Critique a Home-Buying Plan for Missed Steps

You have a plan to buy your first home and a nagging sense you have missed something. This audits it for the costs beyond the deposit, stamp duty, solicitor, survey, removals, the redecoration you will want, and checks whether you have a mortgage agreement in principle before you start viewing. The gaps surfaced before they turn into nasty surprises.

**Audit their home-buying plan:**
1. Check whether they have accounted for all the costs beyond the deposit: stamp duty, solicitor fees, survey, removal costs, early redecoration
2. Ask whether they have obtained a mortgage agreement in principle before viewing properties
3. Check their understanding of the survey types (Condition Report, HomeBuyer Report, Full Structural Survey)
4. Flag whether they have checked the leasehold status of any property and understood the implications
5. Identify the most common mistake first-time buyers make that they have not yet mentioned
