Many incentives are for first time buyers, or single home buyers. Taxes depend on region, but everywhere I see treats primary homes, secondary homes, and rentals as different classes of real estate. Now that doesn't mean the incentives aren't skewed. But I don't think landlords buying their 20th house are getting the same benefits as a first time buyer.
