What does this mean?

A vacancy rate of 7–12% is above average. This could indicate a soft rental market, above-market rents, or properties that need updates. Investigate whether rent adjustments or improvements could reduce turnover.

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. South Dakota averages around 7.6%. Your actual rate depends on local market conditions, property condition, and management quality.
