Frequently asked questions
- How much can I legally raise rent?
- It depends on your state and municipality. Many jurisdictions have no limit, but some (especially California, New York, Oregon) have rent control or rent stabilization laws capping annual increases, often at 3–8% or CPI + fixed percentage.
- How often should I raise rent?
- Annual increases of 3–5% are common and generally accepted by tenants when done consistently. Skipping increases for years and then making a large jump often triggers turnover. Small, frequent increases are usually better.
