You can call today to speak with our mortgage brokers rather than using the online mortgage calculator. We can explain what is required for a 300,000 mortgage.

What are the monthly payments on a £300,000 mortgage loan?

Each customer will have their own monthly payments of £300,000. Mortgage. This will depend on your income, job, dependents, credit score, and other factors.

The interest rate, the length of the term and the type of repayment will all be used to calculate your repayments.

The table below shows how the term length and interest rate could affect your monthly payments.

These rates are only for comparison purposes. Talk to a mortgage broker for more exact rates.

What income is required to be eligible?

Lenders will use a multiplier of your income to determine how much money you can borrow. This is done to determine if you are able to afford your repayments and any other expenses. Some lenders will offer loans up to 4.5x your annual income. Others may do 5x and, in certain circumstances, even 6x.

To qualify for a £300k loan, you must earn approximately £67,000 per year. This is based on 4.5x your annual income, £60k if you have 5x income, £50k if 6x income and £50k if you have 50k. Some mortgage lenders will however assess each application individually and make a decision.

Remember that income is very important. However, lenders will consider how much of your salary you spend on other bills. For more information, please see our section.


Your affordability will be calculated by mortgage lenders. This is done by assessing your income to debt ratio. Lenders will consider your monthly income, minus any outgoings. Lenders will consider your DTI as a sign that you have more income available to pay for mortgage payments.

These expenses could include:

  • Council tax
  • Utility bills include water, electricity and gas.
  • Broadband and TV Packages
  • Car insurance
  • Credit cards
  • Car financing
  • Childcare costs
  • Contents and Home insurance

Talk to an expert to find out your debt-to-income ratio and the mortgage options you have.

What amount of deposit are you able to put down?

The mortgage deposit required depends on the price of the property and whether or not you are considered high risk.

Most mortgage lenders limit the loan-to-value (the amount of the mortgage relative to the property’s price) to 90%. Some lenders will accept as little as 10%, while others may require you to deposit more if you’re looking at a mortgage for bad credit.

If you have a higher deposit, like 20%, you will be able to access more lenders and get better rates. This is to lower the chance of you defaulting on your mortgage payments.

You can only take out a mortgage for £300,000. This is not your entire property’s value.

A £300,000.00 mortgage could be obtained for a house valued at £315,000 with a deposit of 5% of £15,700. However, a £300k property would require an additional deposit of 5% of £15,000 so you would need a mortgage of £285,000.

How to get a mortgage for a £300k house

It’s not the same as taking out a £300,000 mortgage. You won’t likely need to borrow the entire amount of the property.

You must also consider the deposit requirements. A majority of lenders require a 10% deposit to purchase a residential property. To borrow £270,000 from mortgage lenders, however, you will only need to have £270,000.

You may be able to purchase a home with this amount of equity using a £285,000 mortgage. Some providers will accept a 5% deposit.

How can the length of your term affect your repayments of 300k?

The typical rule of thumb is that the longer the repayment term, the lower it will cost per month but the higher the likelihood of paying back overall. If you take out a £300,000.00 mortgage for 30 years at a rate of 3.92%, then you would pay £1,418 per month and £510k total. A 10-year term would run you £3,026 per month and cost £363k total.

How can other factors affect your chances of success on getting a 300000 mortgage?

Before granting a mortgage, most lenders will review your entire application. Although each lender may favour different factors, most lenders will consider your entire application before deciding whether to lend. They will also look at your income source and your income. You can find more information about these factors in our brief summaries.

Your age

Many lenders have age limits that are set at the time of an application or after the term ends. Some lenders won’t lend money to people over 50. Others set the limit at 85. Other lenders have no age limits as long as you are able to prove that you will repay the loan.

Your expenses

Your total monthly expenses, as discussed in the debt to-ration section will also be taken into consideration when you apply for a mortgage. This will be expressed as a percentage.

Type of property

Mortgage lenders will prefer more conventional properties because they are easier to sell and have fewer structural problems. They may be cautious about houses with thatched roofs and timer frames, high rise flats, ex-local authority housing and flats above sho£.

Your income source(s)

Some mortgage lenders prefer applicants who have full-time employment on PAYE wages. They will typically not offer attractive rates to applicants with income sources that aren’t standard. This includes the self-employed or those who receive benefits. The experts that we work with can access lenders who accept different income types.

Is it possible to get an interest-only £300,000 mortgage?

Yes, you can. You can. An interest-only mortgage will allow you to pay the interest every month up to the end of the term. After that, you will have to repay the capital or the entire loan. This could help you keep the cost down but it is not a good way to repay your loan.

To get an interest-only mortgage you might need to make a bigger deposit, perha£ 25% or 30%. This will offset any potential risks.

Can you get a £300k buy-to-let mortgage?

You can, however, the rules for property buy-to-let properties are different from residential.

You will often be required to have a minimum income and put down a higher deposit, such as 25%. While lenders will accept a lower deposit, such as 15%, there are still requirements.

You would need to have a suitable property and sufficient rental income to cover at least 125% of your monthly mortgage payments (based upon an interest-only repayment type).

What mortgage calculators are available?

You can find a mortgage calculator at the end of this page.

While it is a good idea to calculate your costs before applying for a £300,000.00 mortgage, one of the most unpleasant surprises could be a possible loan rejection, remember that these calculators will not give you an exact cost but only a rough estimate of what you might be eligible for.
