First Time Buyers Mortgage Guide: 2025

Last updated Mar 16, 2026

Let us help you to navigate the world of mortgages by answering some of the most common questions we get asked by First time buyers.

What is a mortgage?

A mortgage is usually a loan sanctioned against an asset like a house or a commercial property. The lender keeps the asset as collateral until the borrower repays the total loan amount.

What are the different types of mortgages? 

Capital Repayment

The vast majority of residential mortgages are capital repayment. This means that you are reducing your overall debt, with interest paid on the amount of the decreasing balance. At the end of the mortgage term, the balance will be £0, and the property will be debt-free. A property with no mortgage secured against it is known as unencumbered.

Interest Only

Only the interest is paid on an interest-only mortgage. This means that the overall debt balance does not decrease, you will owe the same amount at the end of the term as you did on day 1 of the loan. There are strict FCA rules around interest-only mortgages and lenders will only accept your application if you can demonstrate a robust strategy for repaying the debt in full at the end of the mortgage term.

Part Interest Part Repayment

As the name suggests, part of the mortgage is on capital repayment, part of the mortgage is on interest only. The capital repayment part of the mortgage will reduce, but as above, you will need to provide a robust strategy for repaying the interest-only debt at the end of the term.

What is stamp duty?

You must pay Stamp Duty Land Tax (SDLT) to the government if you buy a property or land over a certain price in England and Northern Ireland. Your solicitor will usually calculate this on your behalf at the point of completion, adding the amount due to their fee.

What affects the mortgage rate offered to first time buyers?

Many variables impact the mortgage rate that you may have access to such as house price, loan to value, and your credit history.

What are mortgage fees? (different from professional fees)

Some mortgage products will include an arrangement or set-up fee for your mortgage. Whilst researching the market on your behalf, New Mortgage finance includes fees in any cost calculation, analysing the ‘true cost’ of each available mortgage and recommending the best fit for you.

Most mortgage lenders will allow you to add this fee to the loan, but this will mean you pay interest on it for the whole mortgage term.

What rate will I get as a first time buyer?

Every mortgage application is different, and the rates you receive are dependent on your specific circumstances.

Generally, the lower the LTV, the lower the rate. The best rates are available once LTV drops below 60%.

What does LTV mean?

LTV = Loan to value. This is the ratio between the value of the property being mortgaged, and the size of the mortgage being secured against it. 

A £60,000 mortgage on a house worth £100,000 would result in a LTV of 60%.

Typically, the lower the LTV, the smaller the risk for the mortgage lender, and the better the rate you will receive. 

How much deposit do I need to have saved?

The minimum you will need is 5%, although the product range is very limited. A 10% deposit will give us a larger range of product options from which to recommend. The bigger the deposit, the better the rate, see LTV above.

What is equity?

Equity is the proportion of a property that does not have a mortgage secured against it. eg. A £100,000 house mortgaged at £60,000 would have £40,000 equity.

What is a decision in principle or an agreement in principle?

A decision in principle (DIP) or agreement in principle (AIP) is a document that states the level of mortgage borrowing available to you based on your income and credit history. The level of available borrowing can change once a full Fact Find has been completed and your case has been underwritten by the lender.

What is underwriting?

Mortgage underwriting is the process a lender uses to determine if the risk of offering a mortgage to a particular borrower is acceptable and is a part of the mortgage application process.

How quickly will my purchase complete?

It can take around 6 months to buy a house, but this varies from move to move. On average it’s 20-90 days to find a house, 15-30 days to receive a mortgage offer, 20-30 days for solicitors to exchange contracts then 10-30 days to complete and get the keys.

What is the exchange of contracts?

Exchanging contracts is the penultimate step in a house purchase, occurring after a solicitor has carried out all necessary searches and there is agreement to the contract terms – it is followed by completion, when you get the keys and the house is yours. Once each party has signed the contracts and they have been exchanged, they are binding. If something catastrophic happened to the house (eg a fire) between exchange and completion you would still be legally bound to complete the purchase so it is important that property insurance is in place at the point of exchange.

How much does it cost to buy a house?

In addition to the cost of the property, you will be responsible for-

Lenders Arrangement fee – £0-2500.

Lender Valuation fee – £0 – £700

Property Survey – £400- £1,500

Broker fee – £495 – £995

Removal Costs – £50 – £1,500

Conveyancing (inc land registry, searches etc etc) – £750 – £1,000

Stamp Duty – https://www.gov.uk/stamp-duty-land-tax

TOTAL – £1,695 – £8,195 + STAMP DUTY

What’s the longest mortgage (term) a first time buyer can have?

Lenders are offering terms to younger customers up to 40 years. But you should always consider that a longer term will mean that you will pay more interest, and pay more overall. As part of our service, we can talk you through payment projections over different term lengths, demonstrating how much interest can be saved by shortening your term.

Can my parents guarantee my mortgage?

Often referred to as a JBSP mortgage, a joint borrower sole proprietor mortgage allows a parent (or family member) to contribute to their son or daughter’s mortgage without being a co-owner. Their income and circumstances would be factored into the mortgage application, increasing the level of borrowing possible. This is sometimes known as a guarantor mortgage.

I’ve been given some money for a deposit, how does it work?

Many FTBs utilise gifted deposits. Gifted deposits are very common and don’t normally cause any issues with lenders. The individual providing the gift will be required to sign a declaration that the money is a gift, with no expectation of repayment.

Can I fix my payments long-term?

Rates can be fixed when taking out a new mortgage, typically for 2,5 or 10 years.

When on the first rungs of the property ladder – it might make sense to fix for a shorter period. If your property increases in value, so does your share of equity- this lowers your LTV meaning you could get a better deal when renewing. You might not get this opportunity to switch to a cheaper product if you fix long term.  

Remember – if you exit a mortgage whilst in a fixed-rate period, your lender will enforce an early repayment charge (ERC). This can be as much as 5% of your total loan. Always keep this in mind when fixing for longer periods, as making changes down the line can become very expensive!

What happens at the end of my fixed rate period? 

NM Finance will contact you approximately 4 months prior to the end of your fixed rate period. At this point we will complete a new fact find, recording any changes in your circumstances before researching the entire mortgage lender market, finding and arranging the best product for you to move to. This is called a re-mortgage. If a new product is not arranged you will revert to you lender’s standard variable rate (SVR) which is usually significantly higher than a preferential rate, resulting in a large uplift in the monthly payment amount.

When should I get a mortgage? (ie at what point in the process of buying a property?)

It’s prudent to make initial enquiries as soon as you think about buying a house or moving- without making initial enquiries you won’t know how much you can borrow, and what house you can afford.

What does affordability mean and why is it important for first time buyers?

Affordability is a calculation used by a lender to ascertain if you can afford, based on income and existing commitments, the mortgage you are applying for.

How much can I borrow?

There are many variables that impact the level of borrowing available to you, such as your income, existing credit commitments, credit history and individual circumstances. Lenders typically allow up to 4.5x income. If you are applying alone, this will be your income only, if you are buying with someone else, multiples of your combined income will be used to calculate the total mortgage available to you.

Credit History

Lenders will review all of your existing credit commitments as part of the application process. Any commitments that you already have may impact the total mortgage available to you. This includes, but is not limited to; car finance, credit cards, loans, store cards & finance. Your conduct around these commitments is also considered – missed or late payments will negatively affect your application. Mortgage calculators or comparison sites may not factor existing credit into initial results, you should not make any financial commitments until a full fact find has been completed by an experienced mortgage broker to calculate your exact level of borrowing. 

Are there specialist first time buyer mortgages available?

Shared Ownership

Shared Ownership is a government scheme to help people with smaller deposits get on the property ladder. You can apply to buy a portion of your property, and then you pay rent on the remaining portion. If you want to gradually increase how much of the property you own, you can ‘staircase’ – buying more of it in chunks until you own the whole thing.

Help to Buy

Help to Buy is a government-backed scheme that aims to help first time buyers onto the property market.

Help to Buy provides eligible buyers with an equity loan (also known as shared equity) of up to 20% of the value of a new build home. The government provides the 20% loan so the buyer only needs to raise a 5% deposit, with a 75% mortgage making up the rest.

You should always bear in mind the long-term consequences of shared equity. After 25 years of the loan period, you will be required to pay it off in full. As an equity loan, the loan will be proportionate to the value of the property at the time 25 years on rather than a fixed figure, which means you could be paying back significantly more than you first borrowed.

Do I have to talk to the in-house broker at the estate agent?

No, you do not. Some estate agents will insist you to talk to their broker, but you are under no obligation to do so. It’s worth bearing in mind that some estate agent brokers can only recommend from a limited panel of lenders, meaning they may not have access to the best deal for you.

Give the estate agent NM Finance’s details, and we can provide them with the documentation that proves that you can afford that amount you are offering for the property – this document is called a DIP or AIP.
