This can’t be stressed enough. A real estate website must be user-tolerant. Customers should be able to reach you easily. If a customer wants to contact anybody on the website perhaps they have seen a property they are interested in : if they don’t get a response or if they cannot find the contact button, that could be the end of that sale. Any agency stands to loose customers if simple buttons cannot be located easily. Sales are lost easily if a customer does not trust the website due to small things.
