Homeowners interested in renting out their property can use Zillow's improved Rent Zestimate to get a good idea of what they could potentially earn in rent. The Rent Zestimate generates a property's expected rent income by considering a home's physical attributes and amenities, including square footage, number of bedrooms and bathrooms, and whether it has air conditioning, as well as public data such as the last sale price. For those looking to invest in or turn their home into a rental property, Zillow's new Rental Property Calculator is designed to help independent landlords determine if their prospective purchase makes financial sense. The calculator factors in property price, home appreciation forecasts, expected rental income, mortgage rates and more to find when the purchase will break even and begin to pay itself off.
