Right to Buy mortgages (for council tenants)

A Right to Buy mortgage is a residential mortgage used to buy a home through the UK Right to Buy scheme. For council tenants, the key feature is that the purchase price is reduced by the Right to Buy discount.

Because the discount changes the purchase price, it can also change the mortgage calculations lenders rely on—such as the loan-to-value (LTV), the deposit position, and the overall funding picture.

This guide explains the main moving parts so you can understand how the scheme and the mortgage process fit together.

How the Right to Buy scheme affects your mortgage

Right to Buy is aimed at tenants in public sector housing (for example, council homes, and in some circumstances certain housing association arrangements).

When you buy under the scheme, the discount reduces the starting point for the purchase price. In mortgage terms, that can mean:

• the mortgage is calculated using a discounted purchase price
• your LTV may be different from what you’d expect if you priced the home at its full market value
• your deposit requirements can vary depending on the final purchase price and the lender’s approach

Even though it’s still a mortgage, it can help to think of the process as two layers:

1. scheme rules determine the discounted purchase price and the mechanics of the sale
2. mortgage underwriting assesses affordability, credit, valuation, and lender-specific requirements

Right to Buy discount basics (and why it matters for LTV)

In England, the Right to Buy discount is generally influenced by how long you’ve been a tenant and can differ depending on whether you’re buying a house or a flat.

The discount is also subject to scheme rules and caps (including different caps for London). Because the discount outcome depends on your circumstances and the property, it’s important that the figures used in the mortgage application are accurate.

Why the discount can change your mortgage figures

The discount can influence:

• how much you need to borrow
• whether the lender is comfortable with the resulting LTV
• how the lender views the overall balance between mortgage, deposit, and any eligible funding

Minimum occupation time before you can buy

Right to Buy purchases typically require a minimum period of occupation before you can proceed.

The minimum can vary depending on the property type and the scheme rules that apply to your situation. Planning around timing can help you avoid delays when you arrange mortgage funding.

Can you get a mortgage for a Right to Buy purchase?

Yes. A Right to Buy purchase can be funded with a mortgage, and lenders will still carry out the usual checks.

In practice, this often means:

• the discounted purchase price is used in the mortgage calculations
• you may not need a separate deposit in every case, depending on the final purchase price and lender requirements
• you still need to meet the lender’s affordability and credit requirements

Some buyers also consider borrowing for eligible costs (for example, certain home improvements). How this fits into the mortgage depends on the lender’s approach and the overall application.

What lenders typically assess for Right to Buy mortgages

Even with a discounted purchase price, lenders focus on whether the mortgage is affordable, sustainable, and properly underwritten.

Common areas of assessment include:

1) Affordability

Lenders review your household income and regular outgoings to determine whether repayments fit their affordability framework.

2) Existing debts and commitments

Current loans, credit arrangements and other monthly commitments can reduce the amount of disposable income available.

3) Credit history

Your credit record is assessed for evidence of past repayment behaviour and current financial management.

4) Mortgage term and repayment type

The length of the mortgage term affects monthly payments and whether the lender’s internal limits are met.

5) The property and valuation

A valuation is typically required. Lenders want confidence that the mortgage is supported by the property’s value and the agreed purchase details.

6) The Right to Buy figures used in the application

Because the discount changes the purchase price, lenders will want the correct information about the discounted price and how it affects the overall funding.

Joint purchases and how affordability is assessed

Right to Buy can sometimes be used for joint purchases, such as buying with a spouse, civil partner, or another eligible person.

From a mortgage perspective, joint buying generally means the lender assesses combined affordability. That typically involves reviewing each applicant’s:

• income
• outgoings
• debts and commitments
• credit history

Costs to plan for when buying through Right to Buy

A Right to Buy discount reduces the purchase price, but buying still involves costs.

Potential costs can include:

• legal fees
• valuation/survey costs
• mortgage-related fees (where applicable)
• stamp duty (depending on the final purchase price and your circumstances)
• insurance and protection (often including buildings cover)
• ongoing maintenance and repairs after completion

Budgeting for these items early can help you avoid surprises once the purchase is underway.

Selling restrictions after buying under Right to Buy

Buying through Right to Buy can come with restrictions on selling.

These restrictions can include requirements to repay part (or all) of the discount if you sell within a certain period, and in some situations you may need to offer the property to your former landlord or another social housing provider before marketing it on the open market.

Understanding these rules early helps you plan for the long term—particularly if you think your circumstances might change.

How specialist mortgage support can help

Right to Buy involves two layers of process:

1. the scheme rules (discount, eligibility, timing, and purchase mechanics)
2. mortgage underwriting (affordability, credit, valuation, and lender-specific requirements)

Because the discount affects the purchase price and LTV, having a clear view of how the Right to Buy figures translate into a mortgage application can reduce the risk of avoidable delays and help you prepare the right information from the start.

Key takeaways

• A Right to Buy mortgage funds a purchase made under the Right to Buy scheme.
• The discount reduces the purchase price, which can affect your mortgage amount and LTV.
• You still need to meet affordability and credit requirements like any other mortgage.
• Tenancy length and property type influence the discount, and minimum occupation periods can affect timing.
• Joint purchases may be possible, with lenders assessing combined affordability.
• There can be selling restrictions after purchase, including potential discount repayment.

Understanding how the Right to Buy discount interacts with mortgage underwriting can make the path to ownership clearer and help you plan with confidence.
