The average occupancy time for tenants is usually 3.5-4 years; average leasing time is 18 to 21 days. If you take a four-year occupancy and round up a 21-day leasing time to one month (30 days), that calculates out at 2% vacancy. We're consistently between that 2-4% vacancy. So while these numbers are not guaranteed, we do track them to have a good idea of how we expect our rental properties to perform. This also allows you to see that there is a justification for the numbers we input in our pro forma. These percentages for vacancy, maintenance, etc. are not just arbitrary numbers. It should also be noted that as you acquire multiple rental properties, you will likely will see a lot more stability in your percentages. Ideally those numbers will reduce with the more properties you own. That is why, for sustainability, it is vitally important to have a well-diversified portfolio of multiple streams of income with multiple properties in different locations.
