Part Exchange: What You Need to Know
Part exchange with a property developer allows you to use your existing Harrow home as full or part payment for a new build property. The developer agrees to purchase your property at an independently assessed value, giving you a guaranteed, chain-free sale — eliminating the uncertainty and delay that often prevents homeowners from committing to a new build purchase.
The arrangement works because developers value the certainty of a chain-free buyer who can commit to a completion date. In exchange for that certainty, they typically offer 90-95% of independently assessed market value for your existing property — a smaller discount than a cash buyer in exchange for the added benefit of a new home.
Not all properties or transactions qualify for part exchange. Eligibility criteria vary by developer but typically your existing property must be worth no more than 70-75% of the new build purchase price and be in reasonable condition. We can assess your eligibility and match you with developers active in Harrow and the surrounding area.
Benefits of Part Exchange
Guaranteed Chain-Free Sale
The developer agrees to purchase your existing property as a condition of the new build transaction. There is no open market sale to manage, no chain to collapse, and no uncertainty about whether your existing home will sell in time.
Better Price Than Cash Buyer
Developers typically offer 90-95% of independently assessed market value — a smaller discount than a direct cash buyer (75-90%) because you are bringing them a guaranteed new build sale as part of the arrangement.
No Estate Agent Fees
Part exchange involves no estate agent commission on your existing property sale. The saving on a £400,000 property — typically £4,800 to £8,400 including VAT — partially offsets any discount on the part exchange offer.
Simplified Move
Moving directly from your existing home into a new build on a fixed completion date — without the stress of coordinating a chain, managing two sets of solicitors independently, or the risk of a broken sale disrupting your purchase.

How the Process Works
Eligibility Assessment
The developer assesses your existing property against their part exchange criteria — value relative to the new build price, condition, location, and tenure. Not all properties qualify; we can assess eligibility before making introductions.
Independent Valuation
The developer instructs two or three independent RICS-registered valuers to assess your property. The part exchange offer is typically based on the average of these independent valuations.
Part Exchange Offer
A formal part exchange offer is made — the price the developer will pay for your existing property, offset against the new build purchase price. You instruct a solicitor to review the offer and the new build purchase terms.
Simultaneous Completion
The sale of your existing property and the purchase of the new build complete simultaneously on the agreed date. You move directly from one to the other — with no gap, no bridging finance, and no chain.

Part Exchange FAQs
What Our Clients Say
“I needed to sell quickly after a divorce and couldn't face months on the market. The cash buyer they matched me with was professional, completed in 28 days, and the offer was far better than I expected. No estate agent fees either — it made a real difference.”
“I'd had my Pinner semi on with one agent for four months with barely any viewings. The agent they matched me with repriced it correctly, relaunched with better photos, and I had an offer accepted within three weeks. Should have switched sooner.”
“My property needed significant work and I knew a traditional sale would be difficult. Auction was the right route — competitive bidding pushed the price above my reserve and I had certainty of sale on the day. The whole process was explained clearly from the start.”
