First, always remember that algorithms, as most rate estimates are, are always backward looking. They are based off the past few months of sales / rentals. Especially in the rental market that can be a major issue as things change quickly, and often. The market is booming in June for example, but often very slow in July. Early December is busy, then things screech to a halt. Prices based off the prior 2 months are usually about 10% too high once a seasonal shift sets in. Our method is to view Zillow and Realtor.com maps to find nearby homes similar in size, condition, and yard / lot features. We make experienced adjustments from there and also cross reference with our own extensive internal rental data to nail down an algorithm like price. From there we make two major adjustments depending on what time of year we'll be listing the home. One is for general seasonal swings, and one is for the response the comparison homes seem to be receiving. If they're not getting inquires, they are unlikely to rent at those rates, unless the season shifts higher as we see in the spring and late fall. https://www.zillow.com/rental-manager/price-my-rental/ https://rental.turbotenant.com/rent-estimate-report https://www.rentometer.com/
