It's the second week of November. If your tenant's lease ends in February, March or April, the renewal conversation is about to start, and the number you put in that offer is one of the biggest financial decisions you make on a single-family rental all year.
Owners tend to get this wrong in one of two directions. Some leave rent flat for years because they're afraid of a vacancy, and quietly fall behind the market. Others push to the full market number every time and pay for it in turnover. The right answer is arithmetic, not instinct, and the arithmetic is simple enough to do on a napkin.
What's happening right now
Rates are a big part of why renters stay put. Freddie Mac's weekly survey put the 30-year fixed mortgage at 7.18% on November 5, down for a third straight week but well above the 6.22% of a year ago. Meanwhile, the Twin Cities sales market is soft on volume and not on price. Minnesota REALTORS data for September, the latest released as of this writing, shows the Twin Cities metro median sale price at $395,000, up 1.3% from a year earlier, with pending sales down 11.7%, inventory up 11.2% and a median of 48 days on market.
Prices are not falling, so don't read this as a collapsing market. But a tenant weighing a purchase against a renewal is looking at a monthly payment that's substantially higher than it was last year. That tends to make renters a little stickier. It doesn't make them immune to a big increase, which is exactly why the math matters.
What a turnover actually costs
Turnover cost has three parts: rent you don't collect while the house is empty, the make-ready work between tenants, and the cost of finding the next one. Every house differs, so treat the following as an illustration, not a quote. Take a $2,300 a month single-family rental and assume:
- 35 days vacant, about $2,683 in lost rent
- $1,200 in make-ready (paint, carpet cleaning, minor repairs, deep clean)
- $1,150 for leasing, equal to half a month's rent, covering marketing, showings, and screening
That's roughly $5,033 every time the house turns. Your own number could be lower or well above this. If you have our Vacancy Calculator handy, run your own figures through it.
The break-even rule
Here's the part worth remembering. If you raise the rent by X and the tenant stays, you gain 12 months of X. If you raise it and the tenant leaves, you incur the turnover cost, but the next tenant presumably pays the higher rent as well. So the extra increase only costs you money if it causes a tenant who would otherwise have stayed to leave.
The break-even is: annual gain from the increase ÷ turnover cost = the extra chance of losing the tenant you can afford to take on.
At $2,300 a month and a $5,033 turnover:
| Increase | Monthly | Annual gain | Break-even extra move-out risk |
|---|---|---|---|
| 3% | $69 | $828 | 16.5% |
| 5% | $115 | $1,380 | 27.4% |
| 8% | $184 | $2,208 | 43.9% |
Read the 5% row this way: a $115 increase pays off unless it raises the odds this tenant leaves by more than about 27 percentage points. For a tenant who pays on time and takes care of the house, a $115 bump is unlikely to pose much additional risk. For the 8% row, the increase pays off unless it makes the tenant more than about 44 percentage points more likely to leave. That's a much bigger bet than it sounds, and it's the one most owners implicitly make when they push for the full market number.
How the vacancy length changes everything
The assumption of vacancy moves the answer more than anything else. At the same rent:
| Vacancy | Turnover cost | 3% break-even | 5% break-even | 8% break-even |
|---|---|---|---|---|
| 21 days | $3,960 | 20.9% | 34.8% | 55.8% |
| 35 days | $5,033 | 16.5% | 27.4% | 43.9% |
| 60 days | $6,950 | 11.9% | 19.9% | 31.8% |
A house that rents in three weeks tolerates a much more aggressive renewal than one that sits two months. Winter lengthens vacancies for most Twin Cities houses, so a February or March move-out costs more than the same move-out in June. We worked through what winter vacancy does to the rent-cut decision in our October post on empty rentals; the same logic runs in reverse here. A renewal in the cold months is worth protecting.
The Minnesota rules that apply to the renewal itself
Automatic renewal clauses need a reminder. If your lease renews automatically, Minn. Stat. § 504B.145 requires the landlord to give the tenant written notice identifying the renewal provision. It has to be served personally or mailed by certified mail at least 15 days, but not more than 30 days, before the date the tenant must give notice that they're leaving. The statute doesn't spell out a penalty for skipping the notice, so a court could well refuse to enforce the automatic renewal against the tenant. Ask your attorney, and put the dates on a calendar.
Month-to-month tenants get notice equal to the rent period. Under § 504B.135, a tenancy at will is terminated by written notice for at least the rent interval, capped at three months. For a monthly tenant, that means a full month. Read your lease for any longer notice you've promised, and don't count on a verbal heads-up.
St. Paul has a cap. If the house is in St. Paul, rent increases are limited to 3% in a 12-month period unless you qualify for an exception. The city lists self-certification for increases between 3% and 8%, a partial vacancy decontrol of CPI plus 8% after a just-cause vacancy, and an exemption for newer construction (the city ties it to when the property first received a certificate of occupancy, and you have to ask the city to confirm it). Exceptions above those tiers need city review and approval. Check the city's current rules before you write the offer. In St. Paul, the break-even question changes: if you can only charge 3%, the table above says almost any increase is worth taking because the additional turnover risk is small.
Minneapolis has no residential rent cap in effect as far as the city's own housing-policy page shows, and any cap would need voter approval. Other metro cities set their own rules, and ordinances change. Verify with your city before you send anything.
Honest caveats
The model above is a simplification. It assumes the next tenant pays the higher rent, and that's only true if the market supports it. If you're already at or above market, a new tenant won't pay more, and the increase gain from turnover disappears. It also ignores the harder-to-count costs of turnover: a new tenant is a new risk of late pay, damage, or an eviction, which is why a proven tenant is worth more than the spreadsheet says. And the move-out probabilities are judgment calls, not data. Nobody can tell you precisely how a given tenant will react.
The other limit is that rent for single-family homes varies by locality. A three-bedroom in Lakeville isn't a three-bedroom in Frogtown. Before you pick a number, look at what comparable houses are really renting for, not what they're listed at.
What we'd tell you if you called
Go in with a number and a reason. For a good tenant, we'd usually point you toward a moderate increase that closes part of the gap to market rather than all of it, and we'd send the offer early enough that the tenant has time to decide without feeling cornered. We'd also tell you to look at the house before you renew: if the furnace is old or the carpet is shot, renewal is the cheapest moment to fix it.
If you're asking whether to push to the full market number, run the break-even for your own house with your own vacancy estimate. If the break-even is 40%+ and the tenant is solid, take the increase. If it's under 15% and the tenant is excellent, think hard before you squeeze.
