Landlord Exit Strategy: Selling Part or All of Your Portfolio

If you plan your exit like you planned your acquisitions, you keep more of the gain and avoid a 2-year slog of messy sales and tax surprises. If you leave it to chance, HMRC and voids eat a big chunk of your "pension".

1. CGT in 2026-27: the rules you are playing with

For 2025-26 and 2026-27, each individual gets an annual CGT exemption of GBP 3,000.

It is use it or lose it. You cannot carry unused allowance forward.

Couples can use two allowances (GBP 6,000) if both own the asset or you transfer a share to your spouse before sale.

CGT rates on residential property gains for individuals in 2026-27:

Gains falling in your basic-rate band: 18%.

Gains above that: 24%.

TCGA 1992 still governs the basic mechanics of chargeable gains, pooling and share identification, with the newer rates and allowances overlaid by recent Finance Acts.

What this means in practice:

The GBP 3,000 annual exemption now saves at most GBP 540-720 per person per year on residential gains (18-24% of GBP 3,000).

It is still worth using if you can spread disposals, but it is not worth dragging a portfolio disposal out 10 years solely to chase this.

Timing and spouse transfers

If you can stagger a planned disposal over 2 tax years, you can usually shelter GBP 6,000-12,000 of gains with one or two owners.

A no-gain/no-loss transfer to a spouse or civil partner before sale lets you use two annual exemptions and potentially more basic-rate band.

You only do this where it fits your wider tax position and your accountant is on board.

2. Decision framework: which properties to sell, and in what order

You are deciding:

What to sell.

When to sell.

How to sell.

What to sell first

In most cases you start with:

Worst performers: low net yield, high hassle, big future capex (old roofs, EPC upgrades).

Non-core locations: outliers that complicate your management.

Properties that tie up equity with poor return: low-yield South-East stock, flats with rising service charges.

You keep (or sell last):

High-yield, low-hassle units in strong rental areas.

Properties with clear future upside (regeneration, station openings, obvious uplift angles).

High-gain vs low-gain properties

Forum myth: "You should sell low-gain properties first and leave the big gains until last so they grow tax-free longer."

Reality: with a GBP 3,000 allowance and 18/24% rates, the order often matters less than:

Using both spouses' allowances.

Keeping yourself out of 24% on as much as possible by managing your income and timing.

You work with your accountant to sequence sales so total gains and other income each year use as much basic-rate band as possible at 18% rather than 24%, within the practical limits of your tenant and market situation.

3. How to sell: tenants-in-situ vs vacant, portfolio vs piecemeal

Selling with tenants in situ

Selling to another landlord with tenants in place gives:

Income continuity up to completion.

Appeal to investors who want immediate rent and no letting costs.

Faster process (no need to evict or refurb between tenancies).

But:

Buyer pool is mostly investors only, not owner-occupiers.

In some markets, investors expect a slight discount versus vacant value to reflect lower flexibility and existing tenancy terms.

This can work well if:

Tenants are paying market rent,

ASTs and compliance are clean,

You market specifically to investors / portfolio buyers, not just via standard residential agents.

Selling with vacant possession

Wider buyer pool including owner-occupiers.

Often gets you a higher price than selling with tenants (especially for family homes).

But:

You lose rent during notice, any refurbishment, and marketing.

Under the new Renters' Rights regime (longer notice, ground-only possession), it may take longer to regain possession and you must plan that into your timeline.

For the guide you can keep it practical:

If the asset is most likely to be bought by an owner-occupier (standard houses in suburban streets), vacant possession usually wins.

If it is a pure investment (blocks, HMOs, commercial), you will often do better selling to investors with tenants in situ, or selling the company or block as a whole.

Selling a property company (share sale) vs property (asset sale)

If your portfolio sits in a limited company, you can sell:

Assets: the company sells properties.

Company pays corporation tax on gains.

You then face tax on extracting the proceeds (dividends, liquidation).

Shares: you sell shares in the company to the buyer.

Buyer avoids SDLT on individual property transfers, which can justify a higher price than an asset sale because they save stamp duty.

You pay CGT on share disposal under TCGA 1992 share rules and s104 pooling, with rates 10/20% (non-residential) or appropriate rate if it is mainly residential and falls within the residential regime.

For share sales the Section 104 pool rules in TCGA 1992 aggregate acquisitions of shares of the same class in the same company, so your base cost for CGT is the pooled amount, not each tranche.

For buyer and seller, a properly priced share sale can be win-win:

Buyer saves SDLT and takes over loans and structures.

Seller can negotiate a slightly higher headline price to share that stamp saving.

You need specialist advice here; it is not a DIY move.

4. Practical timeline: how long a portfolio exit actually takes

From "I want out" to money in your account is usually 6-18 months for a serious portfolio exit, sometimes longer.

Typical steps:

Year 1 planning (0-3 months)

Portfolio review with accountant: which to sell, which to keep, rough order.

CGT modelling over 2-3 tax years using current rates and allowances.

Tenant strategy (0-6 months)

Decide per unit: sell with tenants or seek vacant possession.

For vacant sales, start possession steps in line with current Renters' Rights regime (ground-based, longer notice).

Build in time for potential court delays.

Marketing phase (3-12 months)

Investor sale route:

Use agents who specialise in tenanted portfolios, or auction / portfolio marketplaces.

Retail sale route:

Standard high-street or online agents, staged viewings, possible refurb.

Exchange and completion (2-4 months per property / block)

Once offer agreed, legals, buyer finance and searches take time, especially on complex, tenanted or company sales.

Realistic expectation: if you decide in mid-2026 to exit a 10-unit portfolio with mixed tenants, you are probably looking at 2027-28 for full completion unless you take a sharper investor price or auction route.

5. Reinvestment and de-risking: what happens next

Once you sell, you are sitting on cash after CGT and costs. Options include:

Paying down other mortgages

Immediate risk reduction and improved cashflow on the remaining portfolio.

Commercial property

Different tax profile (inside company), different tenant risk, but also different void/rent profile.

Equities / funds

CGT on shares and funds is at 10/20%, not the 18/24% residential rates, so after a residential portfolio sale some investors diversify into ISAs, general investment accounts, and pensions.

Pension contributions

Using sale proceeds to maximise pension allowances can convert some of the capital into income-tax-efficient long-term wealth.

Your exit guide should make one point very clear: there is no rule that says you must roll every pound into more property. The right exit strategy often includes shrinking leverage and diversifying risk, not just buying different bricks.

6. What forums get wrong about portfolio exits

The myths to kill in your PropertyKiln piece:

"Just drip-feed one property a year to use your CGT allowance."

At GBP 3,000 per person per year, stretching a 10-property exit over 10-15 years just to use the exemption is rarely worth it.

Better to line disposals up with market conditions, CGT rates and your life plans, using exemptions where they naturally fit.

"You always get more selling with vacant possession."

You often get more for family houses that way, but selling tenanted units or full portfolios to investors can achieve strong prices when the income and compliance stack up, and you avoid long voids and refurb costs.

"Just sell the company, it's tax-free for the buyer so they'll pay a fortune."

Buyers will still price in:

Embedded tax,

Loan terms,

EPC/compliance risk,

Tenant profile.

A share sale can add value, but it is not a blank cheque.

"You can always change your mind and keep good properties later."

Once you have started serving notices and unsettling tenants, you are burning goodwill and stability.

Exit decisions are hard to reverse without losing income or reputation.

For PropertyKiln, the position to take is:

You do not "retire" from property in one weekend. You phase out the worst stock first, use the current 18/24% CGT regime and GBP 3,000 allowances intelligently, and manage tenants and timelines so you take money off the table without blowing up your last 5-10 years of cashflow.
