This data is taken from the Nationwide House Price index and represents the average price of a house.
With a mortgage of £423,830.00 at 4.75% you are looking at repayments of £2416.33 per calendar month for 25 years1.
This is 71.07% of the net monthly income in your household.
After each payment, you will be left with £983.67 for other expenditure.
Most lenders will only lend up to 4.5x the gross income of your household2. This means to qualify for the mortgage, you will need to have a gross annual income of at least £94,184.44
With stricter lending rules that came into force 26th April 2014, lenders may also take into account your discretionary expenditure when deciding your eligibility for a mortgage3.
1 This is assuming the interest rate on your mortgage stays fixed.
2 Some lenders might only consider 4x or even 3x your gross annual income. Check with your lender to find out what their policy is.

With mortgage repayments taking up 71.07% of your monthly income, you will be left with £983.67 to cover other life expenditure.
You need to seriously consider whether you will be able to keep up with the repayments. Especially when the interest rate on your mortgage is variable, any hike in rates could leave you in a financially difficult position (check out the things to consider panel to see how this might affect you.)
Even just a 1% raise would increase your monthly repayments to £2666.34 (78.42%.)
Remember that you will need money for: -
As well as taking into consideration: -
It's difficult to gauge what an appropriate percentage of your take home pay should be dedicated to servicing debts, as there isn't really that much of an official figure.
However the general consensous appears to suggest that 36% or below is the most advisable1.
This is how the ratings are determined2
|Rating||% of income|
|Affordable||36% or below|
|Acceptable||40% or below|
|Expensive||52% or below|
|Dangerous||greater than 52%|
2 These ratings are not to be taken as financial advice, they should just be used as a guide.
Buying a house is expensive.
