Answer
To calculate the leasing closing ratio, you can use the following formula:
Leasing Closing Ratio = (Number of Applications / Number of Property Tours) x 100
In your case:
Leasing Closing Ratio = (4 Applications / 16 Property Tours) x 100
= 25%
So, your leasing closing ratio is 25%. This means that 25% of the potential renters who toured the property ended up submitting an application.
