Can I afford an £800k house on a £100k salary in the UK?
An £800k property on £100k (8× salary) is where the private banking market becomes most relevant. High-street lenders will not touch this ratio, and even most specialist lenders cap at 6×. However, private banks and high-net-worth mortgage providers assess your full financial picture — investments, pension, assets — not just your salary multiple. If you have wealth beyond your salary, this becomes a different conversation.
This is significantly above standard lending criteria. Consider a lower price or increasing your salary.

Results update as you type
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% buffer built in for unexpected costs. This is comfortable for most people at this income level.
Home you could realistically afford
Around £488k is a realistic target based on your salary, savings, and outgoings. Outside London, this budget typically goes further.
Most UK buyers with a similar income typically purchase between £429k and £546k
Recommended rent budget
Up to £2,917/month keeps your finances healthy based on the 30–35% income rule. Anything above this may start to feel like a stretch.
Car finance calculator
Most cars in the UK are purchased using finance (PCP or HP), where buyers pay a deposit and a fixed monthly cost. This estimate gives a realistic guide based on typical finance rates (~8% APR).
How much you can comfortably pay each month
£200–£350/month is a sensible range for most UK buyers. This is what many people on a typical salary comfortably spend on a car.
Most UK car buyers use PCP or HP finance — affordability is based on monthly payments, not total price.
Outside London, this budget typically goes further. In London and higher-cost areas, affordability is usually 15–25% lower than these figures suggest.

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.

A realistic buyer scenario
Michael, 51 — technology director, North London
Michael earns £100,000 and has £220,000 in a Stocks & Shares ISA alongside £35,000 in cash savings. He is not planning to liquidate investments but wants to buy an £800,000 Victorian semi in Highgate, North London. He previously owned a property and has a strong credit record.
A private bank reviews Michael's full asset picture. With £255,000 total savings (31.9% deposit), he needs a £545,000 mortgage — 5.45× salary. The private bank approves up to 5.5× for clients with significant investable assets, treating the ISA as collateral for their affordability model. His repayment of £3,000/month is 42% of his take-home on £100k — challenging but achievable with his financial discipline and no other debt.
