If you are sure you hate the house, OP, get out sooner rather than later.
My sad (long) story from nearly 10 years ago:
We were moving cities for work, so needed to find somewhere to buy.
Husband spotted this house on Rightmove and showed me, said he liked it.
I didn't like it, just from the Rightmove listing alone.
Husband travelled up by himself to do the first viewing (I was busy), came back talking about how great it was, lots of potential, blah blah.
Eventually we both went to view it again together. My initial dislike became a strong dislike upon viewing. I spotted various problems that DH with his rose-tinted glasses hadn't, but he insisted that I was just being nitpicky, biased, fussy, etc.
To husband's displeasure I refused to offer on it, instead desperately trawled the market for literally anything else. But market conditions at that specific time were really weird, hardly anything on the market, and anything halfway decent got snapped up at wayyyyy over the asking price.
Eventually, as yet another house purchase fell through, husband begged me to reconsider his "dream" house and we put in a low offer. It wasn't a surprise to me when the offer was accepted, because I'd noticed the house had been on the market with various agents for over a year.
Survey highlighted more issues that I hadn't spotted on my single, disdainful, viewing. We discussed pulling out and renting. Husband persuaded me that we could just reduce our offer. Which, unsurprisingly, was also accepted (with a bit of give-and-take).
Husband said "Don't worry, we'll make this house a home."
The day we moved in, my strong dislike turned to utter loathing. And it quickly became obvious that the survey had missed yet more issues. By this time, husband had become completely fixated on "his" house and couldn't take any criticism of it from me, seeing it as a personal attack.
So - Living in the house caused me such severe mental health problems that I had to give up my career, and nearly destroyed my marriage. We've had to have marriage counselling. Money has been so tight - we have scraped together enough, every few years, to fix some of the things, but I don't even enjoy the bits of the house that we have done because all I can see is the towering stack of issues and all the sadness it has brought to my life. I resent every £ we've had to spend on the house and every bit of cleaning, repair, maintenance that I have to do on it - made worse because often husband is in denial about any possibility of issues or repairs being needed.
And it'll always be there in all my precious memories of my DCs growing up
