How to Sell a Help to Buy Property
Selling a property with a Help to Buy equity loan has a specific process that involves several unique administrative and valuation steps that a standard house sale does not. Because the government holds a percentage-based financial stake in your home, you cannot simply agree on a price with a buyer and move on; you must repay the outstanding equity loan in full upon completion of the sale.
In this article, we'll examine the additional steps in the conveyancing process, and guide you through the frequently asked questions, such as, Can I sell it for more than the valuation?
The Golden Rule: RICS Valuation vs. Sale Price
The most critical financial concept to understand when selling your Help to Buy home is how Homes England calculates the exact cash amount you owe them. Because your loan is a percentage of your property's value (usually 20% or 40% in London), rather than a fixed cash sum, the repayment figure fluctuates with the property market.
To establish the current market value, you must instruct an independent RICS surveyor. However, Homes England enforces a strict Golden Rule when calculating their final cut: they will calculate your repayment based on the RICS valuation or the actual agreed sale price, whichever figure is higher.
Example: How the higher figure impacts your repayment
Imagine you originally took out a 20% Help to Buy equity loan. When you decide to sell, the calculations work as follows, depending on your estate agent's performance:
- If your property sells for MORE than the valuation: Your RICS surveyor values your home at £250,000, but an estate agent secures a buyer who agrees to pay £260,000. Homes England will ignore the £250,000 valuation and calculate its 20% share based on the £260,000 sale price. You will owe them £52,000.
- If your property sells for EXACTLY the valuation: Your RICS surveyor values your home at £250,000, and you accept an offer from a buyer for £250,000. Homes England calculates their 20% share from this matching figure. You will owe them £50,000.
Because of this rule, you cannot use a low RICS valuation to artificially reduce the amount you owe the government if the open market is willing to pay more for your home.
What if I sell for less than the RICS valuation?
Property markets fluctuate, and you may find yourself in a position where the highest offer you receive from a buyer is lower than the figure provided by your RICS surveyor. If you accept an offer for £240,000 on a home valued at £250,000, the Golden Rule still applies: Homes England will insist on calculating their 20% share based on the higher £250,000 valuation (£50,000).
This creates a shortfall. Since the sale proceeds from your buyer will only cover a portion of the debt, you will be legally obligated to make up the difference out of your own pocket or from your remaining equity upon completion.
If you cannot afford to cover the shortfall, your conveyancing solicitor must apply to the Help to Buy Administrator for special permission to conduct a "Sale Under Value". Homes England will require extensive evidence from your estate agent proving that the property was marketed correctly and that the lower offer represents the true market value before they will consider releasing their legal charge.
Expert Tip: The Five-Year Myth:
A common misconception among homeowners is that you are locked into the property for the first five interest-free years. In reality, you are legally entitled to sell your Help to Buy home on the open market at any point. The equity loan is simply settled using the equity and sale proceeds once the transaction completes.
The only 5-year rule that applies to Help to Buy equity loans relates to when you exit the rent-free period and start paying interest on the loan on a monthly basis.

What is the process for selling a Help to Buy property?
You can sell a Help to Buy property on the open market like any other property. However, because you have an outstanding equity loan, the process differs from that of a standard sale. The loan must be repaid in full from the proceeds of the sale, and Homes England must approve the transaction. Here is a detailed, step-by-step guide to the Help to Buy selling process:
Help to Buy Valuation
The first stage is to obtain a Homes England-compliant RICS surveyor to value your property. The valuation is used to calculate the repayment amount of your equity loan.
The report is only valid for three months, and you must send it to Homes England within five working days of its issue.
Expert Tip: Valuation extensions or repeat valuations are almost unavoidable
Because you need the Help to Buy valuation to set the sale price and the valuation only lasts for 3 months, you can be caught waiting for an offer from a buyer as your valuation slowly expires. Help to Buy allows you to extend your report, but you must act quickly to avoid paying for a brand-new physical survey.
- 1-month extension: Your original RICS surveyor can provide a formal extension letter. The cost for this is normally free, or less than £100 INC VAT.
- 3-month extension: Your original surveyor can complete a desktop valuation within two weeks of the expiry date, providing comparable property sales to justify any price changes. The cost for this is normally around half of the price you paid for the site-visit valuation.
Crucially, whichever extension you use must be supplied to Homes England as an uneditable PDF within 5 days of being issued. If your transaction still does not complete within this extended period, you will be forced to start again and pay for a completely new physical valuation.

Instruct a Help to Buy Solicitor
You'll need a specialist solicitor who is qualified to handle the nuances and deadlines of the Help to Buy repayment process. They handle the redemption receipt, request the authority to complete it, and pay off the loan.
Administration Fees and Application Form
You complete your Application Form and pay your £200 administration fee once you have found a buyer and not before. Homes England will need to have evidence that you have accepted an offer via the Memorandum of Sale created by the selling estate agent. If you haven't found a buyer yet, you may still be able to obtain an indicative redemption quote if you have a market appraisal from your estate agent.

Redemption Letter
Once Homes England has approved your valuation and application, they will send a redemption letter to your solicitor. This letter confirms the exact amount you owe, including any accrued interest. It also contains the legal undertaking documents your solicitor needs.
Expert Tip: Homes England doesn't always agree with the valuation
Homes England has strict criteria for the RICS valuation report. If your valuation report does not meet these criteria, or if Homes England considers the valuation too high or low compared to similar properties, they will reject it. Here are the specific reasons Homes England may reject a valuation:
- The valuer was not qualified: The report must be prepared by a Royal Institution of Chartered Surveyors (RICS) Registered Valuer. For the Help to Buy: Equity Loan (2021-2023) scheme, the surveyor must specifically be an MRICS (Member) or FRICS (Fellow). Estate agent appraisals or automated online valuations are not accepted.
- The valuer was not independent: The surveyor cannot be related to or known to you, and they must be completely independent of any estate agent involved in marketing the property.
- The valuation report has expired: The initial physical valuation report is only valid for 3 months. If it expires before you complete your transaction, you must provide a valid extension (a 1-month letter or a 3-month desktop valuation).
- There were no internal inspections: The original valuation must involve a physical inspection of the inside of the property. Drive-by or desktop valuations are acceptable only if they are formal extensions of a prior physical inspection.
- Comparable evidence was weak or missing: The surveyor must provide at least 3 comparable properties that sold within the last 12 months. These must be similar in type, size, and age, and located within 2 miles of your home. If this evidence is inappropriate (e.g., comparing a flat with a house) or not provided, the report will be rejected.
- Incorrect format or missing information: The report must be supplied as an uneditable digital document (like a PDF), be on the surveying company's headed paper, and be addressed directly to Homes England. It must also include the surveyor's RICS registration details and a statement of their independence.
If your valuation report is rejected, you will have to provide and pay for a new, compliant report.
CEO & Managing Director
Standard Conveyancing Process
Issuing contracts, replying to enquiries, obtaining a mortgage redemption statement, (if applicable) the leasehold management pack, and getting you to sign the TR1 and contract in readiness for exchange of contracts. This is all part of the normal conveyancing process the solicitor handles as part of a sale.
Legal Undertaking
Your solicitor will provide a legal guarantee to Homes England that the loan will be repaid in full from the sale proceeds on the date of completion.
Authority to Complete
This final document confirms that all the necessary conditions have been met and the sale can proceed. You cannot complete without this. Next, the sale completes, and the equity loan is repaid from the proceeds. Any remaining funds are then transferred to you.
Once the loan is paid, Homes England will apply to the Land Registry to remove the charge on your property.
- MRICS & FRICS-accredited surveyors.
- 100% Homes England-compliant reports.
- Transparent, fixed-fee pricing.
- Rapid desktop extensions.
- Fast availability from 05/08/2026.
How is the Help to Buy loan repayment calculated?
A common misconception is that you repay the fixed amount you originally borrowed from Homes England. However, the loan is an equity share, not a fixed sum.
The amount you repay is a percentage of the current market value of your home when you sell.
This means if your property's value has increased, you will repay more than you originally borrowed. But this is a key point: if your property's value has decreased, you will repay less than you originally borrowed. This also applies if you are selling a Help to Buy property at a loss.
The final repayment amount is based on either:
- The market value of your home, as determined by the RICS valuation, or
- The price you sell the home for, whichever is higher.
An example of repaying with a loss
Let's say you bought a house for £200,000 with a 20% Help to Buy loan (£40,000). If you now sell the property for £180,000, your repayment is calculated from the lower sale price. You would pay back 20% of the new value:
20% of £180,000 = £36,000
In this scenario, you would pay back £4,000 less than the original loan amount, as the loan absorbed a portion of the loss. This is a vital piece of information for anyone worried about selling a house with Help to Buy in a falling market.
Is it better to pay off Help to Buy before selling?
When you sell a Help to Buy property, you will have to repay the equity loan regardless. However, you can choose to repay the loan as a separate transaction before you list the property.
- The sale is simpler and faster. If you pay off the loan before completion, the property is no longer considered a Help to Buy property. This means you avoid the extra administrative steps and delays of getting approval from Homes England.
- It stops interest from accumulating. If you are past the initial five-year interest-free period, paying off the loan stops the interest from accumulating, potentially saving you a significant amount.
- You can repay at a fixed valuation. If you are selling in a falling market, you can repay the loan based on a valuation from before you listed the property for sale. The longer you wait, the more the value could fall, but it could also go up.
- It requires extra costs and administration. You will still have to pay for a separate Homes England-compliant valuation and a solicitor to handle the repayment. This is an additional process and cost.
What happens to the mortgage when selling a Help to Buy home?
When you sell a Help to Buy property, your existing mortgage must be paid off. You will use the proceeds from the sale to pay off your mortgage lender, and the remaining funds will be used to repay Homes England.
You can't transfer your loan to another property, so it will have to be repaid from the proceeds before you buy your next home.
You have a few options for your new mortgage when you buy your next property:
- Porting your mortgage: You can ask your current lender if you can "port" your existing mortgage to your new property. This allows you to keep the same interest rate and terms. However, your lender will need to re-evaluate your finances and approve you for the new property.
- Getting a new mortgage: You can get a new mortgage with a new or existing lender. This is often necessary if you cannot port your current mortgage, or if a better deal is available elsewhere.
Be aware of any early repayment charges (ERCs) on your existing mortgage. If you have to pay off your mortgage before the end of its term, your lender may charge a fee. This is a key cost to factor into your calculations when selling.

What happens if you can't afford to repay the loan from the sale proceeds?
If your property sells for less than its RICS valuation, or if you have fallen into negative equity, the sale proceeds alone may not cover both your primary mortgage and your Homes England repayment. When this happens, a financial shortfall is created. Because Homes England's legal charge remains tied to the RICS valuation figure (which dictates the true market value), you are legally obligated to fund this shortfall out of your own personal savings to complete the sale.
However, if you physically do not have the funds to bridge the gap, you cannot simply proceed with the transaction. Your conveyancing solicitor must pause the sale and formally apply to the Help to Buy Administrator for a Sale Under Value.
To grant permission to sell at a loss and release their legal charge, Homes England will not simply take your word for it. They will require extensive, undeniable proof that the lower price you accepted is the absolute ceiling of the current market. Your estate agent will need to provide:
- A comprehensive property marketing report showing exactly how long the home was listed.
- Proof of all viewings conducted and the specific feedback received from prospective buyers.
- Written evidence of all offers made, negotiated, and rejected.
- Confirmation that the property was actively marketed on major portals (like Rightmove or Zoopla) at a realistic asking price.
If Homes England accepts this evidence, they may agree to absorb their percentage share of the loss and issue the Authority to Complete. If they reject the evidence because they believe the property was undervalued or under-marketed, they will refuse to release their charge, meaning your property sale will legally fall through.
