Selling a house can be expensive, and Shared Ownership is no different. The costs include: Valuation fee EPC fee Nomination fee (1% of sale price payable to Cornerstone) Administration fee £250.00 (payable to Cornerstone if marketed by an estate agent and not us) Private management company fee to answer enquiries (if applicable) Legal fees

How long does a sale take?

Once a buyer has been found, it’s normally around 12 weeks to complete the purchase, but if you are both buying a new home you may need to be flexible with these times. Cornerstone is not typically involved in agreeing dates, and these are negotiated between you and the buyer. We would advise that you liaise with your solicitor regularly in order to progress the sale with your buyer’s solicitor in good time.

What happens if I don’t agree with the RICS valuation?

If you have serious concerns that your home has been under or over valued, we can approach the surveyor on your behalf. However, we will need three comparable valuations of similar properties that have sold within the last three months to query the valuation.

When should I look for another house?

You can begin looking for another house whenever suits you, but you should avoid making an offer on another house until a buyer has agreed to purchase your property. You and the buyer will then be able to agree timescales for completion of the purchase.

What if the sale falls through?

If the sale falls through, Cornerstone will readvertise your property. If this is outside of the nomination period, you can market the property yourself via an estate agent of your choice.

Thinking Of Selling Your Shared Ownership Property

What You Need to Know About Selling

Selling a shared ownership home is different from selling a property you own outright. There are some extra steps and costs involved. This page explains the process and what you need to do if you want to sell your shared ownership home with Cornerstone.

We understand that selling your home can feel complicated. We’re here to help guide you through the process and answer any questions you have along the way.

The Selling Process

Selling your Shared Ownership home is slightly different to selling an open market property. We’ve summarised the process in five steps.

You will need a valid Energy Performance Certificate (EPC). You will need to arrange and pay for the EPC if you don’t have one in date. To check whether yours is still in date, visit Find an energy certificate – GOV.UK

Once you are in receipt of the EPC and valuation you will need to send this over to us, along with photographs of your property and any information you think is relevant for marketing.

We will then send you a form to sign, outlining the agreed share price and requesting your solicitor’s contact details.

Please note that it is recommended to use a solicitor who is knowledgeable in shared ownership sales to ensure your sale goes smoothly.
We will market your property on your behalf (Cornerstone has a nomination period of 8 weeks to sell the property). We will advertise on our own website, as well as Rightmove, Zoopla, Share to Buy and Solo Homes.

Once a buyer has been found and initially approved (depending on local connection, if required), we will arrange for them to view the property with you.
If a buyer is found within the nomination period, once approved, we will send the Memorandum of sale to you, your solicitors and the buyer’s solicitors.

If no sale has been agreed within the nomination period, you can choose to market your property with an estate agent or continue the marketing with Cornerstone.

Purchasers can buy further shares at the same time as buying your share or the 100% of the property, known as simultaneous sale and staircasing.
