How do cash house buying companies determine the offer price for a property?

A cash house buying company usually sets its offer by estimating the property’s achievable resale value and deducting the costs, risks and return required to buy and sell it. The figure is therefore based on a financial appraisal rather than simply the asking prices of nearby homes. Two companies can reach different offers because they may use different resale assumptions, cost estimates and risk allowances.

1. Establishing a realistic resale value

The buyer will normally review recent comparable transactions, not just properties currently advertised. Completed sales are useful because they show what purchasers actually paid. The comparison may take account of the home’s size, layout, tenure, parking, outside space, condition and position within the neighbourhood. Asking prices can still provide context, but they do not prove that a property will sell at that level.

Valuation evidence may come from online data, local market knowledge, an independent valuation or a physical inspection. If the property is unusual, has limited comparable evidence or has been altered, the buyer may apply a greater margin of caution. A valuation is an estimate, not a guaranteed future sale price.

2. Working backwards from the expected sale

Once a likely resale figure has been estimated, the buyer may use a residual calculation. In simple terms, the expected sale proceeds are reduced by the costs of acquiring, holding, improving and reselling the property. The remaining amount forms the basis for the offer, subject to the buyer’s required return and its assessment of risk.

• Purchase-related costs, including legal work and property taxes that apply to the transaction.
• Surveying, valuation and other professional charges.
• Repairs, renovation, clearance, compliance work and contingency allowances.
• Finance or capital costs where relevant, together with insurance, utilities and other holding expenses.
• Resale costs, such as marketing, estate agency and legal fees.
• The possibility that the property takes longer to sell or achieves less than the initial estimate.

These deductions explain why a cash offer can be below an estate agent’s suggested marketing price. An estate agent’s valuation generally describes a potential open-market sale, while a buying company’s offer reflects what it believes it can justify paying after allowing for the complete transaction.

3. Assessing property-specific risk

The offer can change when legal or technical information raises uncertainty. Examples include a short lease, restrictive covenants, missing planning documents, absent building regulations approval, boundary disputes, tenancy issues, flooding history or unresolved ownership matters. The buyer may reduce the offer to reflect the cost and uncertainty of resolving these issues, or make the offer conditional on further investigation.

Physical defects are assessed in the same way. Structural movement, damp, roof problems, outdated services, Japanese knotweed, asbestos or extensive clearance work may require specialist reports and revised costings. A buyer may also allow for hidden defects because an initial viewing cannot reveal every problem. This does not necessarily mean the property cannot be bought; it means the risk is included in the calculation.

4. Considering the terms of the sale

Price is not the only variable. An offer may be influenced by the proposed completion date, whether the seller needs to remain in the property after completion, whether vacant possession is available and whether there are other parties in the transaction. A sale with straightforward title and possession may be valued differently from one involving tenants, probate administration or several legal owners.

Read the written offer carefully to establish whether it is fixed or subject to survey, title checks or other conditions. Some buyers may revise the price when new information appears. That is different from a figure confirmed after the relevant checks have been completed. The offer should also make clear whether any deductions are taken from the stated price or charged separately.

5. Comparing an offer properly

To understand whether an offer is reasonable, ask for an explanation of the valuation basis and the main deductions. Compare the proposed net amount with realistic open-market alternatives, taking account of estate agency fees, legal costs, mortgage interest, repairs and the time involved in marketing. A higher headline figure may not produce a higher net result if it depends on reductions, delays or substantial preparation.

Useful questions include:

• Which comparable sales or valuation evidence support the figure?
• What assumptions have been made about the property’s condition and resale value?
• Which repairs, professional costs and taxes have been deducted?
• Is the offer subject to a survey, title review or further negotiation?
• What could cause the price to change before exchange or completion?
• Are there any charges that the seller must pay separately?

A sound offer should be presented in writing with its assumptions and conditions explained clearly. The seller can then distinguish between the property’s estimated market value, the buyer’s purchase costs and the amount that would actually be received. Independent legal advice can help check the contract and identify deductions before any commitment is made.
