How We Secured a High-Street Mortgage for a BISF Metal-Framed Property for First Time Buyers

Summary:

Securing a mortgage on a British Iron and Steel Federation (BISF) steel-framed property often pushes buyers toward expensive specialist lenders due to standard high-street rejections. First Select Mortgage Brokers navigated complex lender underwriting parameters to secure a high-street mortgage at a competitive low rate with a minimal deposit for two first-time buyers.

The Goal: A First Step on the Property Ladder

For first-time buyers early in their careers, stepping onto the property ladder is already a major milestone. Our clients found an affordable home that suited their budget perfectly, allowing them to make the leap from renting to homeownership without overstretching their modest salaries.

However, the transaction carried high stakes. With limited savings, they needed a low-deposit mortgage at a competitive high-street interest rate to ensure their monthly outgoings remained manageable.

The Obstacle: The “Impassable Road” of BISF Construction

The property was a British Iron and Steel Federation (BISF) home—a popular form of post-war prefabricated steel-framed construction. Think of property underwriting like a conveyor belt: high-street lenders prefer standard brick-and-mortar homes because they are straightforward to value and resell. When a non-standard construction type like a metal frame comes down the belt, automatic systems often flag it and halt the process.

Most mainstream banks decline BISF properties outright or demand extensive, costly structural surveys alongside higher deposit requirements. Facing these rejections, the buyers feared their only route forward was a specialist lender.

Standard High-Street Path:   [ BISF Metal Frame ] ──> [ Automatic Underwriting Decline ]
Specialist Lender Path:      [ Higher Deposit Required ] + [ Elevated Interest Rates ]

Whilst specialist lenders can often provide excellent solutions to lending challenges, relying on a specialist lender in this situation would mean:

  • Higher Interest Rates: Significantly increasing monthly payments.
  • Larger Deposit Requirements: Forcing the buyers to delay the purchase to save more capital.
  • Added Financial Stress: Straining a modest budget at the very start of their financial journey.

The Engineering: Securing Mainstream Approval

Rather than accepting a high-cost specialist product, First Select restructured the application strategy from the ground up. Non-standard construction approval is not about changing the property; it is about selecting the exact lender whose criteria matrix accepts the specific structural framework.

First Select executed a three-step placement strategy:

  • Granular Criteria Matching: We filtered the entire mortgage market to isolate the select group of high-street banks whose underwriting guidelines explicitly accept BISF properties without imposing penalizing terms.
  • Pre-Application Surveyor Engagement: We engaged directly with panel surveyors prior to submission to ensure the property met the specific structural conditions required by the chosen bank.
  • Income & LTV Optimization: We packaged the clients’ modest income streams alongside a low-deposit structure (90% LTV), presenting a pristine credit profile to offset the non-standard nature of the building.

By carefully matching the physical properties of the building to the precise risk appetite of a mainstream lender, we bypassed the need for expensive secondary market financing.

The Outcome & Key Takeaway

First Select successfully secured a full mortgage offer with a tier-one high-street bank, delivering a outcome that kept the clients’ homeownership dream intact and affordable.

  • Deposit: 10% (90% LTV)
  • Interest Rate: Market-leading high-street fixed rate
  • Turnaround Time: Full offer issued in 12 working days

Key Takeaway for Buyers: A property decline from a high-street bank is rarely a final “no”—it is often simply a sign that your property type does not fit that specific bank’s automated algorithms. Specialist guidance can help you find mainstream rates on non-standard homes.

How to Get a Right to Buy Mortgage on a Zero-Hours Contract.

Summary:

Single mother in Manchester, purchases home under Right to Buy scheme using zero-hours contract income & working benefit income.

By looking beyond rigid, automated underwriting models, First Select Mortgage Brokers helped a hardworking single mother secure a competitive Right to Buy mortgage on a zero-hours contract. By combining variable earned income with state benefits, we turned a seemingly impossible scenario into permanent housing stability and a lasting family legacy.

Think of securing a mortgage like fitting together a complex jigsaw puzzle. If even a single piece appears misshapen, automated systems at high-street banks immediately push the board off the table.

For many hardworking families, this creates a frustrating paradox: you can reliably pay rent month after month, yet traditional algorithms classify you as “not mortgage worthy” when you try to buy the very home you live in.

The Obstacle: An Assembly Line “No”

Our client, a dedicated single mother living in her council home, was presented with a life-changing opportunity: purchase her property under the UK Government’s Right to Buy scheme. Exercising this right would give her children permanent stability and an asset to inherit in the future.

However, her financial layout didn’t fit the standard high-street mould:

  • Income Structure: Employed on a zero-hours contract, supplemented by Child Benefit and Working Tax Credits.
  • Credit Profile: Satisfactory, with a consistent track record of meeting commitments.
  • The Main Barrier: Multiple mortgage brokers had already turned her away, declaring her combination of zero-hours earnings and benefit income ineligible for high-street mortgage lenders.

To a standard automated system, a zero-hours contract looks like shifting sand. Most high-street lenders require a minimum 12-to-24-month unbroken history with a single employer or outright reject variable-hour contracts when state benefits form a significant portion of the total household income. After several rejections, the door to home ownership seemed firmly shut.

| First Select Outcome     | Approved (100% LTV of Discounted Price)    |
+--------------------------+--------------------------------------------+

The Engineering: Manual Underwriting & Manual Logic

When the client reached Claire at First Select Mortgage Brokers, the approach shifted from automated box-ticking to manual underwriting logic.

  1. Evidencing Income Stability: Claire audited 12 months of payslips and bank statements to establish a solid, predictable baseline for the zero-hours earnings, demonstrating that the income was consistent despite the contractual structure.
  2. Structuring Benefit Alignment: Not all lenders treat state support equally. Claire identified a specialist lender whose criteria fully accepts Child Benefit and Working Tax Credits at 100% value alongside earned income.
  3. Leveraging the Scheme Discount: The built-in Right to Buy discount served as the equity deposit, removing the need for additional cash reserves and mitigating the lender’s loan-to-value (LTV) exposure.

By presenting a fully verified package to a manual underwriting team, Claire demonstrated that the proposed mortgage payments were actually lower than the client’s current monthly rent obligations.

The Outcome: Foundation for the Future

The lender issued a formal offer at a competitive rate, ensuring long-term monthly affordability without stretching the household budget.

Transaction TypeRight to Buy Purchase
Lender TypeSpecialist Manual-Underwritten Lender
Income Assessment100% Averaged Zero-Hours + 100% State Benefits
Core ResultSecured full purchase funding with affordable monthly payments

More than just a financial transaction, securing this mortgage transformed a rental property into a permanent family asset—providing long-term security today and an inheritance for her children tomorrow.

Key Takeaway: A rejection from a computer algorithm is rarely a final answer. If your income structure is non-standard, success relies on matching your specific profile with a lender that uses human judgement rather than automated checklists.

Right to Buy Mortgage
Right to Buy Mortgages Discounts

Right to Buy Mortgages

Right to Buy Mortgages: ‘Right to Buy’ is a government backed home purchase scheme in England for council house tenants to purchase the home they currently rent. The Right to Buy discount is generous and can allow council (and some housing association) tenants to purchase their rental property at a discounted price. Since 1980, thousands of families have used the scheme to purchase their home.

Discounts since 2014:

The maximum discount on any property is capped at £96,000 across England, and £127,900 for properties in London. The amount of discount increases every year in line with the consumer price index (CPI).

HOUSES: You can get a 35% discount for tenants renting for 3 – 5 years. After 5 years, the discount increases by 1% for every additional year up to a maximum of 70% or the above mentioned discount cap.

FLATS: You get a 50% discount for tenants renting for 3 – 5 years. After 5 years, the discount increases by 2% for every additional year up to a maximum of 70% or the above mentioned discount cap.

The maximum discount from April 2024 is £136,400 in London, and £102,400 outside of London.

The above discounts ceased on 21st November 2024. Labour has reduced the amount of discount available. There is a chance these generous discounts may return in the future under a new government, but we should assume they will not change again till around 2019.

If you have have applied for Right to Buy before 21st November 2024, then contact us immediately to so we can arrange your right to buy mortgage. The S125 form which confirms your discount can expire after a certain amount of time. If it expires you will need to reapply under the new lower discounts. So act quickly to arrange your mortgage whilst securing the older more generous discounts.

Discounts from 21st November 2024:

The new maximum discount you can get is the lower of:

  • 70% of the value of the property
  • The maximum discount Cap for your area

Check below to see what region your home is located and the maximum discount Cap for your region. There are also some exceptions that increase or decrease the discount.

REGIONMAX. DISCOUNTEXCEPTIONS
North East£22,000n/a
North West£26,000n/a
Yorkshire & Humber£24,000n/a
East Midlands£24,000n/a
West Midlands£26,000n/a
Eastern£34,000£16,000 in the district of Watford
South East£38,000£16,000 in the areas of Reading Borough and West Berkshire, Hart District, Oxford and Vale of the White Horse District, the boroughs of Tonbridge and Malling, Epsom and Ewell, and Reigate and Banstead 
South West£30,000n/a
London£16,000£38,000 in the boroughs of Barking and Dagenham and Havering

Also worth noting that your discount can be reduced if your Landlord has incurred expenses in maintenance and upkeep of your property. This often impacts flats more than houses, due to communal areas, hall ways and lifts and fire systems that need to be maintained.

What do these changes mean?

In summary it will be harder to purchase your home using Right to Buy, but not impossible!

Because the discount is reduced, many people will need bigger mortgages, which may not be affordable. They may also need to put down a larger cash deposit to buy their home, and they may not have the savings to do so.

However, the discount is still reasonable and effectively ‘free money’ off the cost of your home. The discount can be used as your deposit, so it reduces the amount you need to put in.

For a full breakdown of discounts can be found here: Right to Buy Discounts

Do I need to save for a deposit?

In some cases you do NOT need to save for a deposit. Many mortgage lenders will use your discount as your deposit, this means you do not need to save for a deposit. However this does depend on the value of your home, and for higher value homes, you may need to put some cash in to meet the minimum deposit

Not every lender will offer Right to Buy Mortgages, so speak to us, as an independent broker, we have access to a wide selection of lenders.

Applying for Right to Buy

To start the process of buying your rental property you need to complete the RTB1 form, you can find a link to this form at the bottom of this page. Once this is completed and submitted, your landlord will contact you to confirm you have the Right to Buy.

Your landlord or housing association will carry out a valuation of your home to confirm its value. They will then calculate the discount you qualify for. The discounted purchase price is the price you pay. Your landlord will provide you with an S125 form, which will confirm all the above.

Now is the time to speak to a mortgage adviser, and here at First Select Mortgage Brokers, we have access to the widest selection of mortgage lenders who offer Right to Buy mortgages. We will need a copy of your S125 form to confirm you have the right to buy and your mortgage lender will also need to see this.
