Buying Your First Home: Mortgage to Completion
Buying your first home takes 6-12 months from serious house-hunting to keys in hand. Each step has cost, timing, and decision-points. This guide walks through them.
Estimated timeline
Build the deposit and check your credit
12-24 months savingMost first-time buyers need a 5-10% deposit. For a £250,000 home, that's £12,500-£25,000. Use a Lifetime ISA (LISA — £4,000/year, 25% government bonus up to age 50, must be 12+ months old, max property £450,000). Check your credit reports at all three agencies (free with Experian, Equifax, TransUnion). Fix errors. Avoid new credit applications in the 6 months before mortgage application. Save 1-2 years for legal fees, surveys, stamp duty (first-time buyer relief), and moving costs (~£3,000-£8,000).
Get a Decision in Principle (DIP)
1-2 weeksSpeak to a whole-of-market mortgage broker or use comparison sites. Mortgage broker fees range £0 (commission-only) to £500-£1,500 (fee + commission). The DIP is a soft-check estimate of what you can borrow. Useful for: searching properties in the right price bracket; signalling seriousness to estate agents. Valid 60-90 days. Get DIPs from 2-3 lenders to compare.
Find and offer on a property
4-12 weeks finding the right oneUse Rightmove, Zoopla, OnTheMarket. Filter on bedrooms, area, EPC rating, leasehold/freehold. Visit 10-20 properties to calibrate. When ready, make an offer through the estate agent — usually verbal then in writing. Below asking is common for slow markets; above for hot markets. The seller can reject, accept, or counter. Once accepted, the property is "sold subject to contract".
Conveyancing solicitor or licensed conveyancer handles the legal transfer (£800-£2,500). Get quotes — fixed fees are common. Survey: HomeBuyer Report (£400-£900) for most properties, full Building Survey (£600-£1,500) for older or unusual properties. Mortgage valuation is for the lender only and is not a survey for you. Pay early — surveys take 2-3 weeks to book and complete.
Mortgage application and offer
2-6 weeks from full application to offerSubmit full mortgage application (after DIP and offer accepted). Lender does hard credit check, full affordability calculation, valuation. Mortgage offer issued after 2-6 weeks, typically valid 6 months. Read the offer carefully — interest rate, fixed/variable, term, fees, early repayment charges. The mortgage offer is binding on the lender (subject to material change in circumstances).
Conveyancing searches and enquiries
6-12 weeksYour solicitor orders: Local Authority search (planning issues, road schemes, contaminated land — £100-£300), Environment search (flood risk, ground stability), Water/Drainage search, Chancel Repair search. They review the contract from the seller's solicitor, raise enquiries about anything unclear, and check title. This stage can take 6-12 weeks. Push your solicitor for updates weekly.
Exchange of contracts: both sides sign and lock in. From this point, neither side can back out without legal penalty (10% of price typically). 5-7 days later (or longer if agreed): completion. The mortgage funds are sent. Your solicitor confirms completion. You collect the keys from the estate agent. Stamp Duty Land Tax (SDLT) is paid within 14 days — first-time buyer relief means £0 SDLT on properties up to £425,000 (2025-26 rates).
After moving in
Week 1 admin; 1-2 months to feel settledNotify your bank, employer, HMRC, DVLA, GP, schools, council tax (single occupier discount if applicable). Set up direct debits for mortgage, council tax, utilities. Get buildings insurance from completion day (the lender requires it). Get contents insurance. Register on the electoral roll. Update the Land Registry title — your solicitor handles this. Keep ALL documents — the title deeds, mortgage offer, completion statement, surveys — together for the future.

Right to Buy and Right to Acquire
The Right to Buy scheme gives most council tenants in England the legal right to purchase their home at a significant discount. A separate but similar scheme — Right to Acquire — applies to some housing association tenants. Both schemes have been in place for decades and have enabled millions of social tenants to become homeowners, but they come with important conditions and restrictions that buyers need to understand before applying.

Shared Ownership
Shared ownership is a government-backed scheme that helps people buy a home they could not otherwise afford by purchasing a share of the property (initially between 10% and 75%) and paying rent on the remaining share to a housing association. Over time, buyers can increase their ownership share — a process called staircasing — until they own the property outright. The scheme has been significantly reformed since 2021, with important improvements for buyers.

Mortgage Arrears and the Pre-Action Protocol
Falling behind on mortgage payments is frightening, but lenders are required to follow strict procedures before they can repossess your home. The Pre-Action Protocol for Possession Claims based on Mortgage or Home Purchase Plan Arrears means that courts will expect both you and your lender to take reasonable steps to resolve arrears before a possession order is made. Acting early and engaging with your lender greatly improves your chances of keeping your home.

Leasehold and Service Charge Disputes
Owning a leasehold property means owning the property for a fixed term while the freehold — the land — is owned by someone else (the freeholder or landlord). Leaseholders pay ground rent (now largely abolished for new leases) and service charges for the maintenance and management of the building. Disputes about service charges, management quality, and lease terms are common, but leaseholders have legal rights and access to the First-tier Tribunal (Property Chamber) to resolve them.
