Good morning
There are several ways to do this, one as you said is setting up a house and using that address but then you pay for three months you are not there. this is a bit crazy.
The other way is to set up a mail forwarding account there are several places to do this.
Sweden
Thialand
Switzerland
as well as many other places.
You end up getting a P0 Box address as well as a home address
Many people do this that do not want to have a x wife find them,
There are several places to do this online for more info send me a PM
I will show you where to go for this service. I have been a exat for
16 years and have used this service 12 years saves lots of taxs in the end.
Here is also a link for a service in thialnd I have never used them and i am not sure they will forward your mail where you want it forwarded to.
PO BOX
