The short answer is no one is absolutely sure. The CAP (capitaliztion) rate for investment properties is set by the market demand and the credit worthiness of the tenant(s)- and other things. Selecting a CAP rate (e.g. price) for an investment property is both a science and an art. CAP rate is not the IRR or a cash on cash return measure. It is a way the market has of valuing types of investment property based on market demand, quality of tenant, location, terms of the lease, and the property itself. When buying investment property, buy quality of income stream and location before you select using other measures.
