Across the small and mid-size Twin Cities buildings we work on, the gap between a well-run property and a neglected one is usually $40 to $120 per unit per month in NOI — and almost none of it comes from rent increases. It comes from vacancy days, emergency call-outs at premium rates, and exterior systems that were allowed to fail on their own schedule instead of yours.
Where cash flow actually leaks
| Leak | Typical annual cost (50 units) | Fix |
|---|---|---|
| Slow turns (14 days vs. 7) | $18,000–$35,000 in lost rent | Pre-scheduled turn crew, materials staged |
| Emergency water calls | $8,000–$25,000 | Same-day mitigation vendor on file, shutoff mapping |
| Deferred roof/gutter work | $10,000+ in interior damage | Annual exterior inspection |
| Tree failures on parking/roofs | $5,000–$40,000 per event | Hazard pruning on a 3-year cycle |
| Repeat trip charges | $3,000–$9,000 | One vendor covering multiple trades |
1. Cut vacancy days, not rent
Every vacant day on a $1,400 unit costs about $46. Shaving a 14-day turn to 7 days on 30 turns a year recovers roughly $19,000. The lever is scheduling, not labor: a turn that starts the morning after keys drop, with paint and flooring already spec'd for the building, finishes in half the time of one that starts with three bids.
Standardize finishes building-wide so nothing has to be matched or ordered. One paint color, one LVP SKU, one cabinet hardware line.
2. Stop buying emergencies at emergency prices
After-hours water and storm work is priced two to three times daytime rates when you are calling strangers at 11pm. Owners who name a vendor in advance pay a normal rate and get triage instructions on the first call — which is usually what limits the damage.
3. Spend on the envelope, save on the interior
Roofs, gutters, siding, grading, and trees are the four systems that generate interior damage in Minnesota. A $900 gutter and downspout correction stops a recurring basement seepage claim. A $2,400 hazard limb removal avoids the $22,000 roof-and-unit event.
4. Make capital projects pay their own way
Not all capex is equal. Work that reduces operating cost or insurance exposure — roof replacement, siding, drainage, tree removal near structures — pays back whether or not you push rent. Work that only supports rent (kitchen upgrades, amenity space) should be tested on a few units before rolling through the building.
5. Consolidate vendors
Every additional vendor is another trip charge, another COI to chase, another schedule to coordinate, and another handoff where something falls through. Buildings that use one licensed contractor across tree, roofing, siding, fencing, and interior turn work consistently report fewer repeat visits and faster closeouts.
What this looks like on a 50-unit building
- 30 turns a year, 7 days faster: +$19,000
- Two avoided water events: +$12,000
- Emergency work at daytime rates: +$6,000
- One avoided tree/roof event every three years: +$8,000/yr amortized
That is roughly $45,000 a year on a building that never raised rent a dollar.

Frequently asked questions
What is the fastest way to improve NOI on a small apartment building?
Shortening turn time. Every day a $1,400 unit sits empty costs about $46, so cutting a 14-day turn to 7 days across 30 turns recovers roughly $19,000 a year with no rent increase.
Is deferred exterior maintenance really that expensive?
In Minnesota, yes. Roof, gutter, grading, and tree issues are what generate interior water damage. A few hundred dollars of drainage correction routinely prevents five-figure interior repairs.
Do you work with property management companies?
Yes. We work with owners, on-site maintenance managers, and regional directors across the Twin Cities metro, and provide W-9 and certificate of insurance on request.
