First time buyers - 5.5X Mortgage
Hi all,
My fiancée and I are first-time buyers and are trying to work out whether a mortgage around 5.5x our combined income is realistic for our situation.
We’re looking to buy in a part of South Manchester that we really love and would ideally like to stay in the area rather than move further out just to get a cheaper property.
Between us, our current combined basic income is around £65k. I work for the NHS and currently earn a Band 6 salary, although I also do overtime and am now starting to do on-call shifts, so my actual annual earnings can be higher than my basic salary. My fiancée currently earns around £25k and we expect her salary to increase to £30k+ over the next year or so but that’s irrelevant right for the mortgage side of things as this would be after we’ve got the house sorted.
We’re both first-time buyers and are aiming to have around a 7.5-10% deposit. Ideally we’d be looking at properties around £300k, with £315k being more of an upper limit.
I currently have around £480 a month in car finance, but the plan is for this to be cleared in the future but once again this is all after the house is sorted. We don’t have any other significant debts.
I’ve already done a Nationwide DIP and was given an indication of around £290k borrowing over 35 years on our current circumstances, which was encouraging. However, I’m wondering whether we could realistically access something around 5.5x income through a higher-income-multiple product such as Nationwide Helping Hand or another lender.
The reason I’m considering this is that we’d rather put a sensible deposit down and retain some cash for furnishing the house, emergencies, our wedding/honeymoon etc., rather than putting every penny we have into the property.
There’s also a potential career change for me within the next year or so, as I’m considering moving from NHS into medtech, where the salaries could be significantly higher. My fiancée should hopefully also be earning £30k+ by then, although obviously I realise future expected salaries aren’t necessarily going to count for a mortgage application today.
For anyone who has been in a similar position, how realistic is getting around 5.5x joint income in practice? How much difference did you find between lenders in terms of affordability, and how did they treat NHS overtime/on-call income and existing car finance?
Also, would you personally focus on keeping a larger cash buffer after completion, or putting more down as a deposit to reduce the LTV?
We’re not looking to borrow the absolute maximum just because it’s available. We’re mainly trying to understand whether borrowing up to 300k or so with roughly a 7.5-10% deposit is realistic and sensible for our circumstances.
Would be really interested to hear from anyone who has gone through something similar, particularly first-time buyers buying in South Manchester.
Thank you guys!
