The net operating income (NOI) is a key term in determining the profitability of any commercial property. It implies the income coming from a property after deducting its operating expenses but before paying taxes and loan payments.

It is calculated by dividing the vacant units in a commercial property (or area) by the total units available in the property (or total area), multiplied by 100 to get a percentage.
Why is this important? Well, when the vacancy rate is high, that might mean a low market demand. That’s not always a bad sign, but it is definitely something to look for, especially if you are considering flipping the unit after some time.

On the other hand, buying the property gives you bigger space to modify it according to your needs, and adds to your future investment potential.
