Mortgage Guarantees for Help to Buy Applicants

Mortgage guarantees can be a lifeline for applicants who don't quite meet eligibility criteria or minimum deposit requirements. Discover how a mortgage guarantee could transform your mortgage offers as a Help to Buy applicant.

About your mortgage

Error: Yearly income income must be between £1 and £10,000,000.

Error: Regular bonus must be between £1 and £10,000,000.

Based on your yearly income, you may be able to borrow:


Most lenders will let you borrow 4.5 times your annual salary so, as long as you have a standard 10% deposit, you should be able to borrow this much.


Depending on your personal circumstances, some lenders may let you borrow 5 times your salary.


Lenders usually cap the amount they lend at 5.5 times your salary, so it’s unlikely you’ll be able to borrow more than this.

This calculator is an estimation of how much you could borrow. If you’re ready to take out a mortgage, speak to a Revolution brokers to see what options are available.

Mortgage Guarantees for Help to Buy Applicants

Deposit requirements are often one of the biggest obstacles to getting onto the property ladder; and the Help to Buy scheme does provide assistance, although you'll need a 5% deposit to qualify.

Here we'll run through different options to help you buy a property with a low deposit or no deposit at all - including Help to Buy and the alternatives.

How Can a Help to Buy Mortgage Help?

Help to Buy is a government-backed initiative, which aims to support homebuyers who are struggling to raise a deposit, or to find competitive mortgage lending.

There used to be a Help to Buy mortgage guarantee scheme, which made it easier to find approval as a first-time buyer or home mover. Like Help to Buy, the mortgage guarantee initiative required a 5% applicant deposit and topped that up by up to 15%.

This scheme has been discontinued, but there are a few different alternatives available.

  • Help to Buy Equity Loans

The Help to Buy equity loan requires the same 5% deposit, and you can borrow up to 20% of the property value or 40% in London.

You'll need a mortgage for the 75% balance - or 55% in London - and don't need to pay interest for the first five years. After five years, interest becomes chargeable at 1.75%, increasing each year by the Retail Price Index plus 1%.

  • Lifetime ISAs

A lifetime ISA, or LISA, is a good alternative to the now discontinued Help to Buy ISA. You can use this option if you are over 18, below 39, and a first-time buyer. The ISA works like a regular savings scheme, but with a limit of £4,000 per annum. For every amount you save, the government adds 25%.

As your savings grow by 25%, you can make up a deposit value faster. If you have used the scheme for over a year, you can use them as a deposit on any first-time buyer property up to £450,000 in value.

  • Help to Buy Shared Ownership

Another Help to Buy option is to consider the Shared Ownership scheme - aimed at helping first-time buyers or those on low incomes buy a proportion of a property. Low income is classified as a household with a maximum income of £60,000 per year.

You can buy anywhere from 25% to 75% of a new-build, or a resale property, and pay a small amount of rent on the balance you do not own. You can also buy out the shares to earn more, or all, of the same property.

  • Bank Purchase Assistance Schemes

As well as government schemes, you'll also find private initiatives and bank support programmes, usually for first-time buyers only. Examples include:

  • Barclays - Family Springboard
  • Lloyds TSB - Lend a Hand

This sort of scheme means that family members can contribute. There is usually a minimum contribution from the buyer and a limit of a 10% contribution from family members towards the property purchase price.

Generally, that cash is not used as a deposit, but the money is held in a savings account and paid back after three to five years with any interest accrued.

What are the Affordability Criteria for a Help to Buy Mortgage?

Whichever lender you apply to, they will need to look at how much you earn, and be confident that you are financially stable and will be able to keep up with your mortgage repayments.

In most cases, this calculation is capped at three or four times your annual income, which is the maximum a lender can offer.

Specialist lenders can sometimes offer up to five or even six times your annual income, although this depends on your circumstances, and is higher than you'd be able to borrow through the Help to Buy scheme.

Which Other Factors Affect My Ability to Get a Help to Buy Mortgage?

These are some of the typical eligibility criteria that can make it challenging to find an affordable Help to Buy Mortgage:

  • Having a low credit score. If you have a bad credit history, you might find it harder to secure lending. This will depend on how severe your bad credit issues were, and when they occurred - and the lending policies of the lender.
  • Your age is also a consideration - some lenders set a higher age cap. However, other lenders have no maximum age, and will happily lend to retired applicants provided you have a stable income.
  • The property type is also a factor - and if you're looking to buy a rental property, you will not be eligible for Help to Buy. Likewise, any unusual property considered non-standard requires a specialist lender.

How much the property is worth is also considered - the below restrictions apply:

  • You can use a Help to Buy equity loan to purchase a property at a maximum £600,000 value.
  • LISAs are available for purchases up to £450,000 sale price.

Which Mortgage Lenders Offer Help to Buy Products?

With various schemes available to help you get onto the property ladder, it is essential to apply to the right lenders, who are aligned with the scheme you are interested in and will be in a position to accept your application.

Many high street lenders offer products to help boost your deposit value but might charge higher interest rates than you will find through off-market products available only through accredited brokers.

The best way to find Help to Buy lending or an alternative scheme that will be more beneficial is to work with an independent broker who can recommend any product from any lender that we think is best suited to you.
