Use this page to compare first-time assumptions with fallback scenarios before final offers.
In brief
- Test first-time and fallback scenarios.
- Model nearby prices before final bidding.
- Keep assumptions evidence-based.
- Confirm relief treatment before exchange.
A £350,000 first-time buyer plan should test both relief assumptions and fallback scenarios before final offers.
Use this guide to compare first-time assumptions with moving-home baselines and maintain offer discipline at £350,000.
Worked examples — home mover typical fees
| Price | England/NI tax | Scotland tax | Wales tax |
|---|---|---|---|
| £300,000 | £5,000 | £4,600 | £4,500 |
| £500,000 | £15,000 | £23,350 | £18,000 |
| £750,000 | £27,500 | £48,350 | £36,750 |
Why £350,000 is a practical first-time benchmark
This level is common in first-home searches and often used for initial offer planning.
Relief assumptions can affect outcomes, but they should never be treated as guaranteed without checks.
A conservative fallback scenario reduces decision risk.
How to compare scenarios properly
Run £325,000, £350,000 and £375,000 under first-time settings.
Then compare against moving-home assumptions at the same prices.
Use differences to set a realistic offer ceiling and contingency buffer.
Evidence and execution checks
Document eligibility assumptions early and seek legal confirmation.
Update fees from real quotes rather than defaults.
Recalculate if negotiated price changes before exchange.
Decision framework used by careful buyers
Start with an offer ceiling based on total cash, not headline house price. In practice, buyers who only track deposit and mortgage payments can miss the transaction-cost layer, which is exactly where completions become stressful.
Use a three-pass approach: first estimate tax by nation and buyer type, then add realistic fees, then pressure-test the result by increasing the offer by £10,000 and £25,000. This shows how sensitive your budget is before bidding.
Treat the model as a planning instrument. Final legal liability always sits with official calculators and your conveyancer’s completion statement, but early visibility reduces avoidable surprises.
Practical checklist before making an offer
Confirm your likely buyer status first (home mover, first-time buyer, or additional property). Switching status can alter tax materially at the same price point, so this should be fixed before negotiating.
Collect at least two conveyancing quotes and check what is included. Buyers often compare legal fees without checking disbursements, search packages, leasehold supplements or transfer fees.
Keep a contingency buffer instead of budgeting to the exact minimum. A modest reserve can protect timelines when valuation, legal or lender admin costs move late in the process.
