How surveyors determine property value: Understand your property valuation

Property Value calculation

Do you know what your property worth? As an investor, you need to make sure you know what value of your property is.  The best way to do this is to view value in the same way that a property valuer would determine property value.  This article examines how surveyors determine property value.

Online property value calculators

There are numerous online property portals where you can simply enter your postcode and some basic details about your property and it will give you an estimate of the price of your property. These online calculators are of course useful for providing a rough estimate of price. But when it comes to banks lending money for mortgages, they will appoint a valuer, regulated by the RICS to provide a valuation of your property. So how do these valuers determine price and how to they come up with your property valuation?

Now obviously, property valuers such as those regulated by the RICS spend years studying and have rigours exams to pass, so you’re not going to get the same level of knowledge by reading one short article.  However, you can learn about their approaches and how they work and we’ve covered this at a very high level in this article.

How surveyors determine property value: the three approaches

  1. Sales Comparison Approach – this is the most common method. A valuer will determine a property value based on recent selling prices of similar properties in the same location
  2. Income Approach – estimates the property value based on the income which it generates
  3. Cost Approach – property value is determined to be the cost of a building an equivalent property considering the costs of the land and construction expenses, less depreciation.  This approach only has merit in certain scenarios such as for an insurance valuation .

You are not going to be able to work out the property value without doing some homework. The most challenging thing for everyone working in the real estate market is access to transparent market data. 

Without transaction data, you will not be able to come up with an accurate view of the price. Remember there is a difference between the asking price and purchase price.   

You will need to collect some data on what prices houses have sold for, whilst property portals are good to see what prices properties are selling for and get an idea of the market. They are not so useful to undertake detailed analysis about what property has actually sold for, there are many data services for this. Some simple internet research will help, together with people active in the market, such as property agents, your property manager (if you have one), accountants and lawyers.

Sales Data

You will need to collect some sales data on between 5 – 10 transactions for similar properties, these should be:

  • In the same location
  • Have the same or similar physical aspects
  • Have been sold in the past 12 months

Market Trends

You will need to have a sense of what is going on in the property market, so you will want to get an understanding of the following information:

  • At what point in the real estate market cycle are you at?
  • Is the market active?
  • How hard is it for buyers to obtain mortgages? And on what rates?
  • Are there any specific incentives for buyers?

Rental Data

You will need to collect rental comparison data again for similar properties, these should have the same number of bedrooms and have been let in the past 3 months.

You will also want to have a look at real estate market portals to determine what other rental competition is out there and how much is it available for? The point of having this data, although it may not be comparable, is it will set a rental ceiling for your property, as no one is going to pay more for your property than other similar properties if there is a lot available.

Yields

It is important for you to understand what yields are being achieved in the market. This will give you an understanding of the rental levels and capital values which are being achieved.  Now you’ve collected the data, we can return the different methods that surveyors use to determine value.

1. The Sales Comparison Method

The comparable sales method is the most prevalent method in the residential property market. This estimates the property value by comparing it to the prices which similar properties have sold for.

The process for using comparable sales can be highly subjective and requires the following:

  1. Systematically assembly of data on comparable properties. The factors impacting value then have to be weighed against each other. The relevant elements can be split into various characteristics:
    • Transactions Characteristics – such as date of transaction and means of payment
    • Physical characteristics – size, location, condition, etc
  2. Once the data has been obtained and collated the task is to draw informed conclusions on the value of your property – for example, a valuation price range – based on the evidence collected. Those properties that are most similar to yours should receive a greater weighting than those which are less comparable.

Comparable Sales Method Disadvantages

Sometimes it might be difficult to locate enough similar property transactions to draw meaningful conclusions with regards to what the value should be.

Market value and price might differ due to “unreasonable” actions by other actors. This technique makes no reference to intrinsic value. If a property’s price is reasonable on a comparable basis, it does not necessarily follow that this is a reasonable buying or selling price for an individual. A minimum of three comparables must be reported in the sales comparison approach.

2. The Income Approach

There are several ways to arrive at a property value considering its income; some of the most common are:

  • Discounted Cashflow (DCF) – Makes assumptions as to the income generated by the property and its resale value. The annual rental returns are then ascertained and those future cash flows are discounted back to a present value.   This is a reasonably complex process.
  • Capitalisation method – estimates the value of a property based on the income it generates. The capitalization rate (cap rate) of a real estate investment is calculated by dividing the property’s net operating income (NOI) by the current market value.
  • Income in Perpetuity – calculated by dividing the gross rental income by gross yields

There are advantages and disadvantages in using, the different methods. For most people running a DCF it can be a reasonably complex process. This is because you will need to make a number of assumptions, such as rental growth rates, vacancy rates, costs as well as determining an appropriate discount rate. Unless you are selling a complex investment such as a block of apartments it is probably not appropriate.

In reality, you will be able to use the income in perpetuity model because you will most likely be able to find the best quality information to determine value. And this is more important to your analysis than having a highly complex model – you can develop a highly complex DCF model but the reality is if the inputs you put into the model are incorrect your out put price will be wrong.

3. The Cost Approach

With the cost approach to valuation, the property value is determined to be the cost of a building an equivalent property considering the costs of the land and construction expenses, less depreciation. 

This approach only has merit in certain scenarios such as for an insurance valuation. It is typically considered to be less reliable and in addition, it requires information which is very difficult to obtain.

Conclusion

As an investor, you need to make sure you know what the price is. Sure, you can use one of the many online calculators or tools, but the best way for smart investors to behave is to work out their view value in the same way a property valuer would determine property value.

The comparable sales method is the most prevalent method used in the residential property market, estimating the value of a house by comparing it to the prices for which similar properties have sold.

Importantly, there is no absolute truth when determining the price for real estate, because the real estate market is not a perfect market. So, you will not and should not arrive at an absolute price, this would not be a realistic number – you are likely to fall within a range of values.
