The site acquisition agent who contacts you, more often than not, gets paid on a milestone basis, meaning that they get paid when they perform certain tasks, such as the identification of three candidate sites, and also when leases are signed. Thus, they are motivated to move quickly because they don't get paid until they do. If you take too long, they will likely move to the next candidate. Our suggestion is that you contact them immediately, and try to proceed quickly, whether that means negotiating the lease yourself, going to an attorney (likewww.celltowerattorney.com), or retaining a consultant, like Steel in the Air, Inc. Delaying, in most cases, will mean that someone else will end up receiving the rental income. Feel free to contact us at any point in the process. We will happily advise you on what your next steps should be, whether they are to retain us immediately or to wait until the carrier has presented a formal offer.
