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.

Why 5 or 6 bedrooms?

Will this be a gift or loan? How old are in-laws? Would this impact them financially? Any siblings who would be aggrieved?

If they can afford it and it's a gift, not a loan then take it. I plan to gift my children money and can't see why they wouldn't take it.

You are overthinking. And why would you need such a large house? 4 bed would be fine, a room each for the kids plus yours.

That way you won’t need such a large deposit anyway

Take the money. As others have said it only comes to you and your husband when they pass anyway and if they are in a position to do it now, take it.

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.

Take it, before the tax man does

You are massively overthinking it. The money is heading your way at some point anyway.
You are the mother of those three children if you take the money now whilst you’re married you benefit from it
If at any point in the future your relationship were to fail
Your DH benefits from it you don’t and you still got to house those three children.
