How Much Should You Raise the Rent?
The answer is rarely “to market immediately”, and it is never “nothing, ever”. The turnover math sets the ceiling.
8.4 years
How long a $50 rent increase takes to repay one turnover it triggered.
The arithmetic that governs it
Every renewal is the same trade: a certain gain against a probable cost. The gain is the increase, annualised. The cost is the chance you trigger a move, multiplied by what a move costs.
A $50 monthly increase on a $2,100 rental
- Annual gain
- $600
- Cost if it triggers a turnover
- $5,025
- Years to recover that turnover
- 8.4
- Break-even probability of triggering a move
- ≈ 12% per year of expected tenure
On a reliable tenant, small increases are close to a coin flip.
That figure comes straight from what a turnover actually costs, and it explains a pattern experienced landlords converge on: they raise rent on good tenants gently and reliably, and they save the real correction for the vacancy they were going to have anyway.
But never raising is worse
| Policy over 10 years | Rent in year 10 | What happens |
|---|---|---|
| No increases | $2,100 | Roughly 25% below market. The gap is now unbridgeable without a move. |
| 3% a year on renewal | $2,822 | Tracks the market. Each step is small enough to accept. |
| Nothing, then a correction at turnover | $2,822 eventually | You collect below-market rent for years, then take the turnover anyway. |
The third row is the trap, because it feels like the kind option. Holding rent flat for six years does not avoid the correction — it defers it, funds the tenant’s discount out of your return in the meantime, and then presents them with a 20% increase that is far more likely to trigger the move you were trying to prevent.
A below-market rent is also a valuation problem
A policy that works
| Situation | Reasonable move |
|---|---|
| Rent within 5% of market, good tenant | 2–3% at renewal. Small, predictable, expected. |
| Rent 5–10% below market, good tenant | 4–6% at renewal, with a plain explanation of why. Close the gap over two cycles rather than one. |
| Rent more than 15% below market | Do not attempt it on renewal. Plan the correction for the next turnover and budget the turnover. |
| Tenant is difficult or late-paying | Raise to market. The turnover risk is a feature here, not a cost. |
| Market is soft, comparable units sitting empty | Hold. A vacancy costs more than the increase is worth. |
| You have just improved the unit | Raise to what the improved unit is worth, and say what changed. |
How you deliver it changes the outcome
Before you send it
| Check | Why |
|---|---|
| Notice requirements | State and local law sets minimum notice — commonly 30 to 60 days, sometimes more for larger increases. Get this wrong and the increase is unenforceable. |
| Rent regulation | Caps exist in a growing number of jurisdictions, sometimes statewide, sometimes only for buildings above a certain age. Check before, not after. |
| Current market rent | Not your memory of it. Pull comps — see how to estimate rent. |
| Days on market for comparable units | If similar units are sitting empty at your target, the market has already answered. |
| The tenant's payment record | A tenant who has paid on time for three years is an asset. Price accordingly. |
The alternatives to a rent increase
If the goal is more NOI rather than more rent specifically, there are levers that carry no turnover risk at all: a property tax appeal, re-shopping insurance, recovering utilities, or adding a paid amenity such as storage or parking. Several of them are worth more than a $50 increase and none of them risk a $5,025 turnover — see nine ways to increase NOI.
Whatever you decide, run it through the calculator with the turnover cost attached, rather than treating the increase as pure gain. It is a different decision once both sides are on the page.
Frequently asked questions
How much should I raise rent each year?
Two to three percent a year on a good tenant whose rent is near market keeps you tracking the market with increases small enough to be accepted. Larger corrections are better timed to a turnover, when the cost of the move is already being incurred.
Is it worth raising rent if the tenant might leave?
Compare the annual gain to the cost of a turnover. On a $2,100 rental, a $50 increase produces $600 a year against a turnover costing roughly $5,025 — so it only pays if the chance of triggering a move is low. Larger increases change the arithmetic, and a difficult tenant changes it further.
How much notice do I need to give for a rent increase?
It depends on your state and city, and commonly runs from 30 to 60 days, with longer periods sometimes required for larger increases. Some jurisdictions also cap the increase itself. Check the local rule before sending anything, since an improperly noticed increase is generally unenforceable.
What if my rent is far below market?
Closing a gap of more than about 15% on a renewal usually triggers the move you were trying to avoid. The practical approach is to close it over two or three cycles, or to plan the full correction for the next turnover and budget for that turnover deliberately.
