Wairarapa landlords have been warned by a real-estate expert to keep rent prices in check despite a thriving market or they may risk finding themselves "tenantless".
Trade Me statistics showed an 8 per cent increase in November rent prices - up from November 2013.
By region, the median asking price for a three to four bedroom home was $270 in Carterton, $275 in Masterton and $300 in South Wairarapa - a 20 per cent increase.
Property manager for LJ Hooker in Masterton, Chrissy Osborne, said there had been a surge in people looking to rent but landlords shouldn't be tempted to raise their prices too high.
"Most landlords are hoping to continue raising rental prices because rates and maintenance costs are going up. My advice to them is not to hike it up too much because otherwise they will price themselves out of the market then their houses will sit there untenanted.
