Rental prices for Las Vegas houses are climbing at the second-fastest rate in the U.S. CoreLogic reported that rents were up 5.7% year-over-year in July in Las Vegas, compared to 3% nationally. Orlando, Florida, led the pack at 6.4%. Investors bought cheap homes in bulk to turn into rentals after the market crashed. Despite Las Vegas' fast-rising sales prices, landlords are holding on to their properties amid strong demand from tenants.
