How much should you raise rent at lease renewal?

Renewal pricing is a different problem than new-lease pricing. You are not just asking what the market will bear. You are weighing a rent increase against the real cost of losing a paying tenant.

Key takeaways

  • Turnover costs typically run 1-2 months of rent once vacancy, make-ready, marketing, and screening are added up, so a renewal increase that pushes a tenant out has to clear a high bar to be worth it.
  • The right increase depends on the gap between current rent and the HUD-anchored local market rent, not on a flat percentage applied to every unit.
  • National Apartment Association survey data puts per-unit turnover costs at roughly $1,000 to $5,000, with the largest single line item being lost rent during vacancy.
  • Renters move far more often than owners: Census Bureau data shows a 22.9% one-year renter mover rate versus 5.0% for owners, so retention math matters more for rental housing than it does for owner-occupied comparisons.
  • The RentalAnalytics lease renewal advisor automates this comparison: hold if you're at market, raise modestly if you're 5-12% under, reposition if you're more than 12% under.

Why is renewal pricing a different problem than new-lease pricing?

A vacant unit has no downside to pricing at full market rent. A renewal has a real cost on the other side of the decision: if the increase pushes the tenant out, you inherit vacancy days, make-ready work, marketing spend, and screening costs before a new lease starts. That is the retention-risk side of the ledger, and it is easy to ignore when you are only looking at the rent roll.

The tenant on a renewal is also a known quantity. You know their payment history and how they treat the unit. A new tenant is unknown until they move in. Pricing a renewal purely off "what a new listing would fetch" ignores the value of a proven tenant and the cost of finding out whether the next one is as good.

How much of a gap to market actually justifies an increase?

Start with a HUD-anchored estimate of current market rent for the unit, then measure the gap to what the tenant pays today. Three bands make the decision straightforward:

  1. Within 5% of market. Hold, or raise 2-3% to track inflation. The retention risk of a larger increase is not worth the small additional revenue.
  2. 5-12% under market. Raise 5-8%. This closes most of the gap without a jump large enough to be a common non-renewal trigger.
  3. More than 12% under market. A single increase big enough to close the gap raises turnover risk substantially. Plan a two-step increase across two renewal cycles, or accept that the unit may turn and get repriced to market at that point.

This is the same logic behind the RentalAnalytics lease renewal advisor, which compares the current rent to a HUD Fair Market Rent anchor for the ZIP code and outputs one of these three recommendations automatically.[1]

What does turnover actually cost?

More than most landlords budget for. A survey of property management firms compiled by the National Apartment Association found that per-unit turnover costs, covering lost rent during vacancy, cleaning, painting, marketing, and screening, typically fall between $1,000 and $5,000 depending on the scope of make-ready work.[2] The single largest line item in most breakdowns is lost rent during the vacancy period, not the physical make-ready work itself.

As a planning rule, budget 1 to 2 months of rent per turnover. On an $1,800-a-month unit, that is $1,800 to $3,600 in vacancy, make-ready, and leasing cost before the next tenant's first payment arrives. That number is the anchor for every renewal-increase decision that follows.

How do you run the actual math?

Compare the expected value of pushing the increase against the expected value of holding. A simplified version, using a $1,800 current rent and a turnover cost of 1.5 months of rent ($2,700):

IncreaseNew rentAnnual gain if tenant staysNet if tenant leaves instead
3%$1,854$648-$2,700 (turnover cost, no gain)
7%$1,926$1,512-$2,700
12%$2,016$2,592-$2,700

The larger the increase, the larger the annual gain if it sticks, but the loss if the tenant leaves is fixed at the turnover cost regardless of how big the increase was. A 12% increase only needs to succeed slightly more often than it fails to be worth it on expected value. A 3% increase is close to risk-free by comparison. The decision is not "should I raise rent," it is "does this specific increase clear its own breakeven odds of tenant retention."

How often do renters actually move, and does that change the math?

Yes. Renters move far more often than owners, which is exactly why retention economics matter more in rental housing than in most owner-occupied comparisons. Census Bureau data on geographic mobility shows a one-year mover rate of 22.9% for renters versus 5.0% for owners in the 2015-2016 period, a gap that has held since the Census first tracked tenure-based mobility in 1988.[3] A meaningful share of tenants leave for reasons that have nothing to do with rent, job changes, family moves, buying a home, so not every non-renewal is a pricing failure. But it also means the base rate of turnover is already nontrivial before you add a rent increase on top of it.

National rent growth context matters too. BLS CPI data for rent of primary residence showed the index at 446.945 in June 2026, up from 434.594 in June 2025, a year-over-year increase of roughly 2.8%.[4] That is a useful floor: a renewal increase below the CPI rent trend is not keeping pace with the broader market, even before accounting for a unit-specific gap to local market rent.

What about a tenant who is already above market?

It happens, usually after a market softens or the tenant signed during a peak. Do not cut rent at renewal just because the HUD anchor has drifted below current rent. Hold flat instead. A rent cut invites the tenant to expect further cuts and signals the market to a tenant who otherwise had no reason to shop around. If the gap is large, more than 10-15% above market, expect elevated non-renewal risk regardless of what you charge, and start planning for it rather than trying to price your way out of it.

Frequently asked questions

How much should I raise rent at lease renewal?

It depends on the gap between current rent and the HUD-anchored market rent for the unit. If current rent is already within 5% of market, hold or raise 2-3% for inflation. If it is 5-12% under market, raise 5-8%. If it is more than 12% under, a single jump risks turnover, so plan a two-step increase instead.

Is a 10% rent increase at lease renewal too much?

It depends on the starting gap to market. A 10% increase is reasonable if the unit is more than 10% under market. If the unit is already near market rent, a 10% jump has a meaningfully higher chance of triggering a move-out, and turnover typically costs 1-2 months of rent, which can erase the gain even if the increase sticks half the time.

What percentage under market rent justifies repositioning instead of a gradual increase?

More than 12% under the HUD-anchored market estimate. At that gap, a single modest increase will not close it and a large one raises turnover risk substantially. The better move is a planned two-step increase over consecutive renewals, or accepting turnover and repricing the unit to market once vacant.

How much does tenant turnover actually cost a landlord?

Industry surveys compiled by the National Apartment Association put per-unit turnover costs, covering vacancy, make-ready, marketing, and screening, at roughly $1,000 to $5,000 depending on scope of work. As a rule of thumb, budget 1 to 2 months of rent per turnover when deciding whether a renewal increase is worth the retention risk.

Should I ever hold rent flat at lease renewal?

Yes, when the unit is already at or near market rent and the tenant has a strong payment and care history. In that case the expected turnover cost outweighs the small gain from a 2-3% increase. Holding flat, or raising only enough to cover inflation, is often the higher-expected-value choice for an already-at-market unit with a good tenant.
