Hello Denise-Dave Foster is correct above that 1031 exchanges are federally mandated under IRS taxcode Section 1031 and any qualified QI with a national presence should be able to handle your transaction.Several items for consideration:  choose a QI that has experience working outside a defined geographic area and has proper bonding & escrow accounts established to protect your funds.Feel free to pm me if you have additional questions.
