Cap Rate is how investors value a property’s income.
Here’s the formula:
Property Value = Net Operating Income (NOI) ÷ Cap Rate
So if we increase your NOI by saving you $10,000/year and your cap rate is 6%...
👉 That adds $166,667 in value to your property ($10,000 ÷ 0.06).
That’s why even small water savings = big upside.
