HMO Valuations (3)

HMO Valuations can be a bit complicated. We’ve put together this guide/article to help HMO property developers and investors through the process from start to finish, allowing them to make the best decisions. Most of the information in this article relates to re-mortgage valuations but also touches on sales valuations, which bizarrely can differ.

Purpose of HMO Valuation

Depending on your objective (mortgage or sale) as an investor or landlord will dictate the purpose of your inquiry about the potential value of your HMO property.

For mortgage/remortgage

This is about trying to get to the bottom of what a surveyor will come up with, which is no easy task, as the surveyors all tend to have different opinions. 

Summary; speak to a local surveyor, who is likely to be doing the valuation for your mortgage/remortgage.

Note: Surveyors are generally negative by nature and generally need help. This is due to this representing only a small fraction of their valuation workload. HMO mortgage brokers are not in the game of predicting the valuation. Good ones like, are experts in managing the process and helping find relevant lenders who are happy with commercial valuations. They cannot predict the final value.

HMO Valuation

Summary: speak to an HMO-specific sales agent ( to understand investor sentiment currently in any given area of the UK. Most investors buy based on yield. The better the area the lower the gross yield, for example, Mayfair is circa 2% (not that anyone does HMOs as an investment strategy in Mayfair).

Note: do not expect an exact figure from a potential agent, a good one will give you a range. Their job is not to guess the sale value, but rather extract the maximum potential £ from an HMO property sale available from the market at any given time

HMO Valuation Methods

There are 2 types of valuations when it comes to HMOs. Brick & mortar, and commercial.

Brick & Mortar HMO Valuation

Brick & 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.

Brick and mortar valuations are reached by a set of standard criteria to which 99% of 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 brick 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
  • Condition
  • Management

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 (15-35% 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(15-35%)) *12 / Yield 


HMO Property Value = Annual Net Rent / Yield
