LSL Property Services has started a £10m share buyback programme that will run until June 30 this year.
The group - which includes the Reeds Rains and Your Move brands - will purchase up to a maximum of 10,515,895 ordinary shares, in a move approved by its shareholders last year.
Numis Securities Limited has been appointed to carry out the non-discretionary share buyback which starts immediately and repurchased shares will held in treasury.

Shareholders will asked to vote on the continuation of the buyback programme at LSL's upcoming annual general meeting on May 27.
In March, LSL - which provides financial services, surveying and valuation and estate agency services - reported record underlying operating profits.
Investors were told underlying operating profits increased to £49.3m, up 40% from £35.2m in 2021, on group revenue of £326.8m, up from £266.7m.
The firm said a growth strategy designed to increase its financial services offering would protect it in the face of a more challenging housing market to come - pointing to estimates that suggest the mortgage market will be about 11% lower than in 2021 and housing transactions about 19% lower.
