There are forwarding services like myrvmail.com and I know USPS will even forward mail temporarily. BUt since you won’t have an actual address for USPS to forward to and myrvmail.com might be overkill for just a few months. I’d recommend (and its what I do), is just have a family member.neighbor check the mail once a week. I have somebody come by and water plants and check the house anyways, so I just have them grab the mail too. I know that wont work for everyone, but its an idea.
