We are often approached by people worried if they can get a mortgage on a steel-framed property.  Many have been declined for a mortgage or will be looking to get a mortgage with bad credit.

In this article, we’ll discuss steel framed houses and provide some advice about getting a mortgage for one. If you’re looking to buy a steel-framed house, the expert advisors we work with may be able to help you.

Can I get a mortgage on a steel framed house?

Yes. It’s possible, though it will depend upon the type of steel framed house in question.

Due to problems with resale and insurance, some lenders won’t even consider steel frame house mortgages. Others will consider more ‘reliable’ kinds of steel frame construction. Others will lend on the majority of such houses.

As with many mortgage-related challenges, it’s all a matter of finding the right lender.

That said, before trying to get a mortgage on a steel frame property, you’ll want to find out exactly what kind of construction it’s made from. This can be ascertained by getting a detailed survey done first.

Not all steel framed houses are the same

There’s a lot of variety in build quality in the steel frame category. For example, the ’Wimpey No-Fines’ design has shown to be more reliable than a lot of other steel framed designs.

Unfortunately, the Wimpy style only accounts for a small part of the steel frame house market – and most of the alternatives haven’t proven to be as structurally sound.

Some steel framed properties can be reinforced

Some steel framed houses can be toughened (a process that often involves reinforcing the foundations with brick). This can result in a property that is more structurally sound (and more mortgageable) – but it can be an expensive process.

It might be harder to get insurance on a steel frame house

Due to the uncertainty around their reliability, getting insurance for a steel framed house can be difficult.

There are a few specialist lenders who operate in this space, though you might be looking at premiums that are higher than normal.

We're so proud of our customers

See how our customers managed to borrow more after they were matched with a specialist broker.

Southport, UK
I was stung by a property survey that found steel framework in the house I was buying so they pulled the plug on my mortgage. My first instinct was to turn to Google for advice and Online Mortgage Advisor was one of the first sites I tried. I contacted them, it wasn’t long before they connected me to a friendly mortgage broker and they matched me to a lender who had no issued with steel frame properties.
Lancashire, UK
As a single dad I needed to borrow 5 times my salary to afford the property I wanted. Every lender I met with capped their borrowing at 4.5 times salary and refused me even though I had great credit. Online Mortgage Advisor recommended a building society who I'd not considered, but borrowed up to 5.5 times salary! Suddenly my application was accepted and me and my daughter were one step closer to our new home.

What deposit is needed for steel frame home mortgages?

Due to the perceived risks involved with steel framed properties, you are very likely to need a larger deposit – even with impeccable credit and high income, they may charge you a higher rate of interest to balance what they see as the risk of lending on a non-standard property, such as a steel frame building.

Most residential mortgage lenders ask for a minimum deposit of 10%, so there is a chance you will need more than that if the property you’re buying has a steel frame. How much more may depend on the results of the results of the property surveys and your creditworthiness.

What about BISF construction mortgages?

BISF (British Iron and Steel Federation) homes make up a large proportion of the steel frame market.

Unfortunately, BISF houses are known to be one of the more structurally problematic varieties of steel framed property.

Can I get a British Iron and Steel Federation house mortgage?

As such, approaching a lender for a British Iron and Steel Federation house mortgage might be a tough ask.

Like many other steel frame properties, BISF properties can also be reinforced with brick – this is expensive, but can increase the odds of getting a mortgage on one.

As with most things mortgage-related, there are specialist lenders who better understand this market, and may be more willing to lend. The experts we work with may be able to find them for you.

What are ‘steel frame’ properties?

‘Steel frame’ is a relatively rare form of house construction that became very popular for a period after World War Two. As you may imagine, ‘steel frame’ is a kind of construction in which the frame of the house is made of steel, which contrasts with other house frames – which can be made of timber.

Many of these properties were built decades ago to house people displaced after the war. A large number of them were intended to be built on a temporary basis, and were never meant to be used up to today.

As such, lenders deem these properties as ‘non-standard’. Because of this, mortgages on steel framed properties can be difficult to get – but not impossible.

Should I be concerned about resale if I have a steel framed property mortgage?

Typically, it is harder to sell a steel framed house due to the problems around insurance and mortgageability outlined above. This is worth bearing in mind if you’d be looking to sell it quickly in the future.

Can I get a mortgage on a steel frame building if I have bad credit?

Bad credit tends to restrict the number of lenders who are willing to work with you, this can be more troublesome in what is already a smaller market, like steel framed properties but there could be bad credit mortgage lenders available

What is the problem with steel frame homes?

The main issue is around build qualify as many types of steel framework can develop structural issues. This means that steel frame properties can be more difficult to sell and insure, and are therefore mortgage difficult to get a mortgage on.
