If you are looking to buy a house, assessing the value of property is one of the central tasks you will have to perform. Home buyers need to decide whether the price of a property reflects the current market price and whether it would be a profitable investment. The price you offer a seller for his house should be based on the results of this assessment.
A good valuation, however, is not your estate agent telling you the Smiths down the road are trying to sell their home far above value and that you should better keep your hands off it. Appraising the value of a property is a complex issue where many factors have to be taken into account – it is a combination of art and science.
Independent property valuations are only performed by chartered surveyors. It is a common misconception that Estate Agents value property for home sellers. Agents simply guide them to a suggested asking price – they cannot be relied upon to provide objective and accurate valuations.
The asking price an Estate Agent recommends is often over-inflated because of their desire to appease the seller in order to win an instruction. On the other hand Estate Agents may encourage a seller to accept a below-market offer in order to secure a quick sale (a high turnover is much more profitable for an agent than a small increase in the selling price). Since you cannot be sure about the Estate Agent’s motivation and whether the price is above or below market value, it is recommended that you perform an independent valuation.
It is perfectly possible for non-professionals to do their own valuations.
Unfortunately, a thorough understanding of valuation theory and methodology is not commonplace. There has been little comprehensive literature available as to what constitutes value and what the different methods of determining the worth of a property are. The following article will provide some insight into theoretical approaches to value and valuation methodology.
There are two main theoretical approaches to determining the value of a house, namely the “Comparable Sales Method” and the “Income Approach”. A third method, the “Cost Approach”, will be discussed briefly, but since it is not an autonomous approach, emphasis will be put on the first two methods. The first valuation method focuses on actual market data, whereas the second calculates the profitability of the investment. Since the two approaches complement each other, a diligent valuation will always have to use both.
Value is, of course, a subjective rather than an objective term. If you favor a detached house with garden somewhere in the Cornish countryside, a two-bedroom apartment in central London is of little value to you. Even small features like the size of windows are worth more or less to different people. The forces influencing the value of property include the property features and its location, social institutions in the area, wage levels, tax codes, and also building zones and environmental legislation. It does make a difference whether a flat is in Sheffield or Swindon, whether the next good school is two or ten miles away, and whether it is a 12 th floor flat with view of St. Paul’s or a basement flat in Hackney.
The appraisal methods discussed below are theoretical approaches to the question of value and help you estimate the worth of a property in accordance with your preferences and needs. In practice, however, it is the free market, i.e. the forces of supply and demand, which decide what amount of money a house changes hands for.
There may be a substantial gap between subjective valuations and the fluctuations of the free market. Thus, the subjective value of a property does not always correspond to its actual price. The forces of supply and demand cannot be scientifically predicted. Every property valuation can only ever be a guideline to what the house will eventually change hands for.
The “Comparable Sales Method” is also called “Inferred Analysis” of property value. This method estimates the value of a house by comparing it to the prices of like-kind property sold in similar locations within a recent period of time. The basic assumption is therefore that a property is worth what it will sell for, in the absence of undue stress and if reasonable time is given.
This method concerns the actual market value of homes by examining factual data. It is the most prevalent method in the residential property market and works with general trends and projections.
Date of transaction, means of payment, transaction speed, etc.
Size, location, conditions, utility, building regulations, business climate, etc.
|Transaction Details||Asset Characteristics|
|Address||Price Paid||Date||Payment Method
An ideal database will contain information relating to transaction date, price paid, property features and size etc.
A large database is held by the Land Registry. It contains transaction date, price paid, and information about the general property type. Companies wishing to use this data can purchase this in bulk directly from Land Registry. The general public is best placed however to use a free service such as the one below.
Information on specific transactions is available to the public for free through a website called Mouseprice.com. Use this site for raw data on house prices from the Land Registry database.
Estate Agents’ own internal databases record what they have sold, at what price. Unfortunately, there is no central repository for this information. Thus, their data usually concerns only a small proportion of total sales in a particular area. Estate Agents are not always happy to provide complete information and cannot be relied upon for an official valuation. The benefits can be that where available, this data contains rich descriptive information.
+ It is the most straightforward method and general practice, especially in the residential housing market
+ As a theoretical approach it most closely reflects the actual market value of a property, therefore its objective value
– Sometimes it might be difficult to locate enough similar, recently sold properties
– 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 entail that it is a reasonable price for an individual, both to sell or to buy.
Example : I might want to purchase a property in order to let it. The property’s price might be within a reasonable market price range, but because average rents in the area are not very high the investment would not be profitable to me.
The “Income Approach” is also termed the fundamental or intrinsic method of property valuation. In this method, the present worth of a property is estimated on the grounds of projected future net income (in rent, for example) and resale value. Using this technique, a buyer can estimate whether a certain property would be a profitable investment.
The method uses the discounted cash flow (DCF) model to determine the present value of an investment. One underlying assumption of this approach is the principle of opportunity cost of capital, i.e. that money is of more value to its holder today than in the future.
Although complex, this method is essential to any property valuation, especially for buy-to-let investments. It is frequently being employed by financial and investment professionals when valuing assets.
Example : I want to buy a three-bedroom flat and rent it out. Historical data shows that I can expect a 50% increase in market value within 10 years. Market analysis tells me that the average rent of comparable properties in a similar location is £4000 per annum.
Example : A 3-bedroom flat costs £120,000. I expect to be able to sell it for £180,000 in 10 years. I set my discount rate at 8%.
The calculation looks like this:
PV = £180,000 / (1 + 0.08)¹º = £83,375
Example : The three-bedroom flat generating £4,000 per year in rent costs £1,600 in expenses. That means I have an annual income of £2,400. I set my discount rate at 8%. The calculation for the net present value of the first year’s income is:
PV = £2,400 / (1+0.08) 1.
It results that the present value of my net income in year 1 is £2,222.
Yet, I do not plan to resell my flat after one year, but keep it for at least 10 years. In that case the calculation goes as follows:
PV = (£2,400 / 1.08) + (£2,400 / 1.08²) + (£2,400 / 1.08³) + … + (£2,400 / 1.08¹º) =
= £2,222 + £2,058 + £1,905 + £1,764 + £1,633 + £1,512 + £1,400 + £1,296 + + £1,200 + £1,112 = £16,102
The results, based on our assumptions, show that the present-day value of the three-bedroom flat is
£83,375 + £16,102 = £ 99,477
I would therefore be ill-advised to buy the flat at the current price of £120,000.
+ Focuses directly on the value of the property to the individual concerned
+ Income analyses are very detailed and derive specific conclusions (in contrast to the more general approach practiced in the sales-comparison method)
– This method is more complex and less intuitive than the comparable sales method. This is one of the reasons why it is often overlooked.
– Ignores the actual market prices for property by neglecting the comparable sales analysis
The cost approach estimates the replacement value of property by analyzing the cost component of the specific land and building. It lies somewhere between the inferred and the intrinsic method, and is not a fully autonomous valuation method.
Value is calculated by adding the free market value of the land as if vacant to the reconstruction cost of the building, minus depreciation suffered over the years in comparison to a new building.
Market value of land: £100,000
Replacement cost of the building: £500,000
Value of property: £525,000
+ Sets the value at the actual cost or price of the property
– Relies upon other valuation methods to derive the value of the land
– Neglects the difference between cost and value, namely that one property might be cheaper than another but generate a much higher net income
The “ Comparable Sales Method” focuses on market data of sales of similar property in a recent time period and thus gives and estimate of which price is adequate for a certain kind of property. Sales comparisons can easily be performed using internet databases of property transactions. The advantage of this method is that it reflects the actual market prices, but it neglects the aspect whether a property investment is profitable for seller and buyer, or not.
The “ Income Approach” concentrates on the profitability of a property investment. It analyses the present worth of projected future net income and anticipated future resale value. This method gives a good appraisal of whether a certain property is worth its price to the buyer, but it neglects the relation to the overall market.
The “ Cost Approach” lies somewhere between the two previous methods and is not actually an autonomous method of value analysis. It estimates property value by adding the cost of the land to the replacement cost of the building minus depreciation, thus coming up with a figure of how much the property should be worth. But it neglects far too many factors to be a useful method of valuation.
In order to get a good estimate of value for a property it is necessary to employ both the sales-comparison and the income approach.
It should be clear by now that there is no perfect method of assessing the value of a property – an appraisal is an art as much as a science, and in the end it is supply and demand which determine the actual price of a house.
Yet at the same time, the methods discussed above provide guidelines for home buyers on how to estimate the approximate worth of a house. By performing an independent valuation, you will be able to assess whether the property you are looking at is over- or under-valued and whether the investment is profitable for you. It is generally recommended that you do not buy a property without first doing a thorough valuation. In order to get a reliable and accurate estimate of value, you will have to use both the sales-comparison and the income method of valuation.
