Money and house issues on breaking up

[moneymoneymoneyohdear]

DP and I are incredibly likely to break up, as sad as that is.
We own a house together but have no DC's
I can afford to buy DP out of the house luckily

Can anyone tell me whether I will have to pay stamp duty on paying his share of the property?

Also our house has not increased in value compared to the money gone in. If anything its reduced in value. Would I be unreasonable to give him the money he has put in but nothing more?

We've owned together under a year if that makes any difference.

As you aren't married then stamp duty is payable.

I think it depends on the amount you will pay to buy him out, if it's below the stamp duty threshold then you won't pay it.
Have a look here on the gov.uk website, sorry can't link!

Ah that's great, thanks. I think it will be below the threshold, phew

He may also need to consider that he may have to pay capital gains tax if he doesn't put it into another property for himself.

There won't be capital gains tax if he's lived there during the time the gains were made (very simplified but the exemption I think will be most applicable).

He's only paid into the mortgage so it's a very small amount of money to pay him what he's paid in
