Sitting Tenant, Standing Offer: A Landlord’s Route to an Agent-Free Sale in 2026

For a landlord, an off-market sale to the person already paying rent has obvious appeal: no agency fee, no void period, no parade of strangers at viewings. Yet the arrangement is rarely a single transaction. It is a property sale and a tenancy unwind running on parallel clocks. Handled with discipline, it can be clean and cost-effective. Handled casually, it can produce a disputed deposit, a failed mortgage application and a completion date that suits neither side.

First, decide what you are actually selling

There are two distinct products. The first is a home with vacant possession, where the tenant is the buyer and the tenancy ends at or before completion. The second is a tenanted investment, where the tenancy continues and the buyer steps into the landlord’s shoes. The price, the paperwork and the pool of viable buyers differ sharply between the two.

A tenant buyer will usually need a residential mortgage and will want the tenancy surrendered before completion. An investor buyer may accept the existing tenancy, but will price the property on yield and risk. Before either route is pursued, establish whether the tenant has a mortgage decision in principle and whether the lender accepts the proposed structure. Some lenders are wary of sitting tenants; others will not lend where a tenancy has not been properly ended. For leasehold flats, check the headlease and freeholder requirements before assumptions harden.

Building a price both sides can defend

Without an agent, there is no intermediary to anchor expectations. The seller should therefore prepare a valuation file rather than a single figure. Include three to five completed sales within a reasonable radius, adjusted for condition, floor area and tenure, together with rental comparables if the property is to be sold tenanted. Share the method as well as the number. A tenant who can see how the figure was reached is more likely to negotiate on evidence rather than sentiment.

A joint instruction to an independent surveyor can be useful where the gap between asking and offering is wide, but it should not be treated as binding. Keep the agreed price subject to survey and contract, record what is included — white goods, fixtures, garden equipment — and put an expiry date on the offer. Rent paid reliably for years is evidence of affordability, not evidence of value.

The deposit is not a bargaining chip

The tenancy deposit must follow the rules throughout. If the tenancy ends, the landlord must return the deposit, or agree deductions, within the statutory timescale; for an AST in England and Wales, that is generally ten working days after the amount is agreed. If the tenancy is assigned to a new landlord, the deposit must be protected in an approved scheme within thirty days and the prescribed information given to the tenant. A deposit should never be used as a discount, a holding fee or a completion incentive without the scheme rules being followed and the transaction documented by solicitors.

Where the tenant is buying, any proposal to apply the deposit to the purchase price should be treated as two separate steps: the deposit is first returned or accounted for under the tenancy rules, and only then is any sum applied to the purchase. Keep rent accounts and completion statements separate so that the paper trail remains clear.

Gazumping, gazundering and the lock-out

Private sales are exposed to second thoughts. A lock-out agreement — an exclusivity period for a fixed term, supported by consideration — can discourage the seller from marketing to others while the buyer pays for survey and legal work. It is not a guarantee of completion, and it should be drafted by a solicitor. A reservation fee can also concentrate minds, but it must be handled carefully and transparently.

More effective than any informal promise is pace. Instruct solicitors early, assemble the contract pack, obtain a mortgage decision in principle, book the survey and agree a timetable with dates. Confirm in writing that the seller will not market the property for an agreed period provided the buyer meets stated milestones. That gives the tenant buyer something an outside bidder cannot easily replicate: certainty of access and knowledge of the property.

Ending the tenancy without derailing completion

If the tenant is buying, the tenancy should end by surrender or by the expiry of a notice, not by improvised agreement on the day of completion. A deed of surrender effective on completion can align the two events, but it needs legal drafting. Where a fixed term remains, a surrender agreement is usually required. Where the tenancy is periodic, the correct notice must be served and its expiry diarised.

A Section 21 notice should not be used as a pressure tactic in a sale to the tenant. It introduces unnecessary risk and can poison a negotiation that depends on cooperation. If the buyer is an investor and the tenancy continues, the seller should prepare an assignment of the landlord’s interest, a rent statement, the deposit certificate and a letter to the tenant confirming the new landlord’s details.

The legal overlap: one file, two clocks

The conveyancing file and the tenancy file must be reconciled. Tell the solicitor at the outset that the buyer may be the tenant. Provide the tenancy agreement, deposit certificate, prescribed information, rent statement, inventory, gas safety record, electrical installation condition report, EPC and any building regulations or planning documents. The tenant buyer should have independent legal advice; the seller’s solicitor should not act for both sides.

Completion should be aligned with the end of the tenancy, rent apportionment, meter readings, keys and council tax. If the property becomes vacant before completion, notify the buildings insurer, because standard cover may not apply to an empty home.

Tax and practical housekeeping

A residential property disposal may require a capital gains tax return and payment within sixty days of completion. Principal private residence relief is unlikely to cover a property that has been let, so take accountancy advice before exchange rather than after. Service charge apportionments, ground rent and utility accounts should be scheduled alongside the sale statement.

A short checklist

• Confirm whether the sale is with vacant possession or subject to tenancy.
• Check the tenant buyer’s mortgage position before agreeing terms.
• Prepare a valuation file and share the method, not just the figure.
• Record the offer in writing, subject to contract and survey, with a timetable.
• Protect, return or transfer the deposit strictly under the scheme rules.
• Instruct solicitors early and insist on separate representation.
• Draft a deed of surrender or assignment well before completion.
• Align completion, rent, keys, meters and insurance.

A direct sale to a sitting tenant can remove the agency fee and the uncertainty of the open market. It does not remove the need for structure. The saving is earned through preparation, not haste.
