AIBU to feel uncomfortable about my in laws offering a huge house deposit?

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.

Following your update, I can see why you’re uncomfortable about this. I think his siblings will feel quite upset about it. Why haven’t his parents offered anything to them? Can they afford to do the same to all of them?

NotNow178 · 15/03/2026 14:52

I would refuse it.

itsgettingweird · 15/03/2026 14:53

Are you an over thinker in general?

Being gifted a house deposit or money towards it is one of the more normal states of play in everyday life.

Unless your ILs are likely to feel they have a right to choose the house or have a key then YABU

LayaM · 15/03/2026 14:57

We accepted a large contribution from my in laws and in return my MIL has expected a certain amount of say in the house, like when we got a new kitchen she wanted to be consulted for example. She's currently encouraging us to convert the loft. She's generally fairly opinionated about the children although it's more the house she's focused on.

I'd prefer if she'd butt out, but given we've got a much nicer house in a better area on her account, I kind of see that as the deal. If I put my foot down she does accept it so it's manageable if a bit irritating at times. It hasn't ruined our relationship or anything.

So I suppose my question would be, do you really think it's going to be such a big problem, why such strict boundaries? So what if the boundaries do get a little blurred? Can't you manage that accordingly given the huge favour they are doing you? I don't get why you think such firm boundaries are so important, they're your family?

OttilieKnackered · 15/03/2026 14:58

Absolutely howling at the idea you ‘realistically’ ‘need’ six bedrooms. You could even have three and shock horror have two kids share. They’ll all be close in age.

We’d all like a spare room or three but hardly a necessity.

I certainly wouldn’t be taking huge amounts of money with strings or family strife attached to enable such excessive housing.

No not usually an over thinker

I would like to take them up on their generous offer I really would but it just doesn’t sit right with me that none of my husbands siblings had this offer. His sister and her husband really struggled to get a family house, they have one now but PIL would have been able to assist but did not. I think there’s a favouritism aspect to this that I’m not too comfortable with.

Why do you need a 5 or 6 bedroom house for a family of 5? My daughter has three children and manages fine in a 4 bedroom house. In fact they feel they are privileged to be able to give each child their own room. No one needs 6 bedrooms.
I think you are wasting money renting when you can afford to buy somewhere suitable which you can easily do without help from your in laws.

Maybe not but I think my children deserve their own space regardless of how close in age they are so even if we don’t get 5 we will definitely get 4.

That’s just something that is non negotiable for us in our house search and it’s important for DH and I.

Absolutely if that’s what you want. There will be way more 4 bed options than 5 or 6 though.

There’s obviously plenty of money floating about to contemplate even a four bed house in SW London so personally I would just try and do it yourselves.

Octavia64 · 15/03/2026 14:04

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.

This! Much better to get money at a point it is needed and where the person giving can see the benefit for themselves. May also be tax efficient.

A bit more context

DH is the youngest of 4
PIL never offered to help any of the other children with deposits or anything. My sister in law and her husband were renting for a long time, PIL did not offer to help them. They have the money to.
DH knows he’s the favourite
DHs siblings might be upset they’re all the house ladder now but I think it would still hurt because their parents have always had money but never offered to help the others.

You could accept the money as a loan, (a gift would have tax implications) have a contract drawn up. PIL would effectively have a second mortgage on the house. So bank has first mortgage. If you sell due to a split or house change, bank gets their money, parents get theirs, then you & DH split the remainder. Neither bank nor PIL gain from increase in equity, nor have any say in anything you do with your house. The terms of the loan/2nd mortgage is agreed up front, it doesn’t have to have any repayment terms unless you choose that. Your PIL could also choose to reduce the mortgage/loan by a set amount each year (within current tax free gift amounts)
They can choose to either will the amount to you on their death, or have the amount put back in the entire inheritance pot so that siblings also benefit.

That way they get to help golden boy, but you and siblings would feel it’s fair.
completely refusing will insult PIL & annoy DH, so get the benefit whilst protecting everyone.

MerryUmberHedgehog · 15/03/2026 15:07

Im sorry but are you any good at maths? 1 bedroom each (lucky them. I had to share till I was 16 and my own kids had to share for a few years too). Plus 1 bedroom for you = 4.
Realistically 5 or 6 bedrooms? You sound a tad entitled to me without any understanding of the real world. Accept the loan or buy a smaller house. Who cares. Youre lucky thats all you have to worry about.

Canyonroadjack · 15/03/2026 15:10

I wouldn’t take it either. The potential to piss off the siblings is massive, as is the possibility that the PILs will move themselves in/think they have a say in every thing.

In that case it would be a hard no from me. Sibling relationships are too important to risk imo.

WhatAMarvelousTune · 15/03/2026 15:18

With the info about the siblings I can see why you’re hesitant. My parents gave my sibling £70k for a house deposit, and nothing to me and my other sibling. No reason, sibling is a high earner, could have afforded the house by themselves but my parents “wanted to bring down the mortgage”.

You describe your PIL as “lovely” but I don’t consider this to be something a lovely parent does.

Somewhat ironically I do actually have a maths degree. Only a 2:1 and I did find parts of it challenging so perhaps you are right, I’m terrible at maths.

The reason I mentioned wanting a spare bedroom is for a practical reason. My niece is hoping to come and live with us when she starts sixth form in 2027. She has a scholarship if she gets the grades for a private school near us and it would make things much easier for her if she could stay with us, we have a spare room currently in the house we are renting but hoping we move out and buy our place by end of this year.

my niece works incredibly hard and is a genuinely lovely girl. I enjoy spending time with her and would be very happy to support her if I can. My siblings and I did not grow up with many opportunities, so this feels like a really positive one for her. She is even hoping to apply to Oxbridge for undergrad, so if I can play a small part in helping I will.

I know we are very privileged trust me I was a free school meals kid & more. I didn’t mean for my comment on the rooms to come off like that but I do understand how privileged we are.

Entirely up to you if you want a large house. I can’t understand posters questioning why you’d want 5+ bedrooms, it’s your choice if you have this extra money, total red herring.

The real issue here is “DH is their favourite” this is just really toxic and I’d be running a mile from these people. Unless you know that his siblings will inherit more in their will and your DH is just getting his share upfront?

what is your DH’s relationship with his siblings like and is this likely to drive a further wedge? Is that worth the bigger house? I mean it might be, if he’s not especially close to them or doesn’t care.

FWIW my sister and I have had large gifts from our parents and it’s always been exactly equal. I cannot imagine my parents helping one of us and not the other and I’d never do this to my DC. What kind of parents must they be?

Why shouldn’t the OP aim for a bigger house if that’s what she wants for her family just because your DD “manages fine”? It’s not a race to the bottom, as MN loves to say.

Midlifecrisisaverted · 15/03/2026 15:34

I personally wouldn't be comfortable with this. Money does strange things to people and so many relationships get fractured because of it. I'd rather pay for my own stuff and not risk owing anybody anything, or risk any bad feelings now or in the future. You're gut is telling you something, probably wise to listen to it

They don't want to 'manage'. They want to have plenty of space. Why would anyone choose to live in cramped conditions if they didn't need to.

dairydebris · 15/03/2026 15:39

Odd that people are disparaging over wanting spare bedrooms... your kids will always want friends to stay and so will you... I'd love a guest bedroom and another spare / office.

I think you shouldn't take the money but rather find a way of doing it yourselves. You've got a few areas of flexibility, sounds like youre in a great position overall.

I think taking such a large amount of money that wasn't gifted to other siblings will be problematic in the future. And you can make it work without the extra cash.

feellikeanalien · 15/03/2026 15:40

How do you think your DH's siblings will react? Is it likely to damage their relationships?
