How the math works

Annual = monthly × 12 × spaces × occupancy. Yield = (revenue − opex) ÷ cost.

Roll out paid parking at lease renewal with a six-month rate hold. Mid-term impositions spike turnover and complaints; renewal rollouts convert at 70-85% take rate with rent-like anchoring built into the resident's annual review cycle.

Frequently Asked Questions

Parking monetization types?

Reserved spots: $25-75/mo (garden), $100-250 (urban). Covered/carport: $40-100 above reserved. EV charging: $30-100 plus kWh markup. Garage with attendant: $100-400. Each has setup cost and opex.

Setup costs?

Stripe + sign reserved spots: $1-3k setup, minimal opex. Carport install: $3-6k per space. EV charger (L2): $5-12k installed. Garage gate/access control: $20-60k. Match setup cost to achievable monthly revenue.

Monetization risks?

Tenant pushback (can't charge for what was free). Competitive pressure (comp properties give free). Occupancy/demand uncertainty. Phase in at lease renewal rather than mid-term to minimize friction.

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.
