You are in a strong affordability position compared to the UK average
Your income and disposable income are both above typical levels for UK buyers, giving you solid flexibility on housing, rent, and car choices.
Safe monthly disposable income
After expenses and debt, you have around £6,600 left each month — with a 10% safety buffer built in.
Home you could realistically afford
You could realistically afford a home worth around £488k based on your salary, savings, and financial position.
Most UK buyers with a similar income typically purchase between £429k and £546k
Recommended rent budget
A monthly rent of up to £2,917 would keep your finances healthy, based on the 30–35% income rule.
Car budget
You could comfortably afford a car between £10.0k and £15.0k. Staying closer to the lower figure keeps more budget for savings.

What the numbers mean for you
Standard lending multiple: Most UK mortgage lenders will lend between 4 and 4.5 times your annual salary. On a salary of £100k, that translates to a maximum mortgage of roughly £400k to £450k.
The £800k property: This home is 8.0 times your annual salary. This exceeds the standard lending multiple. You will need either a significant deposit or to explore specialist lending options.
Deposit strategy: A deposit of 25–40% is typically required for properties at this price-to-income ratio.
Which lenders to approach: Private banks and high-net-worth mortgage specialists are likely your best route at this borrowing level.
Other factors that affect lending: Credit score, employment type, existing debts, number of dependants, and monthly expenditure all influence what you can borrow. Speaking to an independent mortgage broker gives you the clearest picture of your real options.
