When a home is renovated, the price that a buyer is prepared to pay will increase.
It is important to note, some home improvements will increase the value of the property by more than the amount they cost.
A good quality kitchen and bathroom are highly likely to add value to your home; however, building that new swimming pool in the garden that you've always wanted may not increase your sale price and may actually make it sell for less.
Our automated property valuations use a combination of historical sale data, property price indexes and recent sales in the surrounding area to calculate what a property is worth today.
Tell us about any home improvements so we can factor these into the property's valuation.
We've calculated the average price paid for property here. Using this, we can see the general price trend over time (which helps work out today's valuation).
The green line shows the average price paid for terraced houses located in postcodes starting with SW3 2.
In addition to this, we also show the lowest price and the highest price paid for property here (we remove extreme outliers like garages and castles as they distort the data).
Our automated property valuations work using the property's sale history along with recent sale data in the same road and surrounding area to work out how the price has changed over time.
Sometimes though, automated property valuations don't generate prices that are in line with current market conditions.
For example, if a property has previously been sold for less than its market value at that time (i.e. a distressed sale), this can lead to its current valuation being lower than it is really worth. An example of this is when a bank forces a sale through when a person is unable to pay their mortgage.
Create valuation reportIf the bathroom has recently been renovated, the house is more likely to sell for more money.
Our price adjustments are relative to the cost of the property, for example, for a two bed flat in Brixton, a high end bathroom may cost £6k to £8k. However, in a substantial 5 bed home in Holland Park, a bath alone could cost £20k upwards and the total cost of a refurbishing a bathroom may be well in excess of £50k.
So to justify a top quality bathroom install in a 2 bed flat, you may need to spend £6k plus (installing a towel rail, power shower, underfloor heating, extractor fan etc.) but to justify having the full increase in value for a top end bathroom in a £10m home in Kensington Park Gardens we'd expect you to have spent between £50k and £100k with a custom built bath tub amongst other bespoke products.
The more detail you give us about the property and the home improvements have been made, the more accurately we can tell you what it is worth.
