You can extend serial communications via a TCP/IP network using
Lantronix device servers:

www.lantronix.com/device-networking/external-device-servers/uds1100.html

Using these will allow you to have a standard computer network over all
the property and have it carry serial data over the same network.

Unless there is a lot of automation to be done my inclination would be
to use one Elk M1 located at the main residence and have RS485 bus
devices at both of the outbuildings. This should require 4 Lantronix
device servers. It might be possible to do it with 3 but I am not sure
if one device server can handle two virtual serial connections.
