Stages of a Sale at a Glance
A typical open-market leasehold flat sale moves through four stages from instruction to completion. Total elapsed time is usually 8 to 14 weeks, though some stages run in parallel and the picture varies considerably by complexity.
Weeks 1 to 2: Listing and marketing
Estate agent instructed, EPC produced (or refreshed if expired), professional photos taken, marketing materials drafted. Property goes live on the major portals. Initial enquiries and viewings begin. In a strong market with a well-priced flat, an offer can come in within days; in a slower market or for a flat with complications, this stage can extend.
Weeks 3 to 6: Offer accepted, conveyancing begins
Offer agreed, memorandum of sale issued, both sides instruct solicitors. The seller's solicitor requests the leasehold management pack (LPE1) from the managing agent, draws up the contract pack, and sends it to the buyer's solicitor. The buyer's lender (if mortgage-backed) instructs a valuation survey.
Weeks 6 to 10: Enquiries and searches
The buyer's solicitor reviews the contract pack, sends pre-contract enquiries, receives local authority and other searches, and reviews the lease and any unusual provisions. The seller (or solicitor) responds to enquiries. The buyer's lender issues the formal mortgage offer. This stage is the most common source of delay because of the back-and-forth on enquiries and the wait for managing agent responses.
Weeks 10 to 14: Exchange and completion
Once enquiries are satisfied and finance is in place, the contracts are dated, signed, and exchanged. A completion date is fixed (typically 1 to 4 weeks after exchange). On completion day, funds transfer, keys hand over, and the sale is final.
