The amount of a security deposit can vary widely depending on the state and the rental property itself. Generally, landlords may charge up to one to two months’ rent for a security deposit. However, some states have no limit on the amount a landlord can charge, while others specify maximum amounts. For example, in Alaska, the maximum security deposit is two months’ rent, except for units renting for more than $2,000 a month, which have no limit. It’s important to check the specific laws in your state for the most accurate information.
