Husband 39 and I 39 are we are expecting our third baby later this summer. Our eldest is 3 and our second has just turned 1 so it is going to be busy but we are really excited to meet our baby.

We have recently announced to our families about the pregnancy and everyone seems happy for us. However my in laws have immediately started again about our housing situation.

For context, we bought a house 9 years ago. It was a 3 bed in SW London. We sold it in 2022 when we decided we wanted to start a family and change our priorities a bit. Since then we have been renting. I know renting is not ideal or particularly secure but it has worked for us for the time being while we figured out what we wanted long term.

We do have savings and we already have around a 30 percent deposit for an average 5 bed in SW or SE London. We have been actively looking and keeping an eye on the market. We would ideally like to stay in SW London but we have also seen some lovely houses in Dulwich so we are open to SE London as well.

The difficulty is that we are going to be a family of five so realistically we need a 5 or possibly even 6 bedroom house. As you can imagine those are not cheap in London. We have also considered moving further out into Surrey but we both work in London and need to be in the office twice a week so we cannot go too far out.

My in laws keep saying we need more stability for the children and they have now offered to help financially. Their suggestion is that they would contribute a large amount towards the deposit, roughly 50 percent. Between that and our savings we would obviously be able to buy somewhere much sooner and with far less pressure.

On paper it sounds incredibly generous and I do realise many people would jump at the offer. But I cannot help feeling uncomfortable about it. I worry that we would end up feeling like we owe them something or that it might blur boundaries later on or if there’s a breakdown of our marriage. We’ve been together since we were 19 at university.

My husband thinks I am massively overthinking and says they are just trying to help us and want their grandchildren to have a secure home. He says we would be silly to turn it down given how expensive London is. I think we are capable of buying our own place ourselves we’ve saved up enough for 30% deposit could probably add another 5% each to that. I don’t want his parents to later on say to us you have the house because of us or you have this because of us etc. They’re lovely in laws and I’m grateful but I also think boundaries are important once we start blurring it would mean they would get a say in a lot of aspects of my children’s lives which isn’t what I’m comfortable with.

DH and I have spoke and he’s said it’s my call he understands where I’m coming from. I feel bad saying no as it is a privilege but I just don’t want to feel as though I owe them something in return. Maybe I’m over thinking it and I’ve watched too many exaggerated tv dramas.

OP, what is confusing me, and other posters is not that you would like more rooms (wouldn’t we all!) but that you are holding out for something you can’t afford, as you said that you only have 30% of the deposit.

Edited

I think you’ve misunderstood it’s my fault really I wrote it in an odd way.

We have 30% deposit for a roughy 1.5m house.

You’re talking about a six bedroom house in Dulwich that would cost you about £2 million minimum. Consider 3 miles south of the where you get the same house for 50% less and not have this weird link with PIL.

We’ve viewed about 5 in Dulwich for 900 - 1.5 so far

ArtAngel · 16/03/2026 09:15

Indeed.

But in London it’s far less common. Due to astronomical house prices

Snd they are 39 years old and only have 30% of a deposit, so seem not to be able to afford 5 or 6 bedrooms

Outskirts of E Dulwich , 2 of the bedrooms are box rooms https://www.rightmove.co.uk/properties/173244881#/?channel=RES_BUY

We have a 30% deposit for a house worth around 1.5m. There’s been a bit of confusion with the wording.

Can’t see your maths on needing a 5/6 bedroom house. You’re a family of 5 so at the very most you NEED a 4 bed house. You WANT a 5/6 bedroom house.

Personally I think the gifted lump sum doesn’t work as much for you tied up in the house. I’d prefer a 70% LTV (since that’s usually the point at which interest is capped and further cash into the house doesn’t improve the mortgage deal) and invest the gifted lump sum elsewhere. A house in SE or SW London isn’t going to get you the best return.

However I assume it’s being gifted for mortgage purposes only, in which case it is what it is.

Not sure why your in-laws are getting involved in your finance and house purchase so much.

How long a mortgage term are you going for? A £1m+ mortgage at you both being 40 is an enormous reach.

5128gap · 16/03/2026 09:44

If your in laws are going to give you a very large sum of money, they would be extremely unusual to not think it bought them some degree of influence over your lives. Time and again people take these 'gifts' and are then surprised when the giver feels they deserve certain considerations or control in return.
The fact your in laws feel comfortable with telling you what they think is best for your family and being prepared to pay for things to be the way they think they should be, suggests this is precisely what will happen.
I think you need to weigh up how you will cope with their ongoing involvement and guidance. Is your H strong enough to tell them to MTOB if need be? Or will his gratitude put you under their thumbs?

We have given our children (both married) a lot of money to go towards moving up the housing ladder. I'd rather they had it now than wait till we are dead and they have to pay 40% IHT on it. As far as I know their partners are ok with it. I guess if they weren't they'd give it back.

Its a gift from us to them. How they spend it once it's theirs is down to them. They might well make choices we wouldn't but once it's their money what they do with it is none of our business. I trust them - they've mostly made good choices in life so far.

But you helped all of your children, not just your favourite child, even though the others were also in need. That's the difference.

Papyrophile · 16/03/2026 09:48

HNRTFT but Take the money. Consider it tax planning. Otherwise a large chuck could go in inheritance tax. We are giving our DC a large chunk while it is statistically likely that we have seven years to live.

Proud because I’m against repulsive behaviour at the expense of DHs siblings
fair enough then I’d rather be that.

I'm on the same page as you OP. I couldn't accept this kind of sum when your DHs siblings are getting no help.

I really think you owe it to yourself to challenge them on that. You can't really sit there and have an opinion of unfairness without challenging those at the root of it.

P.s What's with all the strange people who seem aghast about a spare room?!

We sold a house for 35% higher than it's worth now. That pays a lot of months of rent whilst you ponder

Maybe your in-laws are worried about the seemingly bizarre decision to sell a 3 bed in SW London to start renting and want to make sure you're all safe and secure.

Imagine complaining about being offered a 50% deposit on a 5-6 bed house in Dulwich or SW London! Christ.

I'm sure you can get solicitors involved to draw up an agreement, or like someone else said repay it like a loan.

I am actually really shocked and I will accept the blame it’s my fault I may have sounded a bit entitled in the original post which is why everyone seems to be obsessed with telling me I don’t need a 5/6 bed. I think the word need triggered people and came out as out of touch. For that I am genuinely sorry.

Quite. Likewise, this is not about what the in-laws want. Anyone is quite within their rights to offer something to someone - what would be overstepping is to try to insist they accept it. And if DH's parents already have rather strident opinions as to what's best for OP's family - amply demonstrated by their concern for their housing situation the moment they find out OP is pregnant - then what on earth will they be like when they have bought further influence?

As far as OP's being 'proud' is concerned, this is the reverse of being a bad thing. It shows both principle and independence.

It seems, however, that the decision is taken and IMO it's exactly the right one. It removes OP/DH from the obligation these gifts inevitably impose, and it safeguards DH's important relationships with his siblings. Plus both partners are on the same page, which is important.

Sounds to me like a good resolution all round.

20 years, they’re saying we are low risk and haven’t said our age is an issue but if you’re mortgage advisor or financial advisor or you work in real estate I’d love to hear another perspective from another professional. Always open to advice.

We have thought about this, it’s not just a light decision that we are making. I think there seems to be the assumption that DH and I have not sat down and looked at our finances and just decided to go to house viewing w/o a plan. We did put in an offer on a place and it was accepted but we pulled out after the survey. We do know a little bit about what we are doing we aren’t experts but we have done our research which is why I’m also less inclined to take money off on DHs parents at the expense of his siblings.

I’m on the opposite end of this.

i have given both my children a substantial amount of money towards a house. I do not want it back at any point and I’d rather they got the money now than after I am dead.

Exactly this! We have given sizeable deposit for DDs house. Everything we give to her and the DGC is of much greater benefit to her and her family now, rather than waiting until we die.

How does our SIL feel about it? Not to sure! He benefits. They both work, provide for their family and so anything that we contribute benefits the whole family.

Life is hard for young families right now. You OP,
have a good job, manage finances well and have financial security. The PILs contributing to this is the rational of the extended family, where we all play a part in the fortunes of the next generation rather than that of the nuclear family, which aims for self sufficiency and independence. Neither is wrong.

OP, you know whether your PIL are the type of people that would have expectations or whether this offer has the potential to blur boundaries. If it is offered/given with purely altruistic intent accept and live happily ever after. If not politely decline.

Do I not have a right to say no ? What’s so bad about saying no

There’s a dynamic here that I just don’t want to be involved in. My children can benefit from the money if they’d like to they can sort that out now for the children more than happy for that but I’m not living in a house bought by my in laws who can watch their other children struggle and not even offer to help.

OP posts:
Esperanza25 · 16/03/2026 10:09

I wouldn’t accept it unless your PIL were going to even things up with their other children by giving them some money too. Your husband’s siblings will most likely be around a lot longer than your PIL and I’d want to maintain good relationships with them.
I have seen first hand what can happen when one sibling is favoured and given financial help while the other is not. In the cases I’m thinking of, there were long lasting negative effects. It’s not worth it.
I also don’t understand the focus on bedrooms! If you can afford it, of course your children should have a room each and it’s always handy to have a spare.

Where did I say you hadn't sat down and thought about it? I simply asked the mortgage term, because borrowing £1m+ at 40 years old IS a huge reach, no matter how you look at it. Unfortunately at 40+ you're entering the biggest risk age bracket for redundancy, health problems and also the highest years of life costs. It's perfectly sensible to ask what mortgage term you're aiming for.

they’re saying we are low risk and haven’t said our age is an issue

Who's 'they'? The lender?

I think at 40 years old it's too high a mortgage to sustain now entering the latter years of your life, yes. And that's coming from someone who also has a large mortgage and high income, not a place of frugality. So yes, if your in-laws concern of 'stability' is for those reasons, then I see your point.

LancashireButterPie · 16/03/2026 10:24

No way would I accept this gift if they have no plans to offer similar sums to your DHs siblings.

Buy a cheaper home on your own two feet.

Hoolieghoul · 16/03/2026 10:26

Whether or not you accept the money is up to you and your personal feelings. However I can't get over the fact that you've decided to throw away money on rent for NINE YEARS instead of building equity for you and your children's futures because you've decided a five or six bedroom house is a necessity for two adults and three children?

Genuinely, read that aloud to yourself and tell us what the logic was there.

I think you should accept the money on the basis of Christ knows what other mad decisions you'll make if left to your own devices.
