How quickly can a flat sale be completed when selling as-is for cash?
An as-is cash sale of a flat can often be completed in days, provided the buyer’s funds, the title and the flat’s legal paperwork are in order. The exact timescale depends on checks such as the lease, management information, property searches and any issues affecting ownership or the transaction.
An as-is cash flat sale is completed on the date agreed by the buyer and seller’s solicitors, when the purchase money has been transferred and ownership can pass. The condition of the flat does not usually determine the completion date, but legal checks, leasehold information and any unresolved issues with the title can extend the process.
A typical transaction progresses through several stages:
- Offer and initial information: The buyer confirms the proposed price and the seller provides basic details about the flat, including its tenure, lease term, known defects, occupier status and any mortgage secured against it.
- Instruction of conveyancers: Both parties appoint solicitors or licensed conveyancers. The seller’s conveyancer prepares the contract pack, while the buyer’s conveyancer begins reviewing the title and raising enquiries.
- Leasehold investigations: Most flats are leasehold, so the buyer will usually need information about the lease, ground rent, service charges, buildings insurance, planned major works, reserve funds and managing-agent arrangements. The managing agent or freeholder may need to supply documents before the buyer’s legal checks can be completed.
- Searches and enquiries: Local authority, drainage and environmental searches may be required, depending on the buyer’s circumstances and the property. Enquiries can also cover alterations, building regulations, fire-safety information, rights of access, disputes and restrictions in the lease.
- Mortgage and title matters: If the seller has a mortgage, the lender must provide a redemption figure so it can be repaid from the sale proceeds. Any restrictions, missing documents, ownership discrepancies or probate requirements may need resolving before exchange.
- Exchange and completion: Exchange of contracts makes the agreement legally binding and fixes the completion date. Completion takes place when the balance of the purchase price reaches the seller’s solicitor, after which keys and possession are released in accordance with the contract.
Cash funding can remove the buyer’s mortgage application and lender valuation from the process, which may simplify the transaction. It does not remove the need to establish that the seller owns the flat, that the lease is transferable and that any charges or restrictions can be dealt with. A cash buyer may still commission a survey or carry out inspections, although an as-is purchase generally means the buyer is not asking the seller to carry out repairs as a condition of the agreement.
Leasehold information is one of the most common causes of delay. Problems may arise where the lease has a short remaining term, the service-charge account is not up to date, major works have been proposed, consent for alterations is missing, or the managing agent has not supplied replies to the standard enquiries. A buyer may also need confirmation that service charges and ground rent are paid up to the completion date and that any apportionments are correctly calculated.
The transaction can also take longer if there is a chain, an absent freeholder, a registered charge that has not been released, several owners who must sign, an ongoing probate process or a tenant whose occupation affects possession. Flats affected by cladding, fire-safety concerns, enforcement action or disputes may require additional documents and professional advice before the buyer is willing to proceed.
Sellers can help keep the transaction moving by instructing a conveyancer familiar with leasehold sales, locating the original lease and guarantees, supplying identification promptly and being open about defects or previous alterations. It is also sensible to request the management information early, check whether consent was obtained for alterations and obtain an up-to-date mortgage redemption statement where relevant. These steps do not guarantee a particular completion date, but they can reduce avoidable requests once the buyer’s legal work begins.
The most reliable indication of timing comes after the buyer’s conveyancer has reviewed the contract pack, searches and leasehold replies. Until those checks are complete and contracts have been exchanged, a proposed completion date remains subject to change.

The agreed completion date also depends on the seller being ready to hand over the flat in the condition required by the contract. Where vacant possession is required, tenants and other occupiers must have left, personal belongings should be removed and any agreed fixtures or fittings must remain. A failure to meet these practical requirements can prevent the buyer from taking possession even when the legal paperwork is otherwise complete.
Sellers should therefore coordinate removals, key handover, meter readings and access arrangements before the target date. It is sensible to confirm with the conveyancer exactly what must be left at the property and when keys will be released. These details do not usually lengthen the legal work itself, but dealing with them early helps prevent a last-minute problem on completion day.
