It's a real head versus heart situation.

We spoke to a broker on the phone. Looks like if IS incurable but with more limited options, tough to know if we are comfortable that.

Yeah this is it.

We don't plan to move until our pending child (due soon, adding to the drama) goes to secondary school - if needed (as primaries nearby are good and there's at least one decent secondary in the area). So we could potentially easily stay for a decade or more.

But you never know if other circumstances might make you want to move sooner. And in those instances it looks like it might be really hard.

But the idea of being stuck with our baby in our 1 bed indefinitely is also not appealing!

We did. Could get insurance on standard terms and it is so hard to buy in this area so I think we’d easily resell if we wanted to. Which we don’t! This is a long term home.

Travelfairy · 15/02/2026 15:41

No

kirinm · 15/02/2026 15:42

Our entire area is high risk for subsidence so it’s a risk for every house in the area. Still a hugely popular area.

CurlyKoalie · 15/02/2026 17:05

It's a lot of money to pay for a house with this many faults already visible before you even you start buying things to put your own stamp on it.
The old subsidence and the fact that something unknown is going to appear at the back of the garden would be very worrying for me.
Unless you have pots of money and don't care about the neighbours behind you, I wouldn't be thinking of this as a long term forever home.

Gonnagetgoingreturnsagain · 15/02/2026 17:07

I’d pull out. Too many issues.

catipuss · 15/02/2026 17:12

If the cause of the subsidence hasn't been permanently fixed, I wouldn't buy. Who controls the work to keep the problem tree in check? Too risky for me.

mikado1 · 15/02/2026 17:38

I spoke to a builder about cracks in our walls - again the surveyor hadn't picked up or even mentioned. Builder said very lightly, yes probably structural maybe subsidence, every house has cracks, I wouldn't worry about it, not going to fall down!! So got an engineer to check and he's also fine with it.. so we've filled in the cracks and that's it.. but it does make me nervous and am mad the stupid overpriced surveyor didn't say a word. I'd pull out if I was you.

Yeah this is it. I'm looking somewhere where subsidence is very common, and likely to become much more so in the next 5-20 years. I wonder if it's as much of an issue selling in an area where it is common.

Oh we know what's appearing behind the garden, I was being vague for online purposes as i wasnt sure how much detail is relevant. The green area is owned by a school. So it's not going to be an unknown factor and won't be multi storey.

Yeah our fear is what else may come up and whether the subsidence will prove more costly in the long run than anticipated. And whether other issues will come out of the woodwork...like the fact the central heating doesn't work.

We do have some funds, bevause we got am offer accepted for quite a bit lower than we can afford. But I don't kniw whether it's safer to go fir this.. or a more expensive property with less issues.

Currently the council. Who i guess are less unreliable than random neighbors. But also a lot less control than if the trees were ours.

Thank you. It's been very useful hearing a range of opinions, bevause we're quite cautious and don't kniw if we're being TOO cautious if that makes sense.

One word: no. Life is stressful enough, you are just asking for problems and spending lots of money.
