When should I raise rents across a portfolio?
Quick answer
Raise rents when the gap between your rents and the current market has grown, your costs have climbed, and each lease reaches renewal. Do it per unit on its own renewal date, not all at once. Anchor every increase to comparable local rents, keep it moderate to protect good tenants, and stagger increases across the calendar to smooth your cash flow.
Start with the market, not a flat percentage
The right increase starts with what comparable units actually rent for today, not a number you pick out of habit. Pull recent listings for similar bedrooms, condition, and neighborhood. If your rents sit well below that, you have room; if they are already at market, push gently or hold.
A portfolio rarely moves as one. A unit in a hot submarket may support a real bump while another across town is already priced correctly. Price each property against its own local comps rather than applying a single flat percentage everywhere.
Time increases to each lease, not the calendar year
Rent increases belong to lease renewals, not to one date on your calendar. Raising every tenant at once builds a wall of turnover risk and dumps a month of work on you. Instead, adjust each unit as its own lease comes up for renewal.
Staggering renewals across the year smooths cash flow and spreads any vacancy risk. It also gives you time to handle each conversation well. Send renewal offers early, so a tenant who declines still leaves you runway to re-list.
Weigh turnover cost against the increase
A moderate increase on a reliable tenant usually beats a steep one that pushes them out the door. Turnover gets costly once you count vacancy, cleaning, marketing, and make-ready work. Weigh the extra rent against the real cost of losing a proven tenant.
- For strong, long-term tenants, keep increases modest and predictable.
- For units far below market, close the gap over two renewals instead of one shock.
- For chronic late-payers, let the market rate stand and prepare to re-list.
Follow notice rules and stay consistent
Notice periods, increase caps, and rules on frequency vary by state and sometimes by city. Some places limit how much or how often you can raise rent; others barely regulate it. Rules vary, so check the state guides at the state law guides and confirm with local counsel before you send a notice.
Whatever the local rule, apply your logic consistently across tenants to stay clear of fair housing trouble. Document how you set each new rent, so every increase traces back to market data rather than to who happened to ask.
How Rentari helps
Rentari keeps a portfolio of renewals from turning into chaos. Messaging and Renewals tracks every lease term and runs the renewal conversation per unit, so increases follow each tenant's own date instead of one stressful month. When a tenant accepts, E-Sign and Leases turns the new rate into a signed lease with a court-ready audit trail.
To decide the actual number, Tax-Ready Reporting and Auto-Accounting show what each unit earns against its costs, so you can see which properties are underpriced and which are carrying the rest. You raise rents on evidence, not guesswork.
