Zoopla said the current plan was to continue the roll out to a further 72 locations across the UK.
The nine regions where the service has been trialled include Bath, Brighton, Cardiff, Chester, Exeter, Nottingham, Tunbridge Wells and parts of London.
Each report offers vendors local insights relating to their home including average time to sell, price changes over time and Zoopla search data.
The reports can be downloaded by Zoopla agents via ZooplaPro and are co-branded at branch level.
It said the reports had helped reduce uncertainty and ambiguity for sellers and had been effective for estate agents in prospecting and winning instructions.
Home owners not using a Zoopla agent that wish to buy the reports independently can do so directly from Hometrack for a fee of £19.95.
The report is created using Hometrack’s automated valuation model covering capital valuations, confidence range, and rental and yield estimates for 13 of the top 15 mortgage lenders in the UK.
Charlie Bryant, managing director of Zoopla’s property division, said the latest property valuation report will enable agents to demonstrate their local expertise with accurate, reliable and independent data.
