No-fee 1031 exchange Qualified Intermediary that shares interest earned on your funds
Deferred charges $0 on standard forward 1031 exchanges and instead earns from the interest generated by escrowed proceeds.
Unlike most QIs that keep the interest, Deferred pays a share of the interest earned on your exchange funds back to you.
Proceeds are held in individually FDIC-insured accounts at commercial banks, with a $25M fidelity bond, $5M E&O cover and coverage options up to $175M.
Supports standard forward exchanges plus more complex reverse and improvement (build-to-suit) structures with dedicated support.
