HMO Valuation specialists
We specialise in HMO valuations across Article 4 and non-Article 4 areas, working with investors, lenders and developers across London.
Getting the methodology right is everything. Give us a call.
Houses in multiple occupation require a specialist approach to valuation. Unlike standard residential property, an HMO's value is determined primarily by its income-generating potential, its licensing status and, critically, whether it requires planning permission to operate as an HMO. Getting the methodology right matters — an incorrect approach can result in a valuation that lenders will not accept.
Our RICS-registered valuers specialise in HMO valuations across both Article 4 and non-Article 4 areas, and work with investors, lenders and developers across London and the wider UK.
Our Valuation Methodology
The correct approach to valuing an HMO depends on its planning status. Select yours below to understand how we approach the valuation.
In Article 4 areas, or where a property has more than six rooms, planning permission is required to operate as an HMO. These properties are valued using an income approach, reflecting the income stream the property generates as a commercial asset.
Income and Yield Approach
We assess the gross rental income generated by the property and apply an appropriate yield, reflecting the HMO's income-generating potential as the primary driver of value.
Operational Cost Adjustment
HMOs carry higher operational costs than standard lets. We apply a gross-to-net adjustment of approximately 25% to reflect management fees, licensing costs, maintenance and void periods.
Planning Status Verified
We verify the property's planning status and licensing position before valuing, ensuring the approach adopted is appropriate for the specific property and local authority area.
Lender Accepted Reports
Our valuations are prepared to RICS Red Book standards and accepted by specialist HMO lenders, ensuring the report supports your finance application.
In non-Article 4 areas, HMOs with six or fewer rooms do not require planning permission. For these properties we adopt a cost-plus approach, which reflects the residential value of the property with an uplift for the conversion works carried out.
Comparable House Value
We establish the market value of a comparable standard house in the same location, providing the base from which the HMO premium is calculated.
Conversion Cost Premium
We assess the cost of the conversion works carried out to create the HMO and add this as a premium to the comparable house value, reflecting the additional investment made.
Local Market Analysis
We analyse local comparable evidence to sense-check the cost-plus figure and ensure the valuation reflects what a willing buyer would actually pay in the open market.
Lender Accepted Reports
Our reports are prepared to RICS Red Book standards and accepted by specialist HMO lenders, giving you confidence the valuation will support your lending requirements.
