Whatever solution you use for your legal address could also provide a dedicated VPN and even mail scanning/forwarding. For example, renting a shared room in an apartment with 9 other roommates (one or two who live there full time), and use the premise Internet connection for a VPN server with a nice clean residential IP. Even more practical if there is an option to stay overnight occasionally, and your full-size residence is only several hours drive away. I can even see these type of arrangements arising naturally when roommates move out. Watch your MTU though!
