However, it comes with ongoing costs beyond the mortgage that are important to consider – such as rent on the non-owned portion and service charges.

Britons are urged to crunch the numbers to ensure its competitive compared to privately renting in their target area.

Gray said: “The first thing to watch out for is the rent payment you’ll be forking out every month on top of your mortgage.

“With shared ownership, you only purchase a share of the property initially – let’s say 25 per cent or 50 per cent.

“For the remaining portion owned by the housing association, you’re paying rent. And we’re not talking peanuts here.

“On a £200,000 home where you own just 25 per cent, that rent could easily set you back £500-£750 per month.”

Service charges are another hidden cost people must be aware of, and these may be charged if the property is part of a larger development with shared amenities like gardens, hallways, or lifts that need maintenance.

Homeowners may have to part with an extra £20 to £40 per month, which is another outgoing to stay on top of, Gray said.

In terms of value, shared ownership buyers can benefit from equity growth if property prices rise, and staircase purchases over time could ultimately get one to full ownership.

However, there may be restrictions on things like sub-letting or flexibility if one’s lifestyle changes at a later date, such as they need to move away.

Staircasing also becomes increasingly expensive as costs increase the higher the share is.

However, Gray explained that with staircasing, people need to be aware that there are valuation fees and assorted costs often running into hundreds of pounds.

“You’re having to repeatedly fork out just to buy a bigger slice of a place that’s already yours,” he said.

“But what I always stress to any of my clients considering this route is to go in with open eyes on all the extra unavoidable expenses, both monthly and down the line.

“On paper, that mortgage payment might look nice and affordable. But once you factor in rent, service charges, and fees to staircase or sell further down the road, that ‘affordable’ price tag doesn’t look so friendly after all.”

As someone’s financial situation strengthens, they may consider moving towards full ownership via ‘staircasing’. However, they should ensure this is right for them.

Gray recalled working with a client who had bought a 40 per cent share of a charming semi-detached house through shared ownership.

Although the house was in good condition and in a good area, they soon found selling on these property schemes can be difficult.
