Without predictability on insurability and risk of the primary collateral being destroyed (which at this point theoretically could happen anywhere) as it’s January, and would you believe in 2023 that 71K thousand square miles of northern Canada burned 5% of the entire Canadian forest with billions in damages? 

My biggest concern with house hacking is giving up my primary residence.

Kind of hard to see why you would not want to press this button and try to pay it down/off as soon as possible, if it's your primary home.It's very unlikely you'll regret purchasing a primary residence in Boston if the market rallies, and if the market downturns.

Lenders stopped allowing rent by the room due to modifications done to the property resulting in functional obsolescence and significant cost to cure in the event there was a default and they needed to foreclose on the home and resell it, given that the main buyer pool for single-family homes are primary occupants.
