Add a safety margin A Mortgage in Principle is often based on incomplete information — fees, exact service charges, and full underwriting checks come later. If you offer right at your absolute maximum, there's no room left if something changes, and a sale can fall through post-offer. A margin gives you genuine room to negotiate and a buffer against surprises.

What a different term would mean

Assumes a repayment mortgage at one constant rate for the whole term. Most real deals reset after 2–5 years, so your actual payments will change. Click a term in the table to switch to it.
This is a general information tool, not financial or mortgage advice. Figures are estimates based on typical UK lending criteria and publicly reported lender ranges as of 2026, and will vary by individual lender, credit profile, and circumstances. Service charge figures are modelled estimates, not real data lookups. Always confirm affordability and property-specific costs with a qualified, whole-of-market mortgage broker before making an offer.

Can you get a mortgage on this property?

Your budget says what you can borrow in general. Lenders also judge the property itself: the lease, the block, how it's built, what's below it. Enter what the listing or agent tells you and we'll check it against lenders' published rules and recent local sales.

Is buying actually the right move yet?

Rent vs buy, on your numbers

Buying isn't automatically the better financial decision — it depends on how long you stay. Upfront costs and mortgage interest weigh heavily in the early years, and the deposit you tie up could be invested instead. This shows the year buying overtakes renting for your situation. It's information, not a recommendation.

Not financial advice. This is a simplified model to help you think through the trade-off, not a recommendation to buy or wait. It cannot account for your personal circumstances, risk tolerance, or non-financial factors like stability and control over your home. Speak to a qualified financial adviser before making a decision based on this.
Assumes: stamp duty at first-time-buyer rates, ~£2,500 legal and survey costs, maintenance at 1% of property value per year, your service charge figure above, and rent rising 3% a year. Whichever option costs less in cash each year, that difference is assumed to be invested at your chosen rate — plus any additional monthly savings you've specified above — this is what makes early years often favour renting, since mortgage interest is heaviest then. Every assumption varies in reality; treat this as a way to see how the trade-off moves, not a precise prediction.
What this doesn't account for
  • Capital Gains Tax on investment returns, if you invest the difference rather than buying
  • Income tax on any rental income, if you ever let out part of the property
  • The cost of moving more than once during the period
  • Household bills like electricity, gas, and water — these apply to both scenarios and aren't modelled here
  • Inflation on day-to-day living costs — all figures are in today's money terms
  • The personal and lifestyle value of owning your own home, which isn't a financial number at all
