Renters are getting more perks as increased construction adds to housing market supply

• Zillow said 30% of rental listings offer some sort of concession to prospective renters.
• That's up from 24% a year ago as a construction boom is giving tenants more options.
• The greater prevalence of concessions may be a signal that rent growth is about to level off, Zillow said.

More rental listings are offering sweetened deals, as an influx in freshly constructed properties gives prospective tenants more options.

Zillow said 30% of rental listings now offer at least one concession, up from 24% a year ago. They include perks like free months of rent or parking.
