There are 3 ways to inform Concord that you have paid your taxes:
1. E-mail/scan a copy to Socorro in the HOA office. firstname.lastname@example.org
2. Mail a copy to Socorro.
HOA El Dorado/La Ventana
PO Box 9011 PMB 255
Calexico, CA 92232
3. E-mail/scan a copy to Christia at Concord. ChristiaBurge@concordservicing.com
Concord is responsible for collecting property taxes for much of the ranch. I recommend you pay locally or on line. It is much less expensive.
I am not looking for discussion here just supplying information.
