Right to Buy Mortgage: Ex-Council to Homeowner

Right to Buy (RTB) gives council tenants in England the chance to buy their home at a significant discount. For many people, it's the most realistic route to homeownership — the discount can effectively serve as your deposit. But getting a mortgage for a Right to Buy purchase has its own quirks, especially if your credit isn't perfect.

How Right to Buy Works

If you're a secure council tenant in England and have been a public sector tenant for at least 3 years (it doesn't all have to be in your current home), you may qualify.

The Discount

The discount depends on the type of property and how long you've been a tenant:

• Houses: 35% discount after 3 years, rising by 1% per year up to a maximum of 70%
• Flats: 50% discount after 3 years, rising by 2% per year up to a maximum of 70%

Maximum discount amounts are updated annually. For 2025/26, the caps are:

• £102,400 outside London
• £136,400 in London boroughs

So if your council flat is valued at £200,000 and you qualify for the maximum discount, you could buy it for £63,600. That's a substantial saving.

The Discount as Your Deposit

This is the key advantage for mortgage purposes. Many lenders treat the RTB discount as your deposit. If you're buying a £200,000 property with a £100,000 discount, you're effectively borrowing £100,000 against a £200,000 asset — that's a 50% LTV, which is excellent from a lender's perspective.

This means you may not need any cash deposit at all. The discount alone gives you significant equity from day one.

Eligibility

You qualify for Right to Buy if:

• You're a secure tenant of a council (local authority) in England
• You've been a public sector tenant for at least 3 years (includes time with housing associations, armed forces accommodation, and NHS accommodation)
• The property is your only or main home
• You don't have an ongoing possession order against you

You DON'T qualify if:

• You're a housing association tenant (you may qualify for Right to Acquire instead)
• You live in sheltered housing or housing adapted for elderly or disabled people (in some cases)
• Your council has successfully applied for an exemption
• You're subject to a bankruptcy order or have had your RTB suspended

Getting a Right to Buy Mortgage

Which Lenders Offer RTB Mortgages?

Most mainstream lenders offer Right to Buy mortgages:

• Halifax — one of the most active RTB lenders
• Nationwide — accept RTB with competitive rates
• NatWest — have specific RTB products
• Barclays — accept Right to Buy applications
• Leeds Building Society — flexible on RTB

Specialist lenders like Kensington, Pepper Money, and Accord also lend on RTB, which matters if you have adverse credit.

What Lenders Need

• Your RTB offer letter from the council (Section 125 notice)
• Proof of income and affordability (same as any mortgage)
• Credit checks — your credit history will be assessed
• ID and proof of address
• Details of the property, including the valuation

Affordability

Even with the discount, you still need to demonstrate you can afford the monthly mortgage payments. Lenders will assess your income, outgoings, and existing debts. Remember, owning a home comes with costs beyond the mortgage — repairs, maintenance, buildings insurance, and potentially service charges if it's a flat.

Right to Buy with Bad Credit

Having adverse credit doesn't automatically disqualify you from RTB — the right to buy is between you and the council, and credit doesn't affect eligibility. But you still need a mortgage, and that's where credit matters.

What's Possible

• Defaults over 3 years old — several specialist lenders will consider this
• CCJs under £500, satisfied — some lenders will overlook these
• Low credit score — if caused by thin credit history rather than missed payments, some lenders are understanding
• Debt management plans (completed) — possible with specialist lenders

What's Harder

• Active defaults or CCJs — very few lenders will proceed
• Bankruptcy discharged less than 3 years ago — extremely limited options
• IVA still active — almost impossible until it's completed
• Recent missed payments on rent — particularly damaging, as it directly relates to housing costs

The RTB discount works in your favour here. Because the discount gives you significant equity, lenders face less risk even with adverse credit. A borrower with credit issues but 50% equity is less risky than a borrower with perfect credit and 5% equity.

The Application Process

1. Apply to your council — fill in the RTB1 form
2. Council responds within 4 weeks (8 weeks for flats) confirming your right
3. Council sends Section 125 notice — this is the formal offer with the discount and property valuation
4. Get your mortgage in principle — approach lenders or a broker
5. Instruct a solicitor — you need independent legal representation
6. Formal mortgage application — once you have the Section 125 notice
7. Complete the purchase — exchange and complete like any property purchase

The whole process typically takes 3-6 months from initial application, though it can be longer if there are delays from the council.

The Clawback Rule

If you sell your RTB property within 5 years of buying it, you'll have to repay some or all of the discount:

• Sell within year 1: repay 100% of the discount
• Sell within year 2: repay 80%
• Sell within year 3: repay 60%
• Sell within year 4: repay 40%
• Sell within year 5: repay 20%
• After 5 years: nothing to repay

The discount repayment is based on a percentage of the current market value, not the original discount amount. So if property values have risen, you'll repay more.

First Refusal

You must also offer the property back to your former landlord (the council) before selling on the open market, within the first 10 years.

Joint Applications

You can include up to 3 family members who've lived with you for the past 12 months on your RTB application. This can help with mortgage affordability if you're applying jointly, though all applicants will be credit-checked.

Is Right to Buy Right for You?

RTB can be a transformative opportunity, but consider:

• Can you afford the ongoing costs of homeownership?
• Is the property in good condition, or will it need expensive repairs?
• Are you happy to stay in the property for at least 5 years to keep the full discount?
• Have you had the property independently valued to check the council's valuation is fair?
