It’s unlikely that you’d be able to borrow significantly more than your current salary would cover - say you took the maximum mortgage you could get, and it worked out at £900 per month - even if in theory you could afford to spend another £400 a month on your mortgage because you live a very frugal lifestyle, your mortgage provider is unlikely to consider it a safe/good investment; you need to leave some wiggle room for interest rates to fluctuate etc.
My mortgage advisor said that you generally don’t want to allocate more than a third of your monthly salary towards your mortgage payment. You’ll need to consider whether to take out a fixed rate mortgage or a variable rate, and how many years you want the mortgage over. Taking the mortgage out over a longer period of time doesn’t mean you can borrow more but generally the monthly payments are lower - however you would end up paying more on interest in the long run. Personally I chose to take my mortgage over a longer period of time to make it more affordable, and in the next few years I hope to start making ‘overpayments’ so I’ll be able to pay it off sooner and avoid paying more interest than I have to; however I’m not tied to that so if there are months I can’t/don’t want to overpay, I only have to pay my lower standard mortgage amount - anything else is a bonus.
When calculating the amount you can borrow, really little things like monthly financial commitments can have a big impact. When you’re ready to get started, try and cut down on any regular payments - don’t take out a new car on finance, see if you can freeze or cancel any gym memberships etc because all those things cut down on what you can borrow.
I hope that is at least slightly helpful - if you have any specific questions, let me know and I’ll do my best to answer!
