How much rent to charge

[onlyfoolsanddonkeys]

In the future my DP might move in with me, my mortgage is currently £630 fixed for 7 years. We would split the utility bills and I'd pay house insurance, boiler insurance etc.and any related maintenance on the house plus my own bills. How much would you charge?
Anyone been in this situation on either side?

Very much depends on so many factors not listed. Is there a chance he will go on the mortgage or you'll get married in the future?

@Perfect28 he wouldn't go on the mortgage. I have owned the house since 2005 so have a fair bit of equity. Marriage isn't on the cards. What other factors do I need to consider?
For context I bought my ex out of the house in 2012 so I want to keep it in my name.

I think £300 a month plus 50 50 on utilities sounds about right. It wouldn't be good to charge more if he will not have any more rights than a lodger.

@DrySherry that's a good point as he would have no security/contract. I was thinking £300 or less like a nominal charge as I will be saving money by splitting the bills.

Many years ago, when I moved in with my other half, we took a different approach.
There was no mortgage on her place so we split all the bills 50/50 (incl buildings and contents insurance, council tax, utilities etc). Then we looked at how much I was "saving" by not having to pay the rent in the place I was currently renting. I then paid half of that to her , so we were both "better off" by the same amount, if that makes sense.
Might be useful to see what the numbers look like if you do it on that basis?

@NameChangedToAnswer that's interesting. His half of the rent currently is more than my mortgage so he will gain out of it more and be in a house rather than a flat. Did you see the house as yours?

Has he suggested what he think is fair?

@OddBoots we've not got to that stage yet, it's just me thinking ahead. I guess it's hard to shake that feeling of 'they are paying towards your mortgage'

Didn't really see it as being "mine" until a couple of years later when I bought 50% of it. Not that my other half ever did anything to suggest it wasn't as much my home as hers, just in my head it was always more hers than mine.

Unrelated to that I half remember something I've seen before where a partner can obtain an interest in a property if they contribute towards the mortgage when co-habiting, even if no formal agreement has been signed. Possibly something you should bear in mind.

@NameChangedToAnswer that's very much on my mind too. I was burnt before as my parents paid for the deposit but me and ex jointly owned the house (not married) and I had to buy him out the house 50% and lost the deposit as I didn't have a legal agreement in place. In my eyes it should have been minus deposit then 50/50 on profit but house deeds were 50/50 and that's a legal document. I will be drawing up a romantic/legal document to sign!

I'd go 200, as its further away from "half" the mortgage so if things go sour, he can't say "well my rent was half the mortgage"

He also then covers 50% of the bills, plus the costs of anything specific to him (his phone etc).

What is the market rate to rent the house? Half that and then apply a discount of say 15%

Market rate is £1800. That would be £765. I am glad I own and don't rent!

Daft suggestion given that the market rent could be double whatever the OP pays in mortgage!

But what he would pay if not living with her but 100% not 50% with a further 15% discount. So not daft at all. I guess economics isn't your strong point.

So what if he would pay 100% of the rent and bills if he lived separately- obviously he would.

But he shouldn't be paying half of the market rent on a home his girlfriend owns, that he would be kicked out of if she wanted, at a moments notice!

At least renting (at 100% cost) gives him legal protection.

It's got fuck all to do with "economics" so don't patronise me.
