The importance of the key listings portals isn’t in doubt, but their continued dominance may be, says Lisa Isaacs.

Free-to-list platform Residential People is 14 months old and has 1,800 listing agents but says it now wants to turn into a mutual-style property portal.

Residential People and OneDome are both offering existing and new estate agency customers services as part of their platforms.

Residential People now lists 30,000 sales and rental properties in the UK and has promised never to charge agents to list on its platform.

The Negotiator tracks down the portal's co-founder to find out how it's going to become the world's 'Rightmove'.

The Negotiator talks to Christopher May, Founder and Director of the property portal where you can advertise your property listings online for free – and reduce overheads.

Ambitious aims of Residential People appear to be coming to be bearing fruit, helped by offering free sales and lettings listings to agents.

Residential People debuts with 1,490 houses, 203 flats and two developments in the UK.
