Q: What is a good vacancy rate for rental properties?

A good vacancy rate for single-family rentals is 5–8% annually, which equates to roughly 3–4 weeks of vacancy per year. Multi-family properties typically target 5–7%. Class A properties in high-demand markets often achieve 2–4% vacancy. Anything above 10% indicates either below-market rents, property condition issues, or weak local demand. The national average vacancy rate for rentals is approximately 6–7%.

Q: How do you calculate vacancy rate?

Vacancy rate = (Vacant units ÷ Total units) × 100. For time-based calculation: Vacancy rate = (Vacant days ÷ Total available days) × 100. Example: A property is vacant for 30 days in a 365-day year. Vacancy rate = (30 ÷ 365) × 100 = 8.2%. To calculate annual vacancy cost: Gross annual rent × Vacancy rate. At $1,500/month ($18,000/year) with 8.2% vacancy: $18,000 × 0.082 = $1,476 annual vacancy loss.

Q: How does vacancy affect cash flow?

Vacancy directly reduces effective gross income (EGI). EGI = Gross rental income − Vacancy loss − Credit losses. A 10% vacancy on a $2,000/month rental means $2,400/year in lost revenue. When running cash flow projections, always use realistic vacancy rates (5–10%) rather than 0% occupancy, which overstates actual returns. Professional appraisers and lenders always apply a vacancy factor when underwriting rental properties.
