I currently live and work in NJ. I am single and live with my parents. The apartment we currently live in is small and I want to buy a house, but my state is pretty expensive.
My parents found a nice house in MD but it is about 140 miles away from my office. My plan is to have my parents live in this house and I plan on "living" in both the MD house and my apartment in NJ. I can work from home one day a week, so I will be in MD Friday to Sunday, and in NJ Monday to Thursday.
Now supposing I claim that MD home as my "primary residence" to get the best rates on a mortgage and for taxes, I would change my driving license and voter registration to that state. Would that be considered "fraud" or "illegal"?
I do live there, just not all the time, maybe 35% of my time.
I can't seem to find any legal defintion of a "primary residence", Wikipedia says "Criteria for a primary residence consist mostly of guidelines rather than hard rules, and residential status is often determined on a case-by-case basis."
