Planning a Rental Property Upgrade? Here’s How to Budget by Unit
Share this post
Introduction
If you’re a landlord or property investor, you already know this truth:
Every dollar you spend on a rental better bring something back.
Whether you’re upgrading a duplex, modernizing an aging fourplex, or renovating an entire 12-unit building, your biggest budgeting mistake is this:
Not planning costs per unit.
Budgeting by unit keeps your ROI sharp, your financing realistic, and your rent comps competitive. It also keeps your project organized—especially if you're dealing with staggered timelines, tenant occupancy, or phased improvements.
In this guide, we’ll walk through:
- Why per-unit budgeting is essential
- Typical per-unit renovation costs by project type
- Step-by-step planning using Estimero
- Smart upgrade strategies that pay off in rental markets
- Avoiding common budget traps in multi-unit remodels
💡 Why Budget by Unit?
Here’s what happens when you don’t:
- Overages multiply quickly (“It’s just $1,000 extra” x 10 = $10,000)
- Tenant timelines get messy
- Appraisals don’t reflect scope evenly
- You lose track of ROI by door
Budgeting per unit forces discipline—and reveals which upgrades make sense unit by unit, not just for the building overall.
💰 Common Rental Upgrade Costs (Per Unit in 2025)
| Upgrade Type | Budget (Basic) | Budget (Mid-Range) |
|---|---|---|
| Full paint & patch | $2,500 | $4,000 |
| Kitchen refresh | $5,000 | $8,500 |
| Bathroom refresh | $3,000 | $6,000 |
| Flooring (LVP install) | $3,000 | $5,500 |
| Fixtures (lighting, fans) | $1,000 | $2,000 |
| Appliances (basic set) | $2,500 | $4,000 |
| HVAC or mini-split | $4,500 | $8,000 |
| Total (avg/unit) | $21,500 | $38,000 |
📌 Multiply that by the number of units and you can see why per-door planning is critical.
🧠 Step-by-Step: Budgeting by Unit in Estimero
Step 1: Set Project Scope
Are you upgrading:
- All units at once?
- Only between tenant turnovers?
- Just kitchens and baths?
- Exterior shared areas too?
Step 2: Use the “Multi-Unit Renovation” Template
- Go to Estimero
- Select “Rental Property Upgrade – Multi-Unit”
- Input number of units (e.g., 4, 6, 12)
- Choose unit type: Studio / 1BR / 2BR+
- Pick material quality: Budget / Mid-Range / Premium
Estimero will auto-build a per-unit estimate structure you can edit line by line.
🔧 Step 3: Customize Each Unit Scope
Let’s say you have a 6-unit building and you’re doing:
- Kitchen + bath refresh
- Flooring
- Paint
- Appliances
Estimero Line Items (Per Unit):
- Kitchen cabinets (stock white shaker): $1,200
- Countertops (laminate): $800
- Faucet + sink: $300
- Bath vanity: $600
- Vinyl flooring (installed): $3,000
- Interior paint: $2,700
- Appliances: $2,800
- Labor (flat rate): $5,000
- Misc (permits, cleanup, trim): $1,200
- Contingency (10%): $1,360
- Total per unit: $19,960
- Total for 6 units: $119,760
Estimero totals everything by unit and by building automatically—so you’re never guessing.
💸 Save Money with Batch Upgrades
Per-unit budgets don’t mean per-unit inefficiency.
When you're doing multiple units:
- Use one labor crew for all units = lower per-unit labor cost
- Buy materials in bulk
- Schedule inspections in batches
- Use standardized layouts to cut install time
📉 Estimero lets you scale line items across units with discounts or phased delivery schedules.
🚫 Avoid These Common Budget Pitfalls
- ❌ Underestimating labor repeat costs for staggered projects
- ❌ Forgetting permit and inspection fees per unit
- ❌ Over-upgrading for the rent market
- ❌ Forgetting vacancy loss during construction
- ❌ Skipping the contingency fund
🧠 Rule of thumb: Always add 10–15% buffer per unit, especially in older buildings.
🏡 Best ROI Rental Upgrades (By Unit)
Not all upgrades return the same rent bump. Here's what works best:
| Upgrade | Avg Rent Increase | ROI (Avg) |
|---|---|---|
| New kitchen (mid-range) | +$100–$250/mo | High (3–5 yrs) |
| Updated bath | +$50–$150/mo | Medium |
| LVP flooring | +$50–$100/mo | High (durability) |
| Mini-split HVAC | +$75–$150/mo | High (adds comfort) |
| New appliances | +$50–$100/mo | Medium |
🔑 Want to maximize rent? Focus on kitchen appeal, air conditioning, and clean, durable finishes.
FAQs: Per-Unit Budgeting for Rental Properties
Q: Should I renovate all units at once or stagger over time?
A: It depends on cash flow and tenant leases. All at once is more efficient, but staggered upgrades reduce vacancy costs.
Q: Can I adjust scopes per unit in Estimero?
A: Yes! You can create variations by unit—Unit A may need new flooring, while Unit B does not.
Q: What’s a good total budget per unit for a light upgrade?
A: In 2025, $15K–$25K per unit is typical for a mid-range refresh.
