Is this fair?

If you’re going to go this far (and I don’t think it would be wrong to, necessarily) you also need to account for the appreciating asset of the house itself. Even though you might be out of pocket in the moment, a significant amount of the expenses are going into buying an asset you can sell at a later date, at which point you’ll be making a significant profit.

So he gets cheaper bills, his mortgage covered an £1k on top, you get cheaper bills. That's a really good deal I just have one change, you move into his place and rent out your place.

Suggest looking at a spreadsheet showing how you’d both fare and comparing it to you moving in with him, renting your own home out and only paying half the bills.

Exactly this. You should both see a financial benefit to the arrangement.

@Picklestop I think you are missing the point.

This isn't about a credit card bill.

It's about a new arrangement of him moving in which should benefit them BOTH, not just him.

If the tables were turned, I somehow doubt he would be happy for the OP to gain a rental income, and he gains nothing.

OP called it rent.

And sharing her capital mortgage payments is not sharing a living expense. That is like saying if she had massive credit card bills (a mortgage is just a debt) he should start to contribute to paying those off if he moved in.

The only expense item here is the mortgage interest cost and any general house maintenance, e.g. annual boiler service, which I have suggested is split.

DH moved into my house and I charged him half the morgage and half the bills - half the cost of living in my house, plus £100 a month on top so we could have holidays together:

I sold and we put my equity down as a deposit: it’s not ring fenced.

He saved as he wasn’t paying double for a shared house and have use of all the facilities.

Other than agent's fees, he had all of the other costs before or at least should have.

It's not rent, it's equally sharing the cost of living.

He's not a teenager and she's not his mother.

I cannot imagine charging a partner or spouse rent. But I think as well as bills he should make a contribution towards mortgage interest costs and general household maintenance.

Another thing to look at would be total outgoings for the two households separately, compare to the new combined expenses and share any saving.

You should equally benefit from moving in together both financially and with the housework/DIY/chores etc.

Why don't you suggest moving in to his or renting a place together?
3 different spreadsheets with all the costings.

If he doesn't want to engage with this you have your answer, he just wants to benefit from the arrangement and doesn't really want you to benefit.

I live alone and there are lots of positives, as well as negatives, don't lose all the positives and none of the negatives so he can be mortgage free as soon as possible!

No he isn't. He has tax, insurance, agents fees, maintenance costs etc, gas certification, electrical certification and other outgoings. Rent is never 100% profit despite what those who rent assume.

Yes potentially he could share profit element by way of rent.

OK well I think he's trying to gaslight you and live off you, so really I think you shouldn't be with this complete loser.

Other than that, if he was an amazing man in this position I'd say: rent out his place and he should pay the tax on that income. Then whatever's left should be split between you. With his 50% he can pay the mortgage and then with your 50% you can overpay your mortgage, or you could each do whatever you want with the money. Each of you is responsible for any jobs on your own places.

Once in your place, all bills should then be split 50:50.

But, as I say, he's seeing you as a quick way to pay off his mortgage, so I would tell him where to go.

@Hummusandstuff

"Bit of a worry if he thinks he should be the only one to benefit."

My thoughts exactly.

He can pay his mortgage off quickly by moving in with you and you should be able to do the same. And yes I would think a woman moving to someone else’s house should contribute.
He should pay around half your total bills. You’ll both benefit.
Bit of a worry if he thinks he should be the only one to benefit.

FWIW, I'd say the agreement needed to be clear before he moved in. It makes everything so much easier if it's all discussed and agreement hound before the move in. That also has the advantage of finding out a bit more about what he is like as part of that process.

Only raising it or evenjbgxstartingctovthijnjxabpugbifbknce moved in is really not the right way imo.

You both should be benefiting equally from co-habiting.

At present, he is up £1500 but you are up nothing.

He puts £750 towards his mortgage and pays you £750 rent.

I'm probably going to move into to my DPs soon, unless we find a new house to buy, and I'll be saving in rent, if I give my him what I had been paying, then we benefiting equally.

What would he say if you suggested renting a place together and both renting your respective homes out? Be interesting to see how keen he is once it isn't going to make him a packet.

When my partner moved in they paid half the bills and half the interest for the mortgage as "rent"

He wins and saves but I'm inconvenienced since giving up my space etc

WTF? Have you ever lived with someone before? It's not meant to be an inconvenience

And she gets her mortgage paid off faster with his contribution which only she benefits from the equity in. Yeah, sounds fair. I'm sure MNers would be advising a woman she should be paying towards her partner's mortgage and sharing her rental income too if she moved in with him.
