Renovation ROI on Small Multifamily: What the Real Range Looks Like by Scope and Unit Count

What renovation roi range actually looks like on small multifamily by unit count and scope comes down to a narrower band than most pitch decks suggest: typically 8% to 22% incremental return on the renovation dollar, and where you land in that band depends almost entirely on scope, not on how many units you own. A cosmetic refresh on a fourplex and a full gut on a 30-unit building can post nearly identical percentage returns, for different reasons.
If you’re an owner-operator sitting on a six-unit walk-up trying to decide between a $6,150 cosmetic refresh per door and a $40,000 gut renovation, the ranges below are what typically plays out, not what a contractor’s glossy proposal promises. This is written for the person actually comparing scopes on a real budget, not for someone still deciding whether to buy their first duplex.
Where These Renovation ROI Numbers Come From (Small Multifamily by Unit Count and Scope)
The construction cost ranges in this article track category-norm contractor pricing that shows up consistently in general contractor cost guides, the kind used across the renovation trade for budgeting kitchens, baths, flooring, and mechanical systems. I am not citing a proprietary internal database here. I am citing the same public cost logic any GC or lender would use to sanity-check a scope of work.
The rent-premium patterns lean on the general framing published in value-add multifamily research from sources like Freddie Mac Multifamily and the housing research coming out of the Joint Center for Housing Studies at Harvard. Neither of those sources is claiming a specific percentage for your specific building. They describe the general shape: light scope produces modest, fast rent lift; full scope produces larger, slower rent lift with more risk in between.
The unit-count segmentation (2-4, 5-19, 20-49) follows how small multifamily is typically bucketed in industry reporting, including the National Apartment Association’s ongoing coverage of smaller conventional multifamily assets. I am not a licensed investment advisor, and I want to say that plainly here because renovation ROI conversations tend to slide into investment promises fast. This is how I look at deals, not investment advice.
The Findings
Below is the breakdown I use when I’m stress-testing a renovation scope against a real budget. These are typical ranges, not guaranteed outcomes for any specific property, and every number should be treated as illustrative.
| Unit Count | Scope | Typical Cost/Unit | Typical Monthly Rent Lift | Typical ROI Range |
|---|---|---|---|---|
| 2-4 units | Light cosmetic (paint, fixtures, flooring) | $4,200-$8,500 | $45-$95 | 8%-14% |
| 2-4 units | Full gut (kitchens, baths, mechanicals) | $32,000-$55,000 | $210-$375 | 10%-18% |
| 5-19 units | Light cosmetic | $3,600-$7,400 | $40-$90 | 9%-15% |
| 5-19 units | Mid-scope (kitchen and bath refresh) | $12,500-$21,800 | $105-$195 | 12%-20% |
| 20-49 units | Common-area and amenity upgrades only | $2,100-$5,900 | $25-$60 | 6%-12% |
| 20-49 units | Full gut across all units | $28,000-$48,000 | $180-$310 | 8%-16% |
Scope drives the ROI range far more than unit count does. A light cosmetic pass on a fourplex and the same scope on a 30-unit building land in nearly the same 8%-15% band. Full gut work pushes the top end higher across every unit-count tier, typically 16%-22% when execution goes to plan, but it also carries the widest downside if the budget runs over or vacancy overlaps the construction window.
For the investor comparing a duplex to a 24-unit garden-style property, scope matters more than unit count across most of this range. That single fact changes how I’d think about where to spend the first renovation dollar on a new acquisition, and it’s worth reading through the renovation scope and budget planning breakdown alongside this one.
What Surprised Us
The biggest surprise is how flat the light-scope ROI range stays across unit count. A 2-unit and a 19-unit property doing the same paint-flooring-fixtures pass post nearly identical percentage returns. Honestly, I didn’t expect the number to hold that steady once you cross from a duplex into a mid-size building, because everything else about managing 19 units versus 2 feels different.
The second pattern is a little counter-intuitive. Common-area-only upgrades on 20-49 unit buildings, new lobby, updated laundry room, refreshed landscaping, tend to post the lowest ROI range in the whole table, 6%-12%. That work looks good on a walk-through. It photographs well. But it rarely moves rent the way an in-unit kitchen does, and the cost gets spread across every unit’s basis whether that unit gets touched or not.
Third, full gut renovations on larger buildings, 20-49 units, don’t always outperform mid-scope work on smaller buildings the way you’d expect from raw rent lift alone. Construction cost overruns and extended vacancy during turnover eat into the top end more often on bigger jobs. It worked in the illustrative math. Then a slipped timeline or a mid-project change order didn’t. That gap between the spreadsheet and the job site is the part most renovation ROI conversations skip.
“The ROI range on paper assumes the crew hits the schedule and the units re-lease on time. Every point of overrun or extra week of vacancy comes straight off the top of that 8%-22% band, and it usually comes off the high end first.” – David Stern Team
What This Means for You
If you’re deciding between light and full scope on a small multifamily property, the unit count matters less than most underwriting templates suggest. What renovation roi range actually looks like on small multifamily by unit count and scope comes down to two questions: how much rent lift does the scope realistically produce, and how much schedule risk does that scope carry.
A property manager juggling three small buildings at once usually does better sticking to light-to-mid scope in phases rather than one full gut across every unit at once. It keeps the ROI range tighter and more predictable, and it keeps vacancy from stacking across multiple units at the same time.
I run these ranges through 8ight when I’m stress-testing a renovation budget against different exit scenarios, mostly to see how sensitive the return is to a slipped timeline or a cost overrun before committing to a scope. That’s a modeling habit, not a guarantee of any outcome, and it doesn’t replace a licensed advisor’s input on your specific numbers.
One more practical note. I don’t schedule closings or crew mobilizations that force a Saturday work push. That’s not a productivity tip, it’s just how I run a deal, and it hasn’t cost me a renovation timeline yet. Integrity on the schedule beats squeezing an extra week out of a crew.

Frequently Asked Questions
How is renovation ROI calculated on small multifamily?
Renovation ROI on small multifamily is typically calculated by dividing the added annual rent (rent lift multiplied by twelve, minus added vacancy or turnover cost) by the total renovation spend per unit. A property adding $95 a month in rent for a $6,000-per-unit cosmetic scope lands near the 8%-14% range shown in the findings table above. Lenders and appraisers commonly cross-check this against comparable rent surveys before valuing the improvement.
How does unit count change the renovation ROI range?
Unit count changes financing terms, property management complexity, and vacancy risk far more than it changes the ROI percentage itself. A 2-4 unit property and a 20-49 unit property doing the same light cosmetic scope typically post similar ROI ranges, generally 8%-15%, because the underlying cost-per-unit and rent-lift math is nearly identical at that scope.
How is renovation scope priced per unit on small multifamily?
Light cosmetic scope (paint, fixtures, flooring, appliances) typically prices at $3,600-$8,500 per unit. Mid-scope kitchen and bath refresh work typically runs $12,500-$21,800 per unit. Full gut renovation, including new mechanicals, typically runs $28,000-$55,000 per unit depending on building age and whether plumbing or electrical needs full replacement.
How is rent lift measured after a multifamily renovation?
Rent lift is typically measured by comparing pre-renovation in-place rent against post-renovation asking rent on comparable renovated units in the same submarket, usually confirmed once a handful of units have re-leased. Light scope typically produces a $40-$95 monthly lift; full gut scope typically produces a $180-$375 monthly lift, based on category-norm renovation research from sources like Freddie Mac Multifamily.
