Questions people ask

How much deposit do I need to buy in Merton Park?
Five percent of the £825,000 average is £41,250. Ten percent is £82,500. 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 £482.
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 Merton Park?
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.
