Buying with us

Catalyst have been at the forefront of housing for more than 80 years and more than 31,000 modern homes in London and the South East, through a wide range of rental and home-ownership opportunities.

We are one of the leading housing associations in London and the South East and aim to be a catalyst for change and improvement wherever we work, pursuing better homes, better service and a better future for our customers.

Help to Buy: Equity Loan

With a Help to Buy: Equity Loan the Government lends you up to 40% of the cost of your newly built home, so you’ll only need a 5% cash deposit and a 55% mortgage to make up the rest. You won’t be charged loan fees on the 40% loan for the first five years of owning your home.

Equity loans are available to first time buyers as well as homeowners looking to move. The home you want to buy must be newly built with a price tag of up to £600,000. You won’t be able to sublet this home or enter a part exchange deal on your old home. You must not own any other property at the time you buy your new home with a Help to Buy: Equity Loan.

Shared Ownership

Shared Ownership* makes buying a home more affordable, allowing you to purchase a share of between 25–75% of your new home and pay a below–market rent on the remaining share.

When the time is right for you, you’ll be able to purchase additional shares (known as staircasing) all the way up to 100%. Please contact our sales team for more details.

Market Sale

If you are able to purchase a property without any Government assistant we have a fantastic selection of properties available on the open market.
