When a buyer submits an offer to acquire your letting agency, the document they send contains considerably more than a headline number. Sellers who focus on that number alone will sometimes accept a lower economic outcome than they could have achieved, simply because they did not understand what the offer actually contained or what they were entitled to negotiate.
This guide breaks down the components of a typical letting agency acquisition offer, explains how to compare different buyer types on a risk-adjusted basis, and covers the practical steps involved in responding effectively. For a complete overview of the sale process, see how to sell your estate agency. For guidance on how the underlying valuation is calculated, see our estate agency valuation guide.
What a Letting Agency Offer Contains
A well-structured offer addresses six elements. Understanding each separately is the starting point for evaluating it properly.
The AMFI multiple. The headline valuation is expressed as a multiple of Annual Management Fee Income — the recurring income your portfolio generates from managed landlords. A multiple of 2.5x applied to £200,000 AMFI produces a headline value of £500,000. The AMFI figure itself matters as much as the multiple: buyers sometimes apply their own AMFI calculation in the offer, which may differ from the figure used in your own valuation. Before accepting any offer at face value, confirm that the buyer’s AMFI figure matches your records.
The completion payment. The proportion of the headline value paid on the day the transaction completes. For individual buyers, the completion payment is typically 100% of the agreed price. For corporate and PE-backed acquirers, the completion payment usually represents 60–70% of the headline, with the remainder deferred as an earn-out.
The earn-out. The deferred consideration paid after completion, conditional on the managed portfolio maintaining its income over an agreed period. Earn-out terms — the AMFI definition, measurement period, targets, and protections — are the most complex element of any offer and the most negotiable.
Conditions. Offers are typically conditional on satisfactory completion of due diligence, financing confirmation, and sometimes a specific audit of management agreement documentation. Conditions determine how firm the offer actually is.
Exclusivity. The period during which you agree not to engage with other potential buyers while the transaction progresses. Exclusivity is a concession that has genuine value; treat it as something to be traded, not simply accepted.
Transaction structure. Whether the deal is structured as an asset purchase or a share purchase affects the tax treatment, the lease position, and how liabilities are allocated. Most letting agency acquisitions are structured as asset sales, in which the buyer acquires the goodwill, client list, management agreements, and staff contracts rather than the company itself.
Individual vs Corporate and PE-Backed Offers
When more than one buyer is interested, you will often find yourself comparing offers from fundamentally different buyer types. The comparison cannot be made on headline multiples alone.
Individual buyers — owner-managers acquiring a business to run themselves — typically offer a lower AMFI multiple than corporate buyers. That lower multiple reflects their personal funding capacity and risk tolerance. However, individual buyers almost always structure the consideration as 100% at completion with no earn-out. The economic simplicity of this structure has real value: you receive everything on day one, with no exposure to post-completion portfolio performance, no non-interference obligations, and no risk that an earn-out dispute arises two years later.
Corporate and PE-backed acquirers typically offer a higher headline multiple. But that headline is not what you receive at completion. A structure with a 65% completion payment and a 35% earn-out means that 35% of the “price” is conditional, deferred, and subject to post-completion risk. The buyer controls operational decisions after completion. Your earn-out depends on how well they manage the portfolio.
The right comparison is risk-adjusted expected value. Before comparing two offers, discount the earn-out portion of each corporate offer by your honest assessment of the probability that you will not receive it in full. A headline offer of £600,000 with a 35% earn-out produces a completion payment of £390,000 and a contingent £210,000. If there is a meaningful risk of shortfall — because the buyer’s operational track record is unproven, because the non-interference protections in the offer are weak, or because the earn-out period extends beyond the period of your own engagement in the business — the risk-adjusted value of that offer is lower than its headline.
This is not an argument against earn-outs. For the right buyer with robust protections, an earn-out can be appropriate and financially superior to an individual buyer’s offer. It is an argument for doing the comparison correctly.
Earn-Out Terms Worth Negotiating
The earn-out section of an offer is the area where sellers most commonly accept terms they should have challenged. Three elements deserve particular attention.
The AMFI definition. Buyers sometimes propose definitions that include deductions you should resist. Watch for management overhead allocations charged against the earn-out AMFI; exclusions for “gap properties” identified by the buyer as not meeting their management standards; and newly acquired portfolios merged into the earn-out scope without a corresponding baseline adjustment. Each of these deductions reduces the AMFI figure against which your earn-out is measured, without any change to the portfolio’s actual income.
Retention vs growth as the baseline. Whether the earn-out targets require you to retain the AMFI at completion or grow it is a critical distinction. A retention-based earn-out rewards you for maintaining what you sold. A growth-based earn-out requires you to generate new income after completion — from a business you no longer control — to receive the consideration agreed.
Collar protection. A collar provides a floor below which the earn-out cannot fall, regardless of AMFI performance. If the earn-out is £200,000 and the collar is set at £120,000, you are guaranteed at least £120,000 in deferred consideration even if the portfolio deteriorates. Collars are not always offered, but they can often be obtained by negotiation — particularly where your continued engagement post-completion is part of the buyer’s rationale for the headline price.

Headline vs What You Actually Receive
The gap between the headline offer and what arrives in your bank account is often larger than sellers anticipate.
Broker fees are typically charged at 1–3% of the agreed transaction value, payable at completion. On a £500,000 transaction, a 2% fee represents £10,000.
Legal costs for the seller’s solicitor typically run to £5,000–£15,000 for a transaction of this scale, depending on complexity, the number of branches, and whether due diligence queries require significant negotiation.
Capital Gains Tax and BADR. The net proceeds after deductions are the starting point for your CGT calculation. Business Asset Disposal Relief reduces the applicable CGT rate for qualifying disposals. The rate increased to 18% from April 2025 for most disposals; specialist advice before completion remains essential.
The earn-out right and Marren v Ingles. The right to receive future earn-out payments is itself a capital asset. Under the principle established in Marren v Ingles [1980] 54 TC 76, the estimated market value of that right is included in your disposal proceeds in the completion tax year — and CGT is charged on it — even though you have not yet received the cash. You may face a tax liability in the completion year on earn-out proceeds that will not arrive for twelve to twenty-four months, and that you may not receive in full at all. Agreeing a defensible valuation methodology for the earn-out right with your accountant before heads of terms are signed, and building the resulting CGT liability into your cash flow plan, is essential.
Exclusivity and Conditions
Exclusivity periods for letting agency transactions typically run four to eight weeks. The duration should reflect the genuine time required to complete due diligence and progress legal drafting — not a buyer’s preference to lock you out of the market longer than necessary. A shorter exclusivity period — four weeks rather than eight — is preferable for sellers, reducing exposure to the risk of the buyer failing a condition late in the process.
Common conditions include: satisfactory review of management agreement documentation; confirmation of acquisition financing; and formal board or investment committee approval. Each condition gives the buyer a legitimate exit route, and you should seek clarity before accepting exclusivity on what “satisfactory” means in each case and what triggers a condition as failed rather than outstanding.
Where a management agreement audit is a condition, the buyer will review your managed portfolio for documentation completeness, fee-rate accuracy, and compliance with current regulatory requirements. Conducting your own internal audit before the process begins is sound preparation and reduces the risk of a late-stage renegotiation based on documentation gaps.
How to Respond to an Offer
There are six main routes, which can be combined.
Accept where the terms are fair and the certainty of completion outweighs the marginal benefit of further negotiation.
Counter on the AMFI multiple, supported by your retention history, portfolio quality, and any comparable transaction evidence your broker can provide.
Counter on the earn-out proportion, seeking to increase the completion payment and reduce the deferred element — reducing your post-completion risk without necessarily changing the headline number.
Negotiate the AMFI definition to remove buyer-side deductions: request that management overhead allocations are excluded, that gap property exclusions apply only to an agreed list confirmed at completion, and that no newly acquired portfolios can be merged into the earn-out scope without a corresponding baseline revision.
Request a collar on the earn-out, establishing a minimum deferred payment regardless of AMFI outcome.
Negotiate the exclusivity duration — seek the shortest period consistent with the buyer completing due diligence in good faith, and resist open-ended extensions once exclusivity expires.
No response is irreversible at first exchange. A counter that a buyer initially rejects may be accepted after further negotiation; a collar refused at first offer may be conceded in return for movement on another term. Managing this sequence as a structured process — rather than a single-shot exchange — is where experienced advisers add material value.
