The capitalization rate (cap rate) is the ratio between the net operating income produced by a property and the original price you paid, expressed as a percentage. Does that sound a little complicated? Don’t worry let’s dig in and I’ll keep it real world and simple.
Assume you buy a $100,000 property renting for $1,000 per month
Let’s assume you are looking at an investment property with a purchase price of $100,000. You’ll have some purchasing costs like an inspection report and title insurance but lets keep it simple and assume a total cash investment of $100,000. This property is rented for $1,000 per month so we know your projected rental income.
Estimate your expenses
Let’s look at this property’s expenses broken down into a monthly view. The annual property tax is $1,000 (verified online with local county records) and is budgeted at $80 per month. Your landlord annual insurance premium is $550 for dwelling coverage and personal liability, and is a $45 per month expense. Your property manager charges 10% of gross rent received, so that’s $100 per month. Lets assume $50 per month for repairs and one month a year for a vacancy rate say $80 per month. So that’s $355 per month.
Calculating Your Net Operating Income
So now that we have your projected income and expenses we can calculate your Net Operating Income (NOI). Your income is $1,000 per month and expenses are $355 so your Net Operating Income is $645 per month and $7,740 per year. Cap rates measure the annual net operating income produced by a property as a percentage of the original price paid. In this case it’s $7,740 divided by $100,000, which is a 7.7% return.
