How old are you?
If home ownership is important to you, as opposed to staying in rented, you just need to bite the bullet and go for it. There are too many variables to be able to control every aspect of it. You can’t time the market. You need to just make the jump.
I am kind of of the opinion stretch yourself for the best house you can get - and by that I mean size / best area / potential. Not one that’s been done up and dressed nicely. But would caveat that with not stretching yourself to a silly degree. Find the balance.
Rememeber that the value of the purchase price is only going to go down in real terms.
The sooner you get the mortgage loan and start paying g it off, the sooner the debt will go down.
Have contingencies for if rates go massively up or if you lose your job etc. so for example I have insurance in case of ill health and I have redundancy insurance (I work in a volatile sector). But if I am unemployed for any other reason, I would stop paying for the kids wraparound care (which is extortionate), would stop our cleaner, and would sell our car as it wouldn’t be needed (currently need it for work). Husband would also easily be able to take on more shifts as I’d be around to do all childcare.
Likewise, if mortgage rates go up exponentially, I can take on extra shifts at work.
The mortgage is also due to end at my age 60, so I could extend that probably by around 7 years to bring payments down.
I think it’s a state of mind thing. I understand some people don’t like uncertainty but it’s really the only way.
