Increase the size of your house deposit with help from your family

What is a Deposit Boost?

A Deposit Boost is a safe & ethical way to unlock money from a family member or friend’s property to top up an existing house deposit or create one from scratch.

Let’s see if you’re eligible for a Deposit Boost

What are you looking to do?

Deposit boosters are:

  • Willing to help the buyer

  • A homeowner already

  • Able to get their boost back

Deposit boosters are not:

  • Liable for the buyers’ mortgage

  • Listed on the deeds

How a Deposit Boost works


So let’s say your dream home is £200,000 but you only have a £5,000 deposit



With Tembo and an eligible booster, we could get you that home.



Your Booster wants to help you get to a 15% deposit

But without the cash to hand, they turn to Tembo. Our family mortgage specialists assess the Booster's eligibility and recommend the best way to unlock money from their home with a Deposit Boost.
See the available options.

They release £25,000 from their property and gift it to you

As the Deposit Boost is in their name, the Booster is legally responsible for monthly payments. Any arrangement for the buyer to pay this back to them is a personal agreement between the family.
Find out how much repayments could be.

With your £30,000 deposit, we find you a great mortgage to buy your home

A bigger deposit means lower interest rates, and we compare thousands of products to get you a great deal on your mortgage.

Your Booster has helped you get on the ladder!

Plus, the funds from the Deposit Boost are legally gifted, meaning your Booster could reduce their inheritance tax liability. You could return the £25,000 further down the line depending on your circumstances

Neither Tembo nor PRIMIS is able to provide taxation advice. Should you require advice on taxation matters, you should consult with a suitably qualified professional.

Time to enjoy your home!

  • Repaid at the end of term

Retirement Interest-only Repayment

  • For Boosters over 55
  • Lower monthly payments as the Booster only pays interest each month
  • Rates typically 2.5%-3.99%
  • Typically there is no end term, but Boosters can repay the loan after a fixed period if preferable

Standard Remortgage Repayment

  • For Boosters with good income, usually under 55
  • Choose between capital or interest-only monthly repayments depending on your preference
  • Rates typically 1.5%-2.99%
  • Repaid at the end of term (usually when the Booster is 75-80)

Tembo can get first time buyers on the ladder instantly.

The bigger the deposit, the lower the interest fees.

An alternative way to access the funds you need.

Monthly payments start from as little as £22 to access £10,000. Plus, our mortgage brokers will run affordability checks for the Booster to be sure the Deposit Boost is suitable.

Keep in mind...

There will be debt against the Booster's home

  • As with any mortgage, there is a risk of repossession if monthly payments are not paid. Our team of mortgage brokers will assess the affordability of the Booster through our stringent affordability checks to try and mitigate the risk of this happening.

The Booster needs to evidence affordability

  • As the Deposit Boost is a mortgage product, Boosters will need to pass a credit check and prove affordability when applying. If the Booster is overcommitted with existing borrowing and outgoings, or their income isn't sufficient, they may not be eligible for a Deposit Boost.

Eligibility depends on the Booster's existing mortgage

  • Unlike Income Boosts, to be eligible for a Deposit Boost, your Booster will need to have either paid off their mortgage or have paid off the majority of their mortgage in order to be able to unlock additional funds.
