Hiring a Property Manager in St. Louis: What to Ask Before You Sign

Revised August 16, 2026

Imagine it’s a Tuesday in February, 10:40 at night, and your phone lights up. It’s the tenant in the little brick two-bedroom you own in Affton. No heat. You have a meeting at eight, no furnace guy, and you’re about to learn what every landlord learns eventually — the hard part of owning a rental is never the rent.

Maybe your version is the duplex in Florissant you inherited. Maybe it’s the ranch in St. Charles you couldn’t sell, so you rented it. Maybe it’s a condo in Belleville, where the landlord rules you learned on the Missouri side don’t all apply.

One rental is a hobby. Two is a second job. Somewhere in there most owners price out a property manager, and the pricing is where it gets murky.

Should you hire a property manager for your St. Louis rental?

Hire one when the distance, the door count or the day job stops working. The practical test: if you own more than a unit or two, live more than half an hour away, or can’t leave work to meet a furnace tech, a manager usually costs less than the vacancy and the bad tenant placement you’ll absorb without one.

A manager does four jobs — price and market the unit, screen and place the tenant, collect rent and account for it, coordinate repairs and legal notices. Only the third automates easily, and it’s the one owners think they’re paying for. One house twenty minutes away with a plumber you trust is a real argument for self-managing. Three across Florissant, Affton and Belleville while working full time is not.

What percentage do most property management companies charge?

Expect a stack, not a single number. St. Louis firms commonly advertise 8% to 12% of monthly rent, and several publish flat alternatives in the $100 to $180 range with a minimum near $100 a month. Treat that headline carefully: no public survey backs it — it’s the range operators post, not a measured average.

The leasing fee moves your return more than the percentage does, and it’s the most consistent figure in the trade — 50% to 100% of one month’s rent to place a tenant. On a house renting at $1,600, that’s $800 to $1,600, charged again every time a tenant leaves. Zillow reported on May 28, 2025 that listing views, applications and renter outreach to property managers all peak in the first week of June.

Renewal fees are where the metro splits. Some St. Louis companies charge a flat $100 to $300 when a tenant re-signs; others charge 25% to 50% of one month’s rent — $250 against $800 for one signature. For scale, the average apartment rent in St. Louis was $1,443 as of August 1, 2026, with three-bedrooms at $1,786, per RentCafe’s Yardi Matrix data.

Which property management fees actually surprise landlords?

How much is a reasonable management fee? Not a question the headline number answers. The management percentage is rarely where contracts diverge. Start with the two-word difference that changes the whole deal: whether the fee is charged on rent collected or on rent due. On rent due, you keep paying while a tenant is delinquent or the unit sits empty.

Then price the rest. A one-time setup charge, around $300 here. A minimum monthly fee, often about $100, which quietly turns a percentage deal into a flat one on a cheap unit. A vacancy fee, billed flat or as a share of expected rent. Inspections, roughly $75 to $150 a visit, or about $149 for an annual condition report. Eviction handling, often an annual add-on near $200, or roughly $500 a case plus legal costs.

Two more need a direct question. Maintenance markup is a percentage added on top of the vendor’s invoice, and there’s no industry rate for it — some St. Louis firms advertise none at all, while elsewhere a project-management charge near 10% of project value shows up. And ask who keeps the late fee; some agreements let the manager keep a quarter to half of it.

Does a property manager in Missouri need a real estate license?

Yes, in almost every third-party arrangement. RSMo 339.010 defines a real estate broker as anyone who, for another and for compensation, rents or leases real estate, offers to rent or lease it, or negotiates the rental or leasing of it. Managing someone else’s rental for a fee sits inside that definition.

The exemptions are narrower than owners assume. RSMo 339.010 exempts owners and lessors acting on their own property and their regular employees, licensed attorneys, and people acting as a receiver, trustee in bankruptcy, administrator, executor or guardian. It also exempts on-site personnel limited to enumerated clerical duties — showing units, delivering leases, receiving applications, deposits and rent for delivery to a broker or owner. That covers a leasing assistant, not a company running your house from across town.

The follow-on rule protects your money: under RSMo 339.105, a Missouri broker holding funds belonging to another must keep them in a separate bank account designated an escrow or trust account, with records available for Missouri Real Estate Commission inspection. Illinois runs a parallel system — under the Real Estate License Act of 2000, 225 ILCS 454, leasing residential property for someone else takes a residential leasing agent license, sponsored and employed by a sponsoring broker. Ask for the license number and look it up.

Nothing to do with leases — every building eventually needs an electrician.

How do Missouri and Illinois security deposit rules differ?

They differ on the cap and on the clock, and the Illinois half changed recently. Missouri caps the amount: RSMo 535.300 says a landlord may not demand or receive a security deposit in excess of two months’ rent. Illinois sets no statewide dollar cap at all.

Missouri then gives you thirty days. Within thirty days after the tenancy terminates, the landlord must return the deposit or deliver an itemized list of damages, and the tenant has the right to be present at the inspection. Get it wrong and the tenant recovers twice the amount wrongfully withheld.

Illinois used to let small landlords ignore its statute. Not anymore. The Security Deposit Return Act, 765 ILCS 710, was amended by Public Act 103-224 effective January 1, 2024, and the old five-or-more-units threshold is gone — it now reaches a lessor of residential real property generally. The landlord has thirty days from the date the tenant vacated to furnish an itemized statement of damage with paid receipts, and with no statement the full deposit goes back within forty-five days. The penalty is twice the deposit plus court costs and reasonable attorney’s fees.

Interest is where the old size test survived: 765 ILCS 715 still applies only to property with twenty-five or more units in one building or contiguous complex, on deposits held more than six months. Missouri requires no interest at all.

How much notice do you owe a tenant, and how fast is an eviction?

Missouri moves faster on unpaid rent than owners expect. Ending a month-to-month tenancy takes one month’s written notice under RSMo 441.060, terminating on a rent-paying date not less than a month after the notice is received. But for nonpayment, RSMo 535.020 says outright that the 441.060 notice is not required before filing — the landlord demands the rent and files if it isn’t paid. No statutory cure window sits at the front of it.

Illinois builds the cure window in. Nonpayment requires written notice giving the tenant not less than five days after service to pay, under 735 ILCS 5/9-209. Another lease breach takes ten days’ notice to quit under 9-210. Month-to-month takes thirty days, week-to-week seven, under 9-207. And under 735 ILCS 5/9-117, an eviction order can’t be enforced more than 120 days after entry unless the court grants an extension.

After judgment in Missouri, RSMo 535.110 controls: no trial de novo or appeal stays execution unless the tenant posts bond within ten days. Then there’s the courthouse. St. Louis City files in the 22nd Judicial Circuit and St. Louis County in the 21st — separate courts, separate sheriffs, separate dockets. Cross the river and you’re in the 20th for St. Clair County or the 3rd for Madison County. One metro, four systems.

What does St. Louis City require before a tenant moves in?

An inspection and a certificate, before anybody gets keys. City Ordinance No. 71835 requires a Housing Conservation District inspection, and a Certificate of Inspection must be obtained before a vacant residential unit is occupied. The application fee is $120, or $200 if a resident is found occupying a dwelling with no current certificate, plus $65 for each additional unit at one address. The certificate is good for twelve months. Outside the city line it fragments — unincorporated St. Louis County runs its own occupancy permit program with an inspection at change of occupant, and municipalities inside the county set their own rules.

What the job looks like from the management company’s side

The percentage model breaks first. Ten percent of an $800 unit is $80 a month, and one after-hours call plus a vendor dispatch spends that before the tenth — which is why minimum fees exist and cheap doors get quietly declined. Maintenance is the actual product: in Buildium’s 2026 industry report, 56% of owners named maintenance support as their main reason for hiring a manager, and it was also their top source of stress. Rent collection automated years ago; work orders didn’t, and AppFolio’s 3Q2025 update put the U.S. average near 54 rental units per employee. Turnover is the bill nobody wants: the National Apartment Association’s 2024 Income/Expense IQ data, published December 2025, shows turnover costs up 17.5% in a year and vacancy and rent loss at $1,323 per unit. Deferred maintenance and an owner who won’t approve a repair produce that bill on repeat, which is why good firms screen owners as carefully as tenants — and why one with room for another door wants a complete listing where owners already search.

What should you ask before signing a management agreement?

Seven questions, one phone call. Ask for the license number and look it up yourself. Ask whether the monthly fee is charged on rent collected or rent due. Ask for the entire fee schedule in writing, including the leasing fee, the renewal fee and any markup added to vendor invoices.

Then the operational four. What can they spend on a repair without calling you? Who keeps late fees and pet fees? How do you end the agreement, and is there a termination fee? And how many doors does each staff member carry — that predicts how fast a work order gets answered better than anything on a website. Get the answers into the agreement, not the email thread.

Frequently asked questions

How much do property managers charge in Missouri?

There is no set rate and no public survey of Missouri fees. St. Louis companies commonly advertise 8% to 12% of monthly rent, with flat alternatives around $100 to $180 a month and minimums near $100. Budget separately for the leasing fee, 50% to 100% of one month’s rent each time a tenant is placed, plus a renewal fee that is either a flat $100 to $300 or 25% to 50% of a month’s rent.

What percentage do most property management companies charge?

Eight to twelve percent of monthly rent is the range St. Louis firms advertise, alongside flat plans near $100 to $180 and minimums around $100 a month, which quietly turn a percentage deal into a flat one on a cheap unit. Ask whether that percentage is charged on rent collected or on rent due.

How much is a reasonable management fee?

Judge the stack, not the headline. The leasing fee moves your return more than the monthly rate does, at 50% to 100% of one month’s rent every placement, and renewals run either a flat $100 to $300 or 25% to 50% of a month. Then price setup near $300, inspections at $75 to $150, and any markup added to vendor invoices.

Do you need a real estate license to manage rental property in Missouri?

Generally yes. RSMo 339.010 defines a real estate broker to include anyone who, for another and for compensation, rents or leases real estate or negotiates a rental, so managing someone else’s property for a fee is licensed activity. Owners and their regular employees are exempt on their own property, as are attorneys and court-appointed receivers, trustees, executors and guardians.

How much can a landlord charge for a security deposit in Missouri?

No more than two months’ rent, under RSMo 535.300. The same section requires the deposit back, or an itemized list of damages, within thirty days of the tenancy ending, gives the tenant the right to be present at the inspection, and lets a tenant recover twice any amount wrongfully withheld.

How long does an Illinois landlord have to return a security deposit?

Thirty days to itemize, forty-five to refund. Under 765 ILCS 710 the landlord must furnish an itemized statement of damage with paid receipts within thirty days of the tenant vacating, and with no statement the full deposit is due within forty-five days. Public Act 103-224, effective January 1, 2024, removed the old five-unit threshold.

How much notice does a Missouri landlord have to give a tenant?

One month in writing to end a month-to-month tenancy, terminating on a rent-paying date at least a month after the notice is received, under RSMo 441.060. Unpaid rent works differently: RSMo 535.020 states the 441.060 notice is not required before filing a rent and possession statement.

Is a property manager worth it for one rental property?

Often not, if you live nearby and can take a repair call. At 8%, the monthly fee on a $1,600 house is about $128, but the leasing fee at placement runs $800 to $1,600, and one unit rarely bills enough to get prioritized. The case flips with distance or a second unit.

Can a property manager evict a tenant for you?

They handle the notice, the paperwork and the coordination, and many St. Louis firms price eviction coverage as an annual add-on near $200 or bill roughly $500 a case plus legal costs. A manager isn’t your lawyer, though, so ask specifically who appears in court.
