The IFIsa aims to raise £367,500 and will offer a return of up to 6.5% to investors.

Initial funds from the IFIsa will be used to renovate and develop a property in south-west London, which will help house residents with learning disabilities and those that require 24/7 care.

JustUs will provide a bridging loan to Mersten for up to 50% of the property’s value to fund the renovation.

Mersten provides an integrated and human approach to property development and develops bespoke homes for vulnerable people.

Lee Birkett, founder and chief executive at JustUs (pictured above), said that it was delighted to be working alongside Mersten to offer this unique investment opportunity.

“It will make a real difference to those people who require bespoke homes and 24-hour care.

“This project is an extremely attractive proposition for those savers who are looking for ethical projects where their money can work for them and others.

“Our aim is to fund 100 properties over the next two years, so it's extremely exciting to launch the first of these projects."

The IFIsa will return monthly interest to investors and has no fees attached, with all loans covered by a first legal charge secured on the properties.
