How This Tool Works
📋 Purpose
Use this tool to find the minimum number of years you'd need to stay in a property for buying to be cheaper than renting — based on real data for your area, not national averages.
⚙️ How It Works
- 1Enter your postcode — we look up real sold prices from the HM Land Registry for your area
- 2Set your deposit, how long you plan to stay, and whether you're a first-time buyer (affects Stamp Duty)
- 3We calculate your break-even year using the live Bank of England base rate and regional rent estimates
- 4Review the 30-year cumulative cost chart and full breakdown to make an evidence-backed decision

Quick Tips
Jump-start your understanding with these essential tips
Different UK regions have dramatically different price-to-rent ratios. London and the South East often favour renting at typical timescales; the Midlands and North can favour buying sooner. Use your real postcode for accurate results.
If you plan to stay longer than the break-even year, buying tends to win. If you might move before then, renting is typically cheaper — even accounting for equity growth.
Selling costs (estate agent fees, conveyancing) are not factored in. If you plan to sell within a few years, your true buying cost will be higher than shown. Scroll to the assumptions card for a full list.
Step-by-Step Guide
Follow these steps to get the most from this tool
We use your postcode to look up real recent sold prices from the HM Land Registry for your immediate area. If no recent sales are found, we fall back to the ONS regional average for your wider region. The data quality badge tells you which source was used.
📊 Land Registry data is typically 2-3 months old (historical records of actual sales). This doesn't affect accuracy — we use real market conditions, not live listings.
💡 Pro Tips:
- •Full postcode (e.g. SW1A 1AA) gives the most accurate Land Registry match.
- •Outer districts (e.g. SW1A) still work — we use the regional average if no local sales are found.
Leave deposit blank to use 15% of the local average price. Choose how many years you plan to stay — this is the most important input, because the break-even year determines which path wins for you. First-time buyer status affects Stamp Duty (SDLT) — you pay £0 on the first £425,000 as a first-time buyer.
💡 Pro Tips:
- •Planning to stay fewer than 5 years? Renting usually wins in most UK regions.
- •The mortgage term affects your monthly payment but not your break-even year much — longer terms lower monthly costs but increase total interest paid.
The hero card shows: (1) the break-even year — when buying becomes cheaper than renting in total over time, (2) our recommendation based on whether your planned stay exceeds that break-even, and (3) your projected equity at your chosen time horizon. Scroll down for the 30-year cumulative cost chart and full cost breakdown.
💡 Pro Tips:
- •The chart shows buying costs in indigo and renting in green — see exactly where they cross.
- •Use "Export as CSV" to save the full calculation for your records or a mortgage advisor meeting.

We apply the standard SDLT bands: 0% on the first £250,000, 5% on £250k–£925k, 10% on £925k–£1.5m, and 12% above that. First-time buyers get relief: 0% up to £425,000 and 5% on £425k–£625,000. Properties over £625,000 do not qualify for first-time buyer relief. Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT) — both differ from SDLT. We use SDLT as a UK-wide approximation; the assumptions card flags this clearly.
The Bank of England base rate is the rate at which the BoE lends to commercial banks. High-street lenders add a margin on top to cover their costs and profit. A 1.5% margin is a conservative estimate for a standard 75–85% LTV 2-year or 5-year fixed deal. Your actual rate will depend on your credit score, deposit size, and the specific product you choose. The tool shows the base rate source (live or fallback) and the effective mortgage rate used.
