My company works on large single family subdivisions. There may be 500+ lots in a subdivision. Are we required to send individual 20 day prelims for each lot or may we send one prelim for each parcel/subdivision as long as we list the lot numbers, location and price? Each lot is priced the same. Each of my contracts cover the entire subdivision. Thank you for your help! Pam Hazen phazen7@gmail.com
