CURRENTLY OWN TWO DUPLEX , WE ARE HOUSE HACKING ONE OF OUR DUPLEX , WE HAVE OVER 300K IN EQUITY !

If your goal is to offset your mortgage with a house hack then Lowell would be a good bet, but if you're looking for a longer term appreciation play then the areas closer to the city would be better, although the offset from cashflow may be lower than what you're looking for.A good step for you would be to dig into specific areas more as @Lien Vuong noted above.

Where you planning to house hack? 

When you say your house hack phase has passed, are you saying you DON'T plan to occupy a unit of the 4-plex?

House-hacking in a multi-family unit is one strategy I wish I had been aware of when I chose to purchase my first property.

I currently House Hack in Everett, WA (near Seattle) and utilize FurnishedFinder for our basement ADU with great success.

Most properties they have to bush hack up and down hills and through jungle.  

Congrats on the house hack, Keith!

Since you are already familiar with house hacking, I would consider converting your current home into a rent-by-room or whatever it takes to keep it as a long-term rental, then look for another home you can hack.

Hi all, I've been housing hacking a duplex since 2021 and due to some life changes will be relocating out of state.
