The peak time to sign a lease is between May and September. The national average monthly rent for a one-bedroom apartment is $1,536, 0.8% higher than last year. Renters may face varying price increases depending on the landlord. Rent control laws differ by state and city. To reduce rent hikes, consider renting from smaller landlords and inquire about additional fees. Signing a lease that specifies notice before a rent increase can help tenants plan ahead. Landlords should weigh the long-term benefits of retaining good tenants over short-term financial gains.
