The short answer

On the £460,000 Sawston average, a 5% deposit is £23,000, 10% is £46,000 and 15% is £69,000. The gap between those three numbers usually decides your interest rate, not your application.

Where the rate bands sit on a Sawston purchase

Lenders price in bands. Crossing from 95% to 90% borrowing, then to 85%, usually moves you to a cheaper rate. On the local average those thresholds are £23,000, £46,000 and £69,000.

The monthly difference is real. Borrowing 95% costs about £2,555 a month on our illustration, against £2,286 at 85%. That is £3,227 a year, before any rate difference between the bands is counted.

How long saving actually takes here

Buying at the £460,000 Sawston benchmark needs household income of about £102,000, on the lending multiples used in our town guide. A household on that income saving a tenth of it puts away £10,200 a year.

At that rate a 10% deposit of £46,000 takes about 5 years.

Fees, duty and the rest of the cash pile

The deposit is not the only cash you need. Budget for survey, conveyancing, searches and moving.

Band D council tax in Cambridgeshire is £2,562 a year, and lenders count committed outgoings when they size your loan.

An income requirement near £102,000 puts this firmly in two income territory. A single buyer is unlikely to reach the benchmark price without a large deposit or family help.

Questions people ask

How much deposit do I need to buy in Sawston?
Five percent of the £460,000 average is £23,000. Ten percent is £46,000. More deposit usually means a cheaper rate band rather than simply a smaller loan.
Can I buy with a 5% deposit here?
Often yes, subject to income and credit. Expect a higher rate than at 90% or 85%. On our illustration the monthly gap between 95% and 85% is about £269.
Does a bigger deposit beat a longer term?
Usually. A bigger deposit cuts both the rate and the balance. A longer term only spreads the same debt over more years and costs more interest overall.
How do I check broadband speed at a property in Sawston?
Use Ofcom's free broadband and mobile checker at checker.ofcom.org.uk. Enter the property's postcode and choose the address to see which broadband speeds and mobile coverage are available before you make an offer.
