Property Management Cost & Reserve Toolkit
Four connected worksheets: management cost, tenant turnover, maintenance and capital reserves, and the market rent gap. Every section updates as you type and feeds the combined monthly summary at the bottom.
Section 1
Self-manage vs. hire a property manager
Compare the manager's monthly fee against the value of your own time.
Typical range 8–10%.
Typical range 50–100%, spread over 12 months.

Self-managing costs about $55 less per month, as long as you actually have those hours free.

50% means one turnover every two years.

Annual reserve
$3,200
Share of monthly rent
13.33%

- $267
- Sq ft rule monthly
- $320
- Method in use
- 1% rule
This reserve should sit in a separate account, untouched, for roof/HVAC/major systems replacement.
Section 4
Rent increase / market rent gap
See how far below market the unit sits and what a fair renewal increase looks like.
Leave blank if no cap applies.
Results
Rent gap
$250
Below market
Gap as % of current rent
12.50%
Recommended increase this renewal
$250
- New rent after increase
- $2,250
- Max allowable rent with cap
- No cap entered
- Added annual income
- $3,000
- Tenant tenure
- 3 years
A long-tenured tenant is worth weighing against a full jump to market — turnover cost in Section 2 is the trade-off.

About this calculator
This toolkit combines four linked worksheets for rental property owners: whether to self-manage or hire a property manager, what a single tenant turnover really costs, how much to reserve monthly for maintenance and capital repairs, and how a current rent compares to market rent. Together they build toward one combined estimate of true monthly cost of ownership.
How it works in plain English
The first section compares the cost of hiring a property manager, a management fee percentage of rent plus a leasing fee spread over twelve months, against the value of your own time spent self-managing, calculated as hours spent per month times your hourly value. The second section estimates the cost of one tenant turnover by adding lost rent during the vacancy period, cleaning and repair costs, and marketing costs, then spreads that cost across a year using a historical turnover rate to get an annualized figure.
The third section sets a maintenance and capital reserve using one of two standard methods: the 1% rule, which sets aside 1% of property value per year, or a square-footage rule that applies a per-square-foot monthly rate, generally higher for older properties. The fourth section compares current rent to market rent to find the rent gap, then applies an optional cap on how much a lease can be raised at renewal to produce a recommended increase.
A combined summary at the bottom adds the management cost, the annualized turnover cost spread monthly, and the maintenance reserve into one estimate of total monthly cost of ownership beyond the mortgage itself, useful for budgeting or comparing properties.
The formula
- Cost to hire = rent x PM fee% + (rent x leasing fee% / 12)
- Cost to self-manage = hours per month x hourly value
- Turnover cost = (vacancy days / 30 x rent) + cleaning costs + marketing costs
- Annualized turnover cost = turnover cost x historical turnover rate
- 1% rule reserve (monthly) = property value x 1% / 12
- Sq ft rule reserve (monthly) = square footage x rate per sq ft
- Recommended rent = lesser of market rent or current rent x (1 + cap%), but never below current rent
Worked example
A landlord with a $2,000/month rental compares a property manager charging 9% of rent plus a 75% leasing fee spread over the year (about $305/month) against spending 5 hours a month self-managing at $50/hour ($250/month); self-managing wins by about $55/month here. For turnover, 21 vacancy days, $1,200 in cleaning, and $400 in marketing add up to $2,940 per turnover, or about $1,470/year and $123/month at a 50% annual turnover rate.
For reserves, a 25-year-old, 1,600 sq ft home valued at $320,000 using the 1% rule sets aside about $267/month. If market rent is $2,250 against a current rent of $2,000, that's a $250 rent gap (12.5%), which a 5% renewal cap would trim down to a $100 recommended increase.
Typical property management fee ranges
| Fee type | Typical range |
|---|---|
| Monthly management fee | 8% - 10% of collected rent |
| Leasing / placement fee | 50% - 100% of one month's rent |
| Maintenance reserve (1% rule) | 1% of property value per year |
| Maintenance reserve (sq ft rule) | $0.10 - $0.30 per sq ft per month |
Ranges reflect commonly cited industry rules of thumb and vary by market and service level.
Frequently asked questions
Should I always hire a property manager if it's cheaper than my time?
Not necessarily. The comparison only measures dollar cost against the value you assign to your own hours; it doesn't capture your comfort with tenant issues, distance from the property, or whether you actually have flexible time. Use the numbers as one input, not the only factor.
Why does the turnover cost use a percentage rate instead of a fixed schedule?
Turnover rates vary widely by tenant type, lease length, and local market conditions, so a percentage lets you plug in your own property's history rather than assume a fixed cycle. A 50% rate means, on average, one turnover every two years; a 100% rate means turnover every year.
Which maintenance reserve method should I use?
The 1% rule is a simple starting point tied to property value, while the square-footage method more directly reflects physical size and age, since older or larger properties generally need higher per-square-foot reserves. Many owners compare both and lean toward whichever produces the more conservative (higher) number.
Why would I cap my own rent increase below market rent?
Some leases, local ordinances, or landlord preferences limit how much rent can rise at one renewal, even if market rent has moved further. Capping the increase can also help retain a reliable tenant, since large sudden jumps often trigger turnover, which the toolkit's own turnover section shows can be costly.
Does the combined monthly cost include the mortgage payment?
No. The combined total in this toolkit adds management cost, annualized turnover cost, and the maintenance reserve, but leaves out the mortgage payment, since that depends on financing chosen separately for the property, not on operating the rental itself.
