A booster is a helper.
Most first-time buyers need help getting on the property ladder.
Some struggle to pull together a deposit.
Some struggle to borrow enough on their income.
Some struggle with deposit and income.
That's where boosters can help.
A deposit booster helps with the deposit in return for a financial interest in the home.
An income booster goes on the mortgage (not the property deeds), adding their income to boost affordability.
One person can choose to be both an income booster, as well as a deposit booster.
