Can I afford a £300k house on a £45k salary in the UK?
Affording a £300k home on a £45k salary may be challenging but is not out of the question. With a salary multiple of around 6.7, you will likely need a deposit of at least 15–20% and a clean credit history to secure a mortgage from most high-street lenders.
This is significantly above standard lending criteria. Consider a lower price or increasing your salary.

Results update as you type
Your affordability is broadly in line with the UK average
You are well-positioned to afford a home, rent, or car within the typical UK range. Small improvements to expenses or savings will open up more options.
Safe monthly disposable income
After expenses and debt, you have around £2,475 left each month — with a 10% safety buffer built in.
Home you could realistically afford
You could realistically afford a home worth around £240k based on your salary, savings, and financial position.
Most UK buyers with a similar income typically purchase between £211k and £269k
Recommended rent budget
A monthly rent of up to £1,313 would keep your finances healthy, based on the 30–35% income rule.
Car budget
You could comfortably afford a car between £4.5k and £6.8k. 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 £45.0k, that translates to a maximum mortgage of roughly £180k to £203k.
The £300k property: This home is 6.7 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: You will likely need a deposit of 20–25% or more to meet lender requirements.
Which lenders to approach: Specialist lenders or a dedicated mortgage broker will be important in finding a suitable deal.
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.
