My husband and I currently own a half duplex in MA, that is considered a condo. We have a master deed but do not have a condo fee and split master insurance. We have the opportunity to purchase the other side of the duplex but will need to take out an investment loan initially. I believe our options after the purchase would be to dissolve the condo association and refinance into an owner occupied loan at a better rate and also have the property reassessed as a multifamily for a lower tax rate as oppose to have two condos. Has anyone had experience with this type of purchase?  We do plan to live in this property as our primary residence long term.

Any feedback would be greatly appreciated!
