Sell first or buy first?

There is no universally right order. There is a right order for your market, your equity and your tolerance for disruption. The three routes look like this.

Selling first

You complete the sale, bank the equity, and house-hunt as a chain-free buyer with cash evidence and an Agreement in Principle (AIP, the lender-issued indication of what you can borrow) in hand. Agents take you seriously and vendors often accept slightly lower offers from buyers who cannot fall through. The cost is the gap: short-term renting, storage, and moving twice. In a rising market you also carry the risk that prices move away from you while you rent.

Buying first

You secure the next home before your current one sells. That needs one of two financing routes. Chain-break or bridging finance is a short-term loan secured on property that covers the purchase until your sale completes. Let-to-buy keeps the current home: you switch its mortgage onto a buy-to-let basis, rent it out, and release equity toward the next deposit. Both routes have real costs and real criteria, and buying first also means completing the purchase while you still own the old home, which triggers the 5% additional-property surcharge on Stamp Duty Land Tax (SDLT). On a £400,000 purchase that is £20,000 fronted. The surcharge is normally refundable if you sell the previous main home within three years, but the cash still has to be found on completion day.

The simultaneous chain

The standard route: your sale and purchase complete on the same day, the equity passes straight through, and you move once. The price is dependency. Every link in the chain can delay or collapse yours. The practical defences are preparation: sale agreed before you offer, AIP issued, solicitor instructed, paperwork ready, and a broker chasing the mortgage side weekly.

Reading your local market

In a market where homes sell in days, buying first is less risky because your sale will catch up. In a slow market, selling first is the stronger play because your sale is the uncertain half. Days-on-market for your street and price band, which we can look at with you, tells you which side of that line you are on.

Common pitfalls we see

Offering before the current home is under offer and being treated as a weak buyer. Underestimating the full cost of buying first once the surcharge, bridging interest and double running costs are added up. Accepting a low sale price under time pressure that costs more than six months of patience would have. Sequencing is a numbers decision, so we put the numbers in front of you first.
