Having a rent roll is incredibly beneficial for landlords and property managers as it provides a detailed look at the current state of a property's tenant base and income flow. It is an easily navigable document that can be used to analyze an investment property, compare the average rents of a property’s units with comparables currently on the market, and make necessary adjustments to pricing. Rent rolls can also be used to analyze a potential investment, understand whether the gross rental income is likely to increase, decrease, or remain constant in the foreseeable future, and compare the rent roll with the income portion of the profit and loss statement (P&L) to ascertain if the gross income reported on the P&L is accurate. Buyers are able to determine more granular information like how long a tenant has occupied the home, which may help in the estimation of how likely they are to continue paying the rent.
