Frequently Asked Questions

How much can I raise rent?
In most US states, landlords can raise rent to whatever the market will bear, provided proper notice is given (usually 30–60 days). Some cities and states have rent control or rent stabilisation laws that cap increases — always check local regulations before raising rent on an existing tenant.
How often should I raise rent?
Most landlords review rent annually at lease renewal. Raising rent in line with local inflation and market rates (typically 3–5% per year) helps you stay competitive without shocking long-term tenants. Skipping increases for several years and then catching up in one jump tends to cause more turnover than gradual annual adjustments.
Is it better to raise rent or keep a good tenant?
Tenant turnover is expensive — typically 1–2 months of lost rent plus cleaning, repairs, and leasing costs. If your current tenant is reliable, a below-market rent increase that keeps them in place often nets more than maximising rent and risking a vacancy. The breakeven depends on your local vacancy rate and turnover costs.
