How the math works

Payback = upgrade ÷ (premium × occupancy). Lifetime lift = premium × occupancy × 12 × retention years.

Verify rent premium against comp set before approving the upgrade budget. Premium projections that extrapolate from comp set medians without 2-3 solid upgraded-unit comps within a mile routinely overshoot reality by 20-40% — and every dollar of premium miss stretches payback one month.

Frequently Asked Questions

Typical renovation?

Light (paint, flooring, hardware, faucets): $4-8k per unit, $75-150 rent lift. Medium (counters, appliances, lights): $8-15k, $125-250 lift. Heavy (kitchen + bath + finishes): $18-35k, $200-400 lift. Premium matches market.

Payback threshold?

24-36 months payback = strong. 36-48 months = acceptable. 48+ months = marginal. Market rent premium discipline matters more than renovation scope; over-renovation rarely gets full premium capture.

Portfolio strategy?

Phase upgrades — 15-25% of units per year aligned with turn cycle. Sequential renovations create reference units at each stage, avoids market disruption, lets management learn pricing power before full commitment.

How often should I rerun this?

Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
