HMO Valuation Methods

Bricks & Mortar HMO Valuation

Bricks & Mortar or Buildings Valuations are the most common type of HMO Valuations. They are commonplace is the property is a normal single (C3) dwelling and is based on the current fair market value and local comparables.

This type of HMO, when viewed through the eyes of a surveyor, is a residential property that happens to be rented out on a multi-occupancy basis.

Bricks and mortar valuations are reached by a set of standard criteria to which 99% surveyors work. 

These include:

  • Size – bedrooms & square footage
  • Condition
  • Comparable properties recently marketed and sold

Commercial (Investment or Yield) HMO Valuation

This HMO Valuation method is offered by certain lenders who offer commercial or yield based HMO valuations subject to certain criteria. It’s not an exact science to figure it out but it’s not black magic either.

The main reason for seeking this type of valuation is that typically a commercial valuation will be higher than a bricks and mortar valuation. As such an investor will have the ability to release more capital during a refinance, and/or have a lower loan to value ratio which could result in better HMO mortgage interest rates.

Factors Affecting HMO Valuation Method

There are no hard and fast rules, and again it can be subjective based on the lender’s criteria, what side of the bed the surveyor got out of, and other variables including but not limited to:

  • Planning Permission Use Class C3, C4 or Sui Generis
  • Lender Selected
  • Surveyor Chosen
  • Location

If you’ve bought a commercial property (e.g. an office or retail space), gained full HMO planning consent, and converted it to a purpose built 12 bedroom house of multiple occupancy, then you’re argument for a commercial or yield based valuation is strong.

If you own a 5 bedroom house on a street full of 5 bedroomed houses, but you’ve rented the rooms out individually, the argument for a commercial valuation whilst not impossible, will be more difficult to make.

Factors Affecting HMO Valuation Yield

Available Comparable Properties
Planning Permission Use Class C3, C4 or Sui Generis
Property Size or No of Bedrooms or Units
Presence of an Article 4 Directive
Local HMO Density
Proximity to Local Amenities

Commercial HMO Valuation Calculation Model

There are a lot of myths surrounding this methodology, but having seen 100s of HMO valuations there is no magic surrounding it; it’s mathematical.
The only variables are;

  1. Rent
  2. Operating Costs (10-30% depending on the quality of property)
  3. Yield

Yield is normally the variable at the surveyors’ discretion and subject to factors affecting the valuation as mentioned in the paragraph above.

Some investors talk about using a “rent multiplier” between 8 and 12 times annual gross rent, but if you look into any valuation more closely it’s normally a function of the following formula or calculation.

Commercial HMO Valuation Calculation

HMO Property Value = (Gross Monthly Rent – Reasonable Operating Costs(15-30%)) *12 / Yield 


HMO Property Value = Annual Net Rent / Yield
