Buying and Selling a House at the Same Time

Get sale ready before you need to be

The single most effective step in managing a simultaneous sale and purchase is becoming sale ready before you accept an offer, not after. Instruct a solicitor early and complete the property information and fittings forms in advance, since these are routinely the cause of delay once a sale is agreed, far more often than the survey itself.

Having your mortgage offer, proof of deposit and identification documents ready in advance for the purchase side has the same effect, removing steps that otherwise only start once an offer has already been accepted.

Understand the chain you are in

Ask your estate agent directly how many parties sit above and below you in the chain, since each additional link increases the risk of delay and typically adds a couple of weeks to the time it takes to reach exchange. A first time buyer below you with no chain, and a seller above you who has already found their next property, both reduce risk considerably compared with a long chain on both sides.

Bridging finance and part exchange

Bridging finance lets you complete a purchase before your sale has gone through, which breaks the chain dependency but comes at a real cost in interest and fees. It is generally used only where the alternative, renting between properties or risking the chain collapsing, is clearly worse, and it is worth getting a clear cost comparison from a broker before committing to it.

Part exchange, offered by some new build developers, removes chain risk entirely by having the developer buy your current home directly, usually at a price below full open market value in exchange for certainty and speed.

Timing exchange and completion

Exchange of contracts is the point at which the transaction becomes legally binding, and completion is when money moves and keys are released. Many buy and sell transactions aim to exchange with a short gap before completion, giving a small buffer to confirm removals and handle any last minute issues, though same day exchange and completion is also common.

Protecting moving day

Book removals with a flexible cancellation and date change policy, since completion dates on chain transactions can move at short notice even close to the day. Ask whether the removals company can offer overnight storage on the vehicle if keys are released later than expected, which keeps your belongings secure without needing to unload into a driveway or street.

It is also worth keeping a small bag of essentials, medication, chargers, a change of clothes and important documents, separate from the main load in case the day runs later than planned.

What to do if dates slip

If a date in the chain slips shortly before completion, contact your solicitor immediately to understand the new likely timescale, and update your removals company as soon as you have a revised date, since most companies would rather reschedule than lose the booking. Avoid committing to non refundable costs, such as some utility connection fees or cleaning bookings, until the completion date is confirmed with reasonable certainty.
