Cheapest way to connect to home network when I move?

+1 for VPN

First setup that Pi as a VPN server and test connecting from local network.

Then, to reach the entire home network throught the VPN, you need to add a route. Say you use for the VPN network, then you need something like the option "push route" in your VPN server config, so that VPN clients get to know the rest of the network.

Also in your Internet router you might need to add a static route:
target network: gateway: your VPN-server IP address

Then add a port forwarding rule to your router to forward VPN traffic to your Pi

Lastly add a dynamic DNS service to connect from outside.

Sounds like much trouble, but is worth the effort in the long run!
