Frequently Asked Questions

What is a good vacancy rate for rental property?

5% vacancy is a common underwriting assumption for stable single-family rentals in strong markets. 8-10% is more conservative and appropriate for multifamily or markets with higher turnover. Never underwrite at 0% — every property has some vacancy over time even in tight markets.

How does vacancy affect rental cash flow?

On a $1,500/month rental, 5% vacancy costs $900/year, 8% costs $1,440/year, and 10% costs $1,800/year. Over a 10-year hold, the difference between 5% and 10% vacancy is $9,000 in lost income. Always model realistic vacancy before buying.

How do I calculate rental vacancy rate?

Vacancy rate = (vacant days ÷ total available days) × 100. If a property was vacant for 30 days in a year, vacancy rate is 30/365 = 8.2%. For underwriting, use market data on average days-on-market for rentals in your target neighborhood.

What causes high vacancy rates in rental properties?

Above-market rent pricing, poor property condition, bad location factors (school district, crime, noise), poor property management, tenant screening issues leading to high turnover, and market-level oversupply. Identifying and addressing the cause is more valuable than just modeling the cost.

How do I reduce vacancy in my rental properties?

Price at or slightly below market rents for faster leasing. Maintain the property well to retain good tenants. Screen tenants thoroughly to reduce turnover. Offer lease renewal incentives. Start marketing 60 days before current lease expiration. Build relationships with local relocation companies.

What is economic vacancy vs physical vacancy?

Physical vacancy is units that are literally empty. Economic vacancy includes physical vacancy plus rent concessions, delinquent tenants, and below-market rents. Economic vacancy gives a more accurate picture of actual income loss. Always underwrite using economic vacancy for conservative analysis.
