There's disappointment a Bill that would have regulated property managers more has been withdrawn.

Housing Minister Chris Bishop has scrapped the Property Managers bill, saying the cost-benefit was marginal at best.

He says it would have cost tenants and landlords.

Real Estate Institute CEO Jen Baird says the figures involved were small.

"Some of the numbers that I've seen have been 43 cents per property per week, up to about $2.50 per property per week."
