Everyone talks about "value-add" multifamily. Buy a tired building. Renovate the units. Raise the rents. Force appreciation. It sounds clean on a podcast. It looks great in a pitch deck.

But nobody shows you the spreadsheet from the middle of the project, when you're $4,000 over budget on unit 3, your flooring guy ghosted you, and the rent increase you underwrote isn't hitting because you overestimated market demand by $75/month.

We've renovated units across our portfolio. Some went exactly as planned. Some taught us expensive lessons. Here are the real numbers, real timelines, and real outcomes from a B-class unit renovation in Omaha that we completed last year. Not the highlight reel. The whole story.

The Starting Point

The unit was a two-bedroom, one-bathroom in a 1970s-built brick building in the Benson submarket. Approximately 850 square feet. The tenant had lived there for six years and moved out voluntarily at the end of their lease.

Pre-renovation condition:

Original laminate countertops, chipped and stained

Carpet throughout (original from the last renovation, roughly 8 years old, heavily worn)

Dated light fixtures, some with pull chains

Bathroom had a fiberglass tub surround that was yellowing

Appliances were functional but mismatched (white stove, black fridge, no dishwasher)

Paint was a dark beige that made every room feel smaller

Hollow-core interior doors, some with damage

Pre-renovation rent: $795/month. The tenant had received one $25 increase in six years. Market rent for comparable unrenovated units in the area was $825-$850. Market rent for renovated units was $1,025-$1,100.

The rent gap was the opportunity. If we could bring the unit to renovated-comp quality for the right price, the return on investment would justify the spend.

The Budget: What We Planned

Before we started demo, we built a line-item budget based on contractor quotes and material pricing. Here's what we planned:

| Item | Budgeted Cost | |------|--------------| | LVP flooring (850 SF installed) | $3,400 | | Kitchen countertops (laminate, new) | $1,200 | | Appliance package (stove, fridge, dishwasher) | $1,800 | | Bathroom tub surround | $950 | | New vanity and mirror | $450 | | Light fixtures (7 total) | $350 | | Interior doors (5) | $625 | | Paint (full unit, 2 coats) | $850 | | Electrical (add dishwasher circuit, update outlets) | $600 | | Hardware (cabinet pulls, door handles, towel bars) | $275 | | Contingency (10%) | $1,050 | | Total Budget | $11,550 |

Timeline estimate: 18 calendar days from start to listing-ready.

What Actually Happened

The renovation took 24 calendar days and cost $13,175. Here's where the budget went sideways.

Flooring: $3,400 budgeted, $3,850 actual

When we pulled the carpet, we found water damage around the bathroom doorway that had been hidden. The subfloor needed repair before LVP could go down. That was an extra $450 we didn't anticipate. Not a surprise if you've done enough of these; hidden damage under carpet is practically a guarantee in 1970s buildings.

Electrical: $600 budgeted, $1,100 actual

The dishwasher circuit was straightforward. But when the electrician opened up the panel, he found two circuits on a double-tap that weren't to code. We could have ignored it. We didn't. Bringing those up to code was another $500, but it was the right call. We don't cut corners on electrical.

Bathroom: $1,400 budgeted (surround + vanity), $1,825 actual

The tub surround removal revealed mold behind the old surround. We had to remediate before installing the new surround. Mold remediation on a small area like this isn't a five-figure disaster, but it added $425 in treatment, drying time, and re-inspection.

Timeline: 18 days planned, 24 days actual

The subfloor repair and mold remediation added 4 days. A scheduling conflict with our countertop installer added another 2 days. Six days over schedule.

Total overrun: $1,625 over budget (14% over). Not catastrophic. But that contingency we built in? Gone on the first surprise, with more surprises behind it.

The Rent Outcome

We listed the renovated unit at $1,075/month. Here's the market context:

Unrenovated comps in the area: $825-$850

Renovated comps: $1,025-$1,100

Our target: mid-range of renovated comps

The unit leased in 11 days. The tenant who signed was a young professional relocating for work; exactly the demographic that pays a premium for move-in ready units with updated finishes.

Monthly rent increase: $280/month ($795 to $1,075).

The ROI Math

This is where the spreadsheet gets interesting.

Total renovation cost: $13,175

Annual rent increase: $3,360 ($280 x 12)

Simple cash-on-cash return on renovation spend: 25.5%

That's strong. But let's look at the full picture, including the costs that most "value-add" analyses conveniently omit.

Vacancy during renovation: 24 days. At the old rent of $795/month, that's roughly $636 in lost rent during the renovation period.

Vacancy during leasing: 11 days. At the new rent of $1,075/month, that's roughly $394 in lost rent during the leasing period.

Total vacancy cost: $1,030

Total all-in cost: $14,205 (renovation + vacancy loss)

Adjusted cash-on-cash return: 23.7%

Still strong. But $14,205 is a different number than $11,550. That 22% gap between original budget and actual all-in cost is the gap between the pitch deck and reality.

The Forced Appreciation Effect

Here's where the investment thesis gets more compelling. In commercial multifamily (5+ units), property value is driven by NOI. If this renovation is part of a larger building renovation, the rent increases across multiple units stack up in the valuation.

Suppose we renovate 8 units in a 12-unit building, each achieving a $250/month average rent increase.

Additional annual NOI: $24,000 ($250 x 8 x 12)

At a 7% cap rate (reasonable for B-class Omaha multifamily), that additional NOI translates to roughly $342,857 in added property value.

If the total renovation cost across 8 units was $105,000, the forced appreciation multiple is approximately 3.3x. For every dollar spent on renovation, $3.30 was created in property value.

That's the real value-add story. Not any one unit, but the portfolio-level impact of systematically upgrading and re-pricing.

Lessons From the Renovation

Lesson 1: Your contingency should be 15-20%, not 10%

On a 1970s building, 10% contingency is optimistic. We've adjusted our standard to 15% for buildings built before 1985 and 20% for anything before 1970. Hidden conditions are the rule, not the exception.

Lesson 2: Scope creep is your biggest budget risk

Every renovation has a moment where you're standing in the unit thinking "while we're in here, we should probably also replace the..." Stop. If it wasn't in the original scope and it isn't a safety issue, it goes on the list for the next turn. Scope creep killed more renovation budgets than material cost increases.

Lesson 3: Schedule your contractors before you start demo

We had our countertop installer's schedule locked in before demo day. But a job ahead of us ran over, pushing our install back 2 days. Now we've started scheduling backup windows with secondary vendors for any trade that's on the critical path.

Lesson 4: Don't over-renovate for the market

We considered quartz countertops instead of laminate. The cost difference was about $1,800. Would quartz have commanded an additional $25/month in rent? Maybe. That's a 6-year payback on the upgrade. Laminate that looks like quartz costs half as much and achieves 90% of the rent premium. Know where the diminishing returns start.

Lesson 5: Document everything

Before photos. During photos. After photos. Every receipt. Every change order. Every conversation with a contractor about scope changes. This documentation supports your insurance claims, your tax depreciation-actually-works) schedules, your refinance appraisals, and your investor reporting.

The Bottom Line

Unit renovations work when the math works. And the math only works when you're honest about the real costs, not the best-case scenario costs.

Budget conservatively. Plan for surprises. Track every dollar. And before you start, know exactly what rent the market will support for a renovated unit in your specific submarket, because that number is the ceiling on your entire investment thesis.

The gap between a good renovation and a bad one isn't the quality of the finishes. It's the quality of the planning.
