Generally, all real property is "like-kind" to all other real property within the US. Like kind property is property which is not identified as your personal residence or second home, and was not acquired for resale or considered inventory or dealer property, only like kind property may be traded under the I.R.C. Section 1031 exchange rules. The property relinquished in the exchange must have been either productively used in your trade or business, or held for investment, i.e., you must have effected a "qualified use" of the property. Likewise, it must be your intention as you acquire your replacement, to either hold that property for investment or use it for a business purpose
