Block Sale vs Individual Sales: What's the Difference?
When you own several properties and decide to sell, you can sell each property individually on the open market, or sell the portfolio – or a defined part of it – to one buyer in a single transaction. Understanding the differences helps you decide what suits your circumstances.
Block Sale (Portfolio Transaction)
- One buyer and one negotiation
- Exchange and completion coordinated across the properties
- Commonly takes several months for a portfolio
- One solicitor can usually act on all properties
- Price agreed for the portfolio as a whole
- Off-market – not advertised on public portals
- Investor buyers used to multi-property purchases
- Tenanted properties can be included
- If the buyer withdraws, the whole sale is affected
- A single-buyer price may be lower than the sum of individual open-market sales
Individual Sales (Estate Agent Route)
- ⚠ Multiple buyers, multiple negotiations
- ⚠ Each property completes separately – often months apart
- ⚠ The overall timescale depends on the slowest sale
- ⚠ Multiple sets of legal costs, surveys, searches
- ⚠ Some sales may fall through while others proceed
- ⚠ Properties are advertised publicly, with viewings for tenants to accommodate
- ⚠ Each sale progresses on its own timetable
- ⚠ Tenanted properties may not suit owner-occupier buyers
| At a glance | Whole portfolio to one buyer | Each property sold separately |
|---|---|---|
| Buyers | Investor buyers used to multi-property purchases | A mix of owner-occupiers and investors, property by property |
| Tenants | Usually stay in place | Owner-occupiers usually need vacant possession |
| Marketing | Off-market, to buyers under NDA | Public portals, boards and viewings |
| Price | One price for the portfolio, based on income and condition; may be below the total of individual open-market sales | Each property priced on its own; can achieve more per property, after longer marketing and more costs |
| Timescale | Commonly several months for the whole sale | Varies by property; the exit ends with the slowest sale |
| Costs | One coordinated legal process, though each title still needs work | Separate agent and legal fees, surveys and searches for each sale |
| Risk | If the buyer withdraws, the whole sale is affected | Some sales may fall through while others proceed |
| Tax timing | Gains usually fall in one tax year | Gains can fall across tax years; take advice |
General comparison only. Price depends on the properties, tenancies, condition and the buyer's funding. See our guide to Capital Gains Tax when selling rental property.
The Legal Complexity of Selling Multiple Properties
Selling several properties together involves more legal work than a single sale. Understanding what is involved – and instructing solicitors with experience of multi-property transactions – helps the sale run more smoothly.
Multiple Land Registry Titles
Each property normally has its own Land Registry title, and each title must be checked, reported on and transferred. A portfolio of twenty properties means twenty sets of title checks and transfers. Solicitors experienced in portfolio work run these in parallel where they can.
Mortgage Redemption Coordination
If your properties carry buy-to-let mortgages – possibly with several lenders – each mortgage is normally redeemed at completion. Your solicitor obtains redemption figures from each lender, including any early repayment charges, and deals with redemption on completion. Speak to your lenders early about their requirements.
Tenancy Schedule Transfer
Tenancy agreements, deposit protection records, gas and electrical safety records, EPCs and related documents will be needed by the buyer. Keeping accurate, organised records saves time at this stage. We can tell you what buyers typically ask to see so you can prepare in advance.
Completion in Tranches
For larger portfolios, a buyer may propose completing in stages (tranches) rather than all at once. Any staged completion would be agreed between the parties and documented by the solicitors.
Stamp Duty for the Buyer
The buyer pays any Stamp Duty Land Tax due on the purchase, and their tax position can affect what they are prepared to offer. Buyers take their own advice on this.
Title Defects Across the Portfolio
In a larger portfolio, one or two properties may have title issues – missing documents, short leases, restrictive covenants or planning irregularities. These need to be identified and dealt with by the solicitors, which may involve indemnity insurance or removing a property from the sale. Raising issues early reduces the risk of delay.
Tax Points to Discuss With Your Adviser
Selling several properties can have significant tax consequences. The points below are general and factual only. Tax and legal treatment depends on your circumstances. Speak to a qualified accountant or solicitor before acting.
Capital Gains Tax
Capital Gains Tax (CGT) may be payable on the gain on each property – broadly, the sale price less the purchase price and allowable costs. For 2026 to 2027, the rates are 18% on gains within the basic-rate band and 24% above it, and the annual exempt amount is £3,000 (GOV.UK, "Capital Gains Tax rates").
Tax treatment depends on your circumstances. Speak to a qualified accountant before deciding how and when to sell.
Properties Held in a Limited Company
Portfolios held in a limited company can be sold either by selling the properties (an asset sale) or, in some cases, by selling the company's shares. The right route depends on your circumstances – your solicitor and accountant will advise. Any proposal involving the sale of company shares is checked by a solicitor before details are shared or promoted.
Inheritance Tax
Selling property changes the make-up of your estate. If inheritance tax is a consideration for you, take advice from a qualified adviser before any sale.
VAT
Residential property sales are generally exempt from VAT. Portfolios that include commercial property may raise VAT questions, such as whether an option to tax applies. Your accountant and solicitor will advise.

Frequently Asked Questions: Selling Multiple Properties
A block sale – also called a portfolio sale – means selling two or more properties to one buyer in a single coordinated transaction. Selling each property individually involves separate buyers, negotiations and completions, which can take longer overall and means each sale progresses on its own timetable. Which route suits you depends on your properties and circumstances.
Capital Gains Tax is charged on the gain on each property you sell, whether the properties are sold together or separately. For 2026 to 2027, the rates are 18% on gains within the basic-rate band and 24% above it, with an annual exempt amount of £3,000 (GOV.UK, "Capital Gains Tax rates"). Tax and legal treatment depends on your circumstances. Speak to a qualified accountant or solicitor before acting.
Not usually. Many sellers instruct one solicitor or conveyancing firm to act on all the properties, which can make coordination simpler. It is sensible to choose a firm with experience of multi-property transactions and the capacity to deal with several titles at once. You pay your own solicitor's conveyancing costs.
Yes, a partial sale is possible – for example, a group of properties in one area, while you retain others. Whether a partial sale suits you can depend on your lender's terms and your tax position, so speak to your lender and a qualified accountant before deciding.
