Homebuyers are trying to get on the property ladder or move up to the next rung.

If you're struggling to make your next step or homeownership seems like a distant dream, you're in the right place.

Why use a deposit boost?

Own your dream home faster

Saving a house deposit takes an average of 8 years. But with a little help from your loved ones, you can reduce this to just a few weeks. That’s an extra 8 years to build up a nest egg, paying off your own mortgage each month instead of someone else’s. And with house prices showing no signs of slowing, you could be building healthy equity, too.

Protect as much of your money as possible

Most first-time buyer or low-deposit buyer mortgages have one thing in common. They’re pricey, and they're getting more expensive by the day. By boosting your deposit, we could unlock the best mortgage deals on the market; saving you tens of thousands of pounds. More money for you, less for the banks & landlords.

Don't compromise

Most lenders will let you borrow 4.5x your combined income. Some lenders do more, some do less, but with the average house price coming in at 7.5x income, there's still a huge affordability gap. Whether it's a garden or a spare bedroom, we'll increase your affordability so you don't need to compromise on what's important to you.

How does a deposit boost actually work?

We'll unlock money from your homebooster's existing property, then use that cash to either top up your deposit or create one from scratch.

Nuts & Bolts

When you speak to your homebooster, these are the key features of the deposit boost to explain to them.


A deposit boost is an interest-only mortgage taken out against your homebooster’s property, which unlocks money for your house deposit. In mortgage land, this product is called a retirement interest only mortgage (RIO).


The interest is payable monthly by the homebooster, although many of our homebuyers opt to cover these fees. Terms are flexible, but most often the balance itself isn't due until the homebooster moves, if they go into care or die.

Expert advice

A dedicated mortgage expert will arrange the deposit boost and the first-time or second-time buyer mortgage for your family. We'll be right by your side throughout to ensure things go smoothly.

Low rates

Interest rates for the booster mortgage are typically between 2%-3%, although your broker will confirm a live rate.
