Using the Right

Using the Right to Buy discount as a deposit, how it works, and the common reasons lenders say no

The Right to Buy discount can sometimes be used instead of a cash deposit, but it isn’t automatic. Lenders treat the discount as equity, not savings, and will still assess affordability, credit history, property type, and risk. Most Right to Buy declines happen because the case is placed with the wrong lender or key details are misunderstood, not because the scheme itself doesn’t work.

How it works, and the real reasons lenders say no

If you’re buying your council home under the Right to Buy scheme, you’ll hear this phrase a lot:

“Your discount can be used as your deposit.”

Sometimes that’s true.
Sometimes it absolutely isn’t.

This is where most confusion starts. Tenants get told different things by councils, banks, comparison sites, and even brokers. One lender says yes, another says no, and no one explains why.

This guide breaks down how the Right to Buy discount works as a deposit in practice, when lenders accept it, and the most common reasons applications get declined, even when the numbers look good.

Can the Right to Buy discount be used as a deposit?

Yes, in many cases the Right to Buy discount can be used instead of a cash deposit.

But lenders don’t see it as a “deposit” in the normal sense.

They see it as equity.

Here’s the difference:

  • The property has a market value
  • You buy it at a discounted purchase price
  • The difference between the two is treated as equity
  • That equity reduces the loan-to-value

Example:

  • Market value: £300,000
  • Right to Buy discount: £100,000
  • Purchase price: £200,000

If a lender is happy with the case, they may lend the full £200,000 with no cash deposit, because the equity already exists on day one.

That’s the theory.

Now let’s talk about reality.

Why lenders often say no, even when the discount looks big enough

This is the part most blogs skip.

Lenders don’t just look at the maths. They assess risk, and Right to Buy cases have several risk points that can trigger a decline.

Here are the most common ones we see.

1. The discount is too high for the lender’s comfort

Some lenders cap how much discount they’re willing to accept as equity.

If the discount is very large compared to the purchase price, the lender may worry about:

  • Resale risk
  • Negative equity if prices fall
  • Restrictions during the discount repayment period

This is lender-specific. One bank may be fine, another may decline instantly.

2. The property type doesn’t fit standard criteria

Certain council properties are harder to mortgage, even with a discount.

Common problem types include:

  • High-rise flats
  • Non-standard construction
  • Properties above commercial premises
  • Short remaining lease lengths

The discount doesn’t override these issues. The property still has to be mortgageable.

3. Credit history issues

Right to Buy lenders are often less forgiving than people expect.

Even with strong equity, lenders can decline if there are:

  • Recent missed payments
  • Defaults or arrangements
  • Unstable credit conduct in the last 12 to 24 months

Equity helps, but it doesn’t cancel out affordability or credit risk.

4. Affordability doesn’t pass stress testing

This catches a lot of people out.

Even with no deposit, you still need to afford the mortgage under the lender’s stress rate.

Rising rates mean some Right to Buy cases fail affordability, especially where:

  • Income is variable
  • Overtime or bonuses aren’t accepted
  • Existing credit commitments are high

The discount does not improve affordability calculations.

5. Tenancy history issues

Most lenders want to see:

  • A clear Right to Buy notice
  • A stable tenancy history
  • No unresolved rent arrears issues

Any gaps, disputes, or recent changes can delay or derail an application.

“No deposit” does not mean “no money at all”.

You’ll still need funds for:

  • Solicitor fees
  • Mortgage fees
  • Valuation costs
  • Repairs the council won’t fix

Some lenders will also want to see evidence of savings, even if they’re not being used as a deposit.

Why different banks give different answers

This is where most buyers lose confidence.

One bank says yes. Another says no. A third won’t even look at it.

That’s because Right to Buy cases are not assessed consistently across the market.

Some lenders:

  • Treat the discount fully as equity
  • Allow 100% of the purchase price to be borrowed

Others:

  • Limit loan-to-value regardless of discount
  • Require a small cash contribution
  • Apply stricter property rules

This is why lender choice matters far more than headline claims about “no deposit mortgages”.

Real example from MBNM

A client came to us living in a council property, never expecting to own it.

  • Market value: £300,000
  • Right to Buy discount: £100,000
  • Savings: £0

They’d been told by others it wasn’t possible.

We structured the case correctly, selected a lender that accepted the discount as equity, and raised the full £200,000 purchase price with no cash deposit.

The difference wasn’t the scheme.
It was how the case was presented and where it was placed.

When using the discount works best

Right to Buy discount cases tend to succeed when:

  • Credit history is clean or improving
  • Income is stable and provable
  • The property is standard construction
  • The lender is chosen for the specific risk profile

When those line up, the discount can work exactly as people hope.

How Mortgage Brokers Near Me help

At Mortgage Brokers Near Me, we don’t treat Right to Buy as a generic product.

We look at:

  • Whether the discount will actually be accepted
  • Which lenders are realistic before any application
  • How to avoid wasted credit checks
  • What needs fixing before you apply, not after

That’s how we prevent avoidable declines and keep expectations grounded in reality.

Final thoughts

The Right to Buy discount can act as your deposit.

But it isn’t automatic, guaranteed, or universal.

When lenders say no, it’s rarely because the scheme doesn’t work. It’s because something in the case doesn’t fit that lender’s rules.

Understanding that difference is what turns confusion into a mortgage offer.
