House Price Obsession

Frequently Asked Questions


When are the January 2018 house sales released?

28th February.


Why isn't a house price listed for a sale that I believe took place?

The Land Registry excludes the following types of sales:

  • Part or a share of a property
  • Right-to-buy properties - properties that have been sold by local authorities to the public
  • Transfers following divorce or by way of gift or exchange
  • Compulsory Purchase Orders
  • Court Orders relating to relationship separation, and repossessions as a result of falling into debt, or for some other reason
  • Transfer of more than one property as part of a portfolio
  • First registration of leases for 7 years or less
  • Additional price paid transactions valued below £100

How are current price estimates calculated?

Revealed due to public demand... Our estimates are calculated using the sold price in conjunction with the Land Registry Price Index for the local authority/county for the address, and we estimate to the current month (November 2019).

The primary variable in our estimates is the sold price. A side effect of this however, is that a sold price that was made at below market-value (i.e. where the buyer underpays for a property) will result in a lower estimate relative to current market value. Conversely, a sold price that was above market-value will most likely result in a higher estimate.

Estimate equation:

current price estimate = sold price * Land Registry Index percentage change

Where the Land Registry Index percentage change is the percentage change between the index value at sold date and the current index value.

What's the difference between 'Price Change' and Yearly Change'?

The 'Price Change' is the absolute price change between the the price paid for a property, and the previous price paid.

The 'Yearly Change' is the average yearly change in price between the price paid for a property and the previous price paid.


What's the difference between 'Annual PGR' and 'Compound AGR'?

The 'Annual Percentage Growth Rate' is the percentage change between the purchase price and sale price, divided by the number of years.
The annual percentage growth rate is the straight-Line growth rate and unlike CAGR, does not take into account compounding. This is similar to the Average Annual Return (AAR) used in finance.

The 'Compound Annual Growth Rate (CAGR)' is the mean annual growth rate of an investment over a specified period of time longer than one year.
The CAGR is not a true return rate but a figure describing the rate of change as if it had changed at a steady rate over the period.
