How Much Should I Raise Rent at Lease Renewal? A Small Landlord's Decision Framework

If you own one to five rentals and manage them yourself, you already know the renewal season knot in your stomach. The lease is up in 60 days, your tenant has been fine, and now you have to answer one uncomfortable question: how much do I raise the rent?

Go too low and you leave hundreds — sometimes thousands — of dollars on the table over the next year. Go too high and you risk a turnover that wipes out years of "gains" in a single vacant month. For a self-managing landlord without a property manager crunching comps, that decision usually comes down to a gut feeling. It shouldn't.

Why the "just do 3%" rule fails small landlords

You've probably read the advice to bump rent a flat 3% every year. It's simple, but it ignores everything that actually matters on your specific unit:

• Your local market moved differently than the national average. A 3% bump in a market that jumped 9% means you're falling further behind every year.

• Your tenant's quality has a dollar value. A tenant who pays on time, reports issues early, and never calls at 2am is worth keeping — even at a slight discount to market.

• Turnover costs are brutal and front-loaded. One vacant month, plus turn costs (paint, cleaning, listing, screening), can easily exceed $2,000–$3,000 on a single-family rental. That's often 4–6 months of the rent increase you were chasing.

The real math: increase vs. vacancy risk

Here's the framework experienced small landlords actually use. Start with three numbers:

• Current rent vs. market rent. What would this unit rent for today if it were empty? That gap is your maximum theoretical increase.

• Annual upside of the increase. A $75/month bump is $900 over the year — sounds great until you compare it to step 3.

• Cost of losing the tenant. Vacancy weeks + turn costs + new-tenant risk. If a $75 increase has even a 30% chance of pushing a good tenant out, the expected cost of that risk often exceeds the upside.

The defensible number is the one that captures most of the market gap without crossing your tenant's "I'll just move" threshold. For a quality long-term tenant, that's usually below the absolute market max. For a unit that's badly under market with a tenant who'd struggle to find better, you can push closer.

Make it defensible — to your tenant and to yourself

The other half of the battle is communication. A renewal increase lands very differently when it arrives as a vague "rent is going up $100" text versus a clean letter that references local market conditions and gives the tenant proper notice. Tenants accept increases they understand. A professional, comp-backed renewal letter dramatically lowers the odds of a "we're moving out" reply.

Stop guessing — run the number in two minutes

This is exactly the problem we built the RentReady Lease Renewal Calculator to solve. You plug in your current rent, market rent, and turnover costs, and it gives you a recommended increase that balances upside against vacancy risk — plus a ready-to-send, professional renewal letter you can hand to your tenant. No spreadsheet, no guessing, no property manager fees.

If you've got a renewal coming up and you're staring at the lease wondering what number to write down, run it through the calculator here and get a number you can actually defend.

Bottom line

Raising rent at renewal isn't about being aggressive or generous — it's about not leaving money on the table while not triggering an expensive vacancy. Do the math on the increase versus the true cost of turnover, communicate it professionally, and you'll keep good tenants and grow your income at the same time.
