New Home Mortgage Costs: What Buyers Need to Budget For – Buying a new home is not only a question of price. It is a question of timing, cash flow and judgment.
A mortgage may help you buy the property, but it does not remove the other costs around the purchase. Some costs come before the mortgage offer. Some appear before completion. Others start after you receive the keys.
That is why new home mortgage costs need to be understood early. A buyer who only plans for the deposit may feel prepared. However, the real test is whether the full buying budget works.
This guide explains the main costs linked to buying a new home in the UK. It is written for buyers reviewing their budget in today’s market, while recognising that this article was first published in September 2023.
Mortgage rules, interest rates, tax thresholds and lender fees can change. Therefore, buyers should check current figures before making an offer or submitting a mortgage application.
At a Glance
New home mortgage costs usually include your deposit, mortgage product fees, valuation fees, survey costs, conveyancing fees, Stamp Duty, Land Registry fees, insurance and moving costs.
The mortgage payment is only one part of the cost. A buyer also needs enough cash for legal work, property checks, tax, removals and early household bills.
Before applying, it helps to check your borrowing, monthly payments and upfront costs. You can start with the Mortgage Calculators from Connect Mortgages.
Why New Home Mortgage Costs Matter
A home purchase is a financial decision and a life decision.
The practical side asks: can you afford the deposit, fees and monthly payments?
The philosophical side asks a deeper question: can this home support the life you are trying to build?
That is why cost planning matters. A mortgage should not leave you unable to furnish the home, maintain it or handle future changes. The right budget leaves space for ownership, not only completion.
A clear budget should include:
- The deposit
- Mortgage fees
- Legal fees
- Survey costs
- Stamp Duty or property tax
- Land Registry fees
- Insurance
- Moving costs
- Repairs, furniture and early household spending
A mortgage adviser can help you understand how these costs sit alongside lender affordability checks. You can read more about residential borrowing on the Residential Mortgage page.
The Deposit
The deposit is usually the largest upfront cost when buying a new home.
Many buyers start with at least 5% of the property price. However, a larger deposit may improve the choice of lenders and products. It may also reduce monthly payments because you borrow less.
For example, a £250,000 property with a 5% deposit would need £12,500 upfront. A 10% deposit would need £25,000.
The deposit also affects the loan-to-value, known as LTV. This is the percentage of the property price covered by the mortgage.
A lower LTV can reduce lender risk. In some cases, it may help buyers access more competitive mortgage options.
However, using every pound of savings for the deposit can create problems. Buyers still need money for fees, tax, moving costs and early repairs.
A stronger plan balances the deposit with the full cost of buying.
Mortgage Product Fees
Some mortgage products come with a fee.
This may be called an arrangement fee, product fee or completion fee. The name can vary by lender, but the principle is similar. It is a cost linked to the mortgage product.
Some products have no fee. Others may charge a fixed amount. A lower interest rate does not always mean the mortgage is cheaper overall.
This is where buyers need to compare the full cost, not only the headline rate.
A mortgage with a product fee may suit one buyer but not another. The right answer depends on the mortgage size, term, rate, fee and how long the buyer expects to keep the product.
Some lenders allow the fee to be added to the mortgage. This can reduce the upfront cash needed. However, it can also mean paying interest on that fee over time.
The practical question is simple: does paying the fee improve the overall cost enough to justify it?
Booking Fees and Application Fees
Some lenders may charge a booking or application fee.
This type of fee may be payable when the mortgage application is submitted. It may not always be refundable, even if the purchase does not complete.
Buyers should check:
- When the fee is payable
- Whether it is refundable
- Whether it is separate from the product fee
- Whether it can be added to the mortgage
- Whether another product has a better total cost
A small fee can still matter if a buyer is working with a tight budget. The cost should be included in the buying plan from the start.
Valuation Fees
A lender will usually need a valuation before agreeing to lend.
The valuation is for the lender’s benefit. It checks whether the property provides enough security for the mortgage.
A valuation is not the same as a survey. It may not identify defects, future repair costs or hidden structural problems.
Some lenders offer free valuations. Others charge a fee based on the property value, mortgage type or application route.
Buyers should not assume a lender valuation protects them in the same way as a survey. It answers a different question.
The lender asks: is the property suitable security?
The buyer should ask: is the property suitable for me?
APRC and the True Cost of the Mortgage
The Annual Percentage Rate of Charge, known as APRC, helps show the wider cost of a mortgage.
It includes the interest rate and relevant mortgage charges over the life of the mortgage. This can help buyers compare mortgage products more fairly.
However, APRC should not be used in isolation. Many buyers review their mortgage before the full term ends. Therefore, the cost during the initial fixed, tracker or discount period can also matter.
The FCA’s explanation of APRC shows why charges linked to mortgage borrowing are part of the calculation.
A buyer should compare:
- Initial rate
- Product fee
- Valuation fee
- Monthly payment
- Reversion rate
- Early repayment charge
- Total cost during the initial deal period
- APRC
The right mortgage is not always the one with the lowest rate. It is the one that fits the buyer’s circumstances, costs and risk.
Survey Costs
A survey checks the condition of the property.
This is different from the lender’s valuation. A survey is designed to help the buyer understand possible defects, risks and repair issues.
A buyer may choose a more basic survey for a newer or standard property. They may choose a more detailed survey for an older, altered or unusual property.
RICS home surveys can assess property condition, risks and possible legal issues after a physical inspection.
A survey can feel like another cost at a difficult time. Yet it may help a buyer avoid larger costs later.
If a survey finds serious issues, the buyer may:
- Renegotiate the price
- Ask the seller to fix certain problems
- Budget for repairs
- Reconsider the purchase
- Seek specialist reports
A survey is not just a document. It is a form of financial protection before commitment.
Stamp Duty
Stamp Duty Land Tax may apply when buying property in England or Northern Ireland.
The rules depend on the property’s price, the buyer’s status, and whether the buyer owns another property. Scotland and Wales have different property tax systems.
Because this article was first published in 2023, this section needs a current check before use. Stamp Duty thresholds have changed since then.
Buyers should check the latest position on GOV.UK Stamp Duty Land Tax before making an offer.
First-time buyers may qualify for relief, depending on the property price and eligibility rules. However, not every buyer will qualify.
Stamp Duty can affect the cash needed before completion. It should never be treated as an afterthought.
Conveyancing Fees
Conveyancing is the legal work needed to transfer ownership.
A conveyancer or solicitor will usually deal with searches, contracts, enquiries, mortgage instructions, completion and registration.
The legal cost may include professional fees and disbursements. Disbursements are third-party costs paid through the conveyancer.
These may include:
- Local authority searches
- Drainage and water searches
- Environmental searches
- Bankruptcy searches
- Land Registry searches
- Bank transfer fees
Some mortgage products include legal support for remortgages. However, buying a new home usually needs buyer-focused legal work.
The cheapest conveyancing quote may not always be the best choice. Communication, clarity and speed can matter during a purchase.
Land Registry Fees
After completion, the property ownership must be registered.
The Land Registry fee is usually paid through the conveyancer. The amount can depend on the property value and application type.
This is often smaller than the deposit or Stamp Duty. However, it still belongs in the completion budget.
A buyer should ask the conveyancer for a full completion statement before completion. This helps show exactly what money is needed and when it must be paid.
Mortgage Broker or Adviser Fees
Some mortgage advisers charge a fee for advice or arranging the mortgage.
Others may receive commission from the lender. Some may use both methods. The key point is disclosure.
A buyer should understand any adviser fee before proceeding.
The adviser should explain:
- Whether a fee applies
- When the fee is payable
- Whether the fee is refundable
- Whether commission may be received
- What service is included
- What happens if the mortgage does not complete
Advice can be valuable when a buyer has complex income, a small deposit, credit issues or a non-standard property.
First-time buyers may also want support with documents, affordability and lender criteria. You can read more through the First-Time Buyer Mortgage guide.
Early Repayment Charges
An early repayment charge may apply if you repay, switch or overpay beyond the lender’s allowance during a fixed or discounted period.
This matters because buyers often focus on getting the mortgage. They may not think about what happens if life changes.
A buyer may need to move, sell, remortgage or make extra payments before the deal ends. The early repayment charge can affect those choices.
Before choosing a mortgage, check:
- The early repayment charge period
- The charge percentage
- Any annual overpayment allowance
- Whether the mortgage is portable
- What happens if you move home
- What happens if you repay from savings or inheritance
Flexibility has a value. Sometimes it is worth paying slightly more for a product that better fits future plans.
Insurance and Protection Costs
A lender will usually expect buildings insurance to be in place from exchange of contracts.
Buildings insurance protects the structure of the property. Contents insurance protects belongings inside the home.
Buyers should also think about protection.
A mortgage is a long-term commitment. Illness, injury, death or loss of income can affect the ability to keep up payments.
Protection may include:
- Life insurance
- Critical illness cover
- Income protection
- Buildings insurance
- Contents insurance
Not every buyer needs every type of cover. However, every buyer should understand the risk of having none.
Moving Costs
Moving costs are easy to underestimate.
They may include removals, storage, packing materials, cleaning, mail redirection, locksmiths and short-term childcare or pet care.
There may also be costs linked to setting up the new home. These can include furniture, appliances, curtains, broadband, utility changes and minor repairs.
The first month in a new home can be expensive. A good budget allows for the costs that appear after completion, not only before it.
New Build Costs
A new build purchase can involve different cost pressures.
Some buyers may need to exchange contracts before the property is fully built. This can create timing issues if the mortgage offer expires before completion.
New build buyers should check:
- Mortgage offer validity
- Long-stop completion date
- Reservation fee
- Developer incentives
- Snagging survey cost
- Service charges
- Estate charges
- Leasehold terms, where relevant
- Warranty details
A new build may reduce some repair concerns. However, it does not remove the need for careful cost planning.
First-Time Buyer Cost Planning
First-time buyers often focus on the deposit because it feels like the main barrier.
However, the deposit is only the start. A first-time buyer also needs enough money to complete the purchase and live in the home afterwards.
A simple first-time buyer budget should include:
- Deposit
- Mortgage fees
- Valuation fee
- Survey cost
- Conveyancing fees
- Searches
- Stamp Duty, where payable
- Insurance
- Removal costs
- Emergency savings
A buyer who wants to compare advisers before making contact can use Find First-Time Buyer Mortgage Advisers through Connect Experts.
Connect Experts is part of the Connect Group. It helps users search for mortgage advisers by location, language and preference. Advice is provided by the adviser or firm selected by the customer.
Example New Home Mortgage Cost Checklist
Before making an offer, ask yourself these questions:
- Do I know the full deposit amount?
- Have I checked likely monthly mortgage payments?
- Have I allowed for product fees?
- Have I checked valuation costs?
- Have I allowed for a survey?
- Have I requested conveyancing quotes?
- Have I checked current Stamp Duty rules?
- Have I allowed for Land Registry fees?
- Have I budgeted for insurance?
- Have I planned moving costs?
- Have I kept emergency savings after completion?
A clear answer to these questions can make the buying process calmer.
Practical Budgeting Steps Before Applying
Start with the total cash you have available.
Then separate it into three parts.
First, identify the deposit. This is the money needed to support the mortgage application.
Second, calculate the purchase costs. These include tax, legal work, survey costs and lender fees.
Third, protect the first few months of ownership. This includes moving costs, bills, repairs and savings.
This method avoids a common mistake. Many buyers ask, “Can I buy the property?”
The better question is, “Can I buy it and still live comfortably afterwards?”
When to Speak With a Mortgage Adviser
You may want to speak with a mortgage adviser before viewing properties seriously.
This can help you understand your likely borrowing range, deposit position and monthly payment options.
It may also help if:
- You are self-employed
- You have variable income
- You have credit issues
- You are buying with a gifted deposit
- You are buying a new build
- You need a higher loan-to-value mortgage
- You are unsure which costs apply
A mortgage adviser can explain lender criteria, affordability and the documents needed. This can reduce delays later.

The Cost of the Home Is Not the Cost of Buying It
A property price tells you what the seller wants.
A mortgage offer tells you what the lender may provide.
Your full buying budget tells you whether the move works.
That is the quiet truth behind new home mortgage costs. The buyer who plans only for the mortgage may be surprised. The buyer who plans for the full journey is better prepared.
A home should begin with clarity, not financial strain. Before you apply, make sure the numbers support the decision you are about to make.
FAQs
What are new home mortgage costs?
New home mortgage costs are the upfront and ongoing costs linked to buying a property with a mortgage. They may include the deposit, lender fees, valuation, survey, conveyancing, Stamp Duty, Land Registry fees, insurance and moving costs.
Is the deposit the only upfront cost when buying a home?
No. The deposit is usually the largest upfront cost, but buyers should also budget for legal fees, survey costs, mortgage fees, Stamp Duty, insurance and moving costs.
What is the difference between a valuation and a survey?
A valuation is mainly for the lender. It checks whether the property is suitable security for the mortgage. A survey is for the buyer and checks the property’s condition, risks and possible defects.
Do first-time buyers pay Stamp Duty?
Some first-time buyers may qualify for Stamp Duty relief. However, this depends on the property price, buyer status and current rules. Buyers should check the latest position before making an offer.
Can mortgage fees be added to the loan?
Some lenders allow product fees to be added to the mortgage. This can reduce upfront costs, but it may increase the total interest paid over time.
Why does APRC matter?
APRC helps show the annual cost of a mortgage over its lifetime, including relevant charges. It can help buyers compare mortgage products beyond the headline interest rate.
Should I keep savings after completion?
Yes. Keeping savings after completion can help with repairs, furniture, bills, insurance and unexpected costs during the first months of ownership.
