What does this mean?

A 3–7% vacancy rate is the sweet spot for most rental markets. You're maintaining strong occupancy while likely pricing rents at market rate. Most lenders underwrite in this range.

Understanding Vacancy Loss

Vacancy loss is the income you don't collect when units sit empty between tenants. It's the gap between what a property could earn at full occupancy (Gross Potential Rent) and what it actually collects.

Vacancy Loss = Gross Potential Rent x Vacancy Rate

What vacancy rate should you use? Most lenders underwrite 5-8% for stabilized multifamily. Delaware averages around 3.8%. Your actual rate depends on local market conditions, property condition, and management quality.
