How do I determine a capitalization rate?
A "cap rate" is the rate by which you can capitalize or set a value for an income stream. If a property generates $100 in operating cash flow and you have determined that you would like to generate a return / capitalization rate of 10%, the value or price you might pay approximately equals $1,000 ($100 / 10%). The more stable the income stream, the lower "cap rate" you are willing to accept, and vice versa. Here are some rough guidelines for you:

Risk / Quality Residential Property
(Single: 1 unit)
Residential Property
(Multiple: 2-4 units)
Apartment Complex Commercial
High Risk 14% 12% 11% 12%
Medium Risk 12% 11% 10% 11%
Low Risk 10% 9% 8% 10%
