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.
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.
What vacancy rate should you use? Most lenders underwrite 5-8% for stabilized multifamily. Montana averages around 4.2%. Your actual rate depends on local market conditions, property condition, and management quality.
