FAQ
Frequently asked questions
Helpful answers to common questions about this calculator.
Is it cheaper to rent or buy in the UK?
The answer depends on property prices, mortgage rates, your deposit size, and how long you plan to stay. In many UK areas, monthly mortgage payments are comparable to rent, but buying has significant upfront costs.
What are the hidden costs of buying a home?
Beyond the mortgage, homeowners pay for buildings insurance, maintenance and repairs (budget 1-2% of property value annually), service charges for flats, and any ground rent on leasehold properties.
How long should I plan to stay to make buying worthwhile?
Generally, buying becomes more cost-effective than renting after 5-7 years, once you have recouped the upfront purchase costs. This varies significantly by location and market conditions.
Does property always go up in value in the UK?
While UK property prices have risen significantly over the long term, values can fall in the short term. Regional variations are substantial, and past performance does not guarantee future growth.
What about shared ownership as a middle ground?
Shared ownership lets you buy a 25-75% share of a property and pay rent on the remainder. It reduces the deposit needed and can be a good stepping stone to full ownership in expensive areas.
