Understanding Rent Increases

CPI-Based Increases

Many landlords tie annual rent increases to the Consumer Price Index (CPI), which measures inflation. This ensures rent keeps pace with the cost of living and property expenses while remaining fair and predictable for tenants.

The CPI is published by the Bureau of Labor Statistics and varies by region and time period. Common practice is to use the regional CPI for the previous 12 months.

Custom Percentage Increases

You can also use a custom percentage increase based on market conditions, property improvements, or other factors. Be sure to check local rent control laws and lease terms before implementing any rent increase.

Legal Considerations

  • Notice Requirements: Most jurisdictions require 30-90 days written notice before a rent increase takes effect.
  • Rent Control: Some areas have rent control laws that limit the amount or frequency of rent increases.
  • Lease Terms: Review the lease to ensure rent increases are permitted and follow any specified procedures.
  • Fair Housing: Rent increases must be applied consistently and cannot discriminate based on protected classes.

Best Practices

  • Market Research: Compare your proposed rent to similar properties in your area.
  • Communication: Notify tenants well in advance and explain the reason for the increase.
  • Timing: Consider implementing increases at lease renewal rather than mid-lease.
  • Reasonableness: Moderate, predictable increases help maintain good tenant relationships and reduce turnover.
  • Documentation: Keep records of all rent increase notices and tenant communications.
