Before You Buy Your First Home: The Hidden Costs That Catch Buyers Out

Why first-time buyers underestimate the real cost

Most first-time buyer guidance focuses on the deposit — typically 5 to 20 percent of the purchase price. The additional costs of actually completing the purchase are less prominently discussed and are frequently underestimated. A first-time buyer purchasing a £250,000 property with a 10 percent deposit needs £25,000 in savings for the deposit alone. The additional buying costs on top of that deposit can easily reach £10,000 to £15,000, meaning the total cash required is £35,000 to £40,000 before a single item of furniture is purchased.

Stamp duty land tax for first-time buyers

Stamp Duty Land Tax is charged on residential property purchases in England and Northern Ireland. Scotland charges Land and Buildings Transaction Tax and Wales charges Land Transaction Tax — different rates and thresholds apply in each nation. In England, first-time buyers currently benefit from relief on the first £425,000 of a property valued up to £625,000. Above £425,000 the standard rate of five percent applies up to £625,000. Properties above £625,000 do not qualify for first-time buyer relief and standard rates apply from the first pound.

These thresholds applied from September 2022 and were scheduled to revert to lower thresholds in April 2025. Check the current thresholds at gov.uk/stamp-duty-land-tax before budgeting, as the figures change with government policy. Budget for the stamp duty based on the current rate and have a contingency in case the rate changes between offer and completion.

Conveyancing and legal fees

A solicitor or licensed conveyancer handles the legal transfer of ownership. Fees vary significantly between firms, ranging from approximately £1,000 to £3,000 for straightforward purchases. The solicitor's own fees are only part of the total conveyancing cost — disbursements add further amounts including local authority search fees (£250 to £500), Land Registry fees (£20 to £500 depending on property value), electronic transfer fees, drainage searches and environmental searches.

A leasehold property adds additional conveyancing complexity and cost. The solicitor must review the lease, obtain a leasehold information pack from the freeholder or managing agent, and advise on any unusual lease terms. Leasehold conveyancing typically costs £300 to £800 more than freehold.

Survey costs and what each level covers

A mortgage lender's valuation is not a survey. It confirms to the lender that the property is adequate security for the loan — it does not identify defects or advise the buyer. A buyer who relies on a lender's valuation alone has no independent professional assessment of the property's condition.

RICS offers three levels of survey. A RICS Level 1 Condition Report gives a basic overview of condition using a traffic light system — suitable only for new builds and conventional properties in good condition. A RICS Level 2 HomeBuyer Report provides a more detailed assessment of condition and market value and is appropriate for most conventional properties. A RICS Level 3 Building Survey is the most comprehensive assessment, recommended for older properties, those in poor condition, or properties with unusual construction. Level 2 surveys cost £400 to £800; Level 3 surveys cost £600 to £1,500 or more depending on property size and location.

Mortgage costs beyond the interest rate

The advertised interest rate is not the only cost of a mortgage. Arrangement fees — charged by the lender to set up the mortgage — range from zero to £2,000 and can be added to the mortgage balance or paid upfront. Adding the fee to the balance means paying interest on it for the mortgage term, which increases the total cost. Broker fees may apply where you use a mortgage broker — whole-of-market brokers may charge a fee of £300 to £500 or receive commission from lenders. Mortgage protection insurance — life cover and income protection — is not legally required but is strongly advisable and adds to monthly costs.

Ongoing costs that first-time buyers frequently miss

Buildings insurance is required by the mortgage lender from exchange of contracts. Contents insurance covers possessions inside. Service charges on leasehold flats cover building maintenance and management, and can be several thousand pounds per year. Ground rent on pre-2022 leases may be payable annually. Council tax is payable from the date of completion. Utility connection and setup costs apply in properties where accounts need to be established.

Maintenance and repair costs are often overlooked entirely. A property that requires a new boiler within a year of purchase (replacement costs £2,000 to £4,000), roof repairs or significant redecoration will create costs that a first-time buyer budget needs to accommodate. Having a financial buffer of at least three to six months of mortgage payments after all purchase costs is advisable before proceeding.

Frequently asked questions

Do first-time buyers pay stamp duty in England?

First-time buyers in England pay no stamp duty on the first £425,000 of a property priced up to £625,000. On the portion between £425,000 and £625,000, five percent applies. Properties above £625,000 do not qualify for first-time buyer relief. Check current thresholds at gov.uk/stamp-duty-land-tax as these change with government policy.

Can I add mortgage fees to my mortgage?

Most lenders allow arrangement fees to be added to the mortgage balance rather than paid upfront. This avoids an immediate cash outlay but means paying interest on the fee for the mortgage term. On a £1,500 fee over 25 years at four percent, the total interest cost is approximately £1,050 — making the effective fee around £2,550. Compare the true cost before deciding.

Is a survey compulsory when buying a home?

A full survey is not legally compulsory. A mortgage lender's valuation is required by the lender but does not protect the buyer. Getting a survey is strongly advisable — a Level 2 HomeBuyer Report costs £400 to £800 but can identify defects worth thousands of pounds and give grounds for renegotiating the purchase price.

What is the difference between exchange and completion?

Exchange of contracts is when the purchase becomes legally binding and the deposit is paid. Completion is when ownership transfers, the purchase price is paid and keys are handed over. Buildings insurance must be in place from exchange, not completion. The gap between exchange and completion is typically one to four weeks.

What ongoing costs should I budget for after buying?

Budget for buildings and contents insurance, council tax, utility bills and service charges if leasehold. Set aside a maintenance reserve — financial advisers commonly recommend one to two percent of property value per year for maintenance. Have an emergency fund of at least three to six months of mortgage payments before completing.
