Selling a Buy-to-Let property: Guide for landlords

More landlords are selling up than at any point in the last decade. Higher mortgage rates, the loss of full mortgage interest relief and the arrival of the Renters’ Rights Act have all pushed owners to take a hard look at their portfolios. If you have decided the time is right, selling a buy to let is a different job from selling your own home, and it pays to understand where the differences lie before you instruct anyone.

This guide walks through the whole process, from the decisions you need to make about your tenants through to tax, conveyancing and completion.

First decision: sell with tenants in place or sell empty?

Everything else flows from this choice. Sell with the tenancy running and your buyer will almost certainly be another investor, because the property comes with a sitting tenant and the rental income attached. Sell with vacant possession and you open the sale up to owner occupiers, who usually pay more, but you first need to bring the tenancy to an end lawfully.

Since 1 May 2026 that second route takes longer than it used to. Section 21 notices are gone, and a landlord who wants possession in order to sell must rely on the selling ground under the Renters’ Rights Act, which requires at least four months’ notice and cannot be used during the first year of a tenancy. We cover the detail in our separate article on selling with tenants in situ, but the short version is this: plan your timeline early, because the days of serving two months’ notice and listing the property the following week are over.

Get your paperwork together before you list

Buy-to-let sales fall apart on paperwork more often than on price. Before the property goes on the market, dig out or arrange the following:

• A valid Energy Performance Certificate. You cannot market the property without one, and rental properties face tightening minimum standards.

• The tenancy agreement, deposit protection certificate and prescribed information, if you are selling with tenants in place.

• Gas safety records, electrical installation condition report and any licensing documents if the property is in a selective or HMO licensing area.

• Leasehold papers if the property is a flat, including the lease itself and details of ground rent and service charges.

A buyer’s solicitor will ask for all of this during conveyancing. Having it ready at the start can shave weeks off the transaction.

Understand the tax before you agree a price

When you sell a rental property you will usually owe capital gains tax on the profit. For the 2026/27 tax year, gains on residential property are taxed at 18 per cent for basic rate taxpayers and 24 per cent for higher and additional rate taxpayers, and each person has a tax free annual exempt amount of £3,000. The official rules are set out on the government’s tax when you sell property pages.

Two points catch landlords out. First, you must report and pay the tax within 60 days of completion, not at the end of the tax year. Second, the gain is calculated on the difference between what you paid and what you sold for, adjusted for buying costs, selling costs and capital improvements, so keep every invoice. If the property is jointly owned, both owners use their own allowance and rate bands, which can make a meaningful difference to the bill.

Instructing a solicitor for a buy-to-let sale

Any residential conveyancer can technically handle the sale, but landlord conveyancing has its own wrinkles and it is worth choosing a firm that deals with investment property regularly. A good selling rental property solicitor will know how to handle the tenancy side of the transaction, including serving the right notices on the tenant, apportioning rent at completion and transferring the deposit protection to the buyer if the tenant is staying.

If the sale is tenanted, the contract needs to deal with the tenancy expressly. The buyer takes over as landlord on completion, and sloppy drafting around rent arrears, deposit liability or outstanding repair obligations is a common source of disputes after the sale. If the sale is with vacant possession, your solicitor needs to be satisfied that the tenants really will be out by completion, because you are contractually on the hook if they are not.

Fees for a straightforward freehold sale typically run from around £800 to £1,500 including VAT, with leasehold sales costing more because of the extra paperwork. Comparing a few quotes takes minutes and the spread between firms can be several hundred pounds. You can compare conveyancing quotes on Moving Compared and see fees from vetted firms side by side.

The sale process step by step

1 - Valuation and agent selection

Get at least three valuations. If you are selling tenanted, ask agents specifically about their experience with investor buyers, because marketing a tenanted property through an agent who only deals with owner occupiers rarely ends well.

2 - Marketing and viewings

Tenants are entitled to quiet enjoyment of their home. You need to agree access for viewings rather than assume it, and a cooperative tenant is worth a great deal, so give plenty of notice and consider being flexible on timing. Some landlords offer a small rent reduction during the marketing period in exchange for access and a tidy property.

3 - Offer, conveyancing and enquiries

Once you accept an offer, the legal work begins. Expect enquiries about the tenancy, licensing, safety certificates and any works done to the property. The process follows the same broad shape as any sale, which we explain in our complete guide to conveyancing, but with the tenancy documents layered on top.

4 - Exchange and completion

At exchange the deal becomes binding. If the property is sold tenanted, rent is apportioned to completion day and the deposit transfers to the buyer’s scheme. If it is sold vacant, make sure the tenancy has actually ended and the tenants have returned the keys before you commit to a completion date.

How long does it all take?

A tenanted sale to an investor can complete in eight to twelve weeks, much like a normal transaction. A sale with vacant possession is now a longer project: four months’ notice under the selling ground, possibly a court application if the tenant does not leave, then marketing and conveyancing on top. Landlords who want to sell in the spring should realistically be starting the process the previous autumn.

Final thoughts

Selling a buy to let rewards preparation. Decide early whether the tenancy stays or goes, get the compliance paperwork straight, budget for capital gains tax and the 60 day deadline, and put the legal work in the hands of a conveyancer who handles rental property week in, week out. Do those four things and the sale itself is rarely dramatic.
