good luck with working things out
Best of Luck,
Even though there are only 2 units in a condex, you are still a part of a condo association, so if the other unit doesn't pay their half of the master insurance, you will also be liable since there is 1 bill split in half by both sides. If only half the bill is paid, the insurance provider won't insure half of the building! So you would have to pay for the other half, then try to get payment from the other owners.
Even if you don't get paid by the other owners right away, you eventually will because they cannot sell their unit or refinance if they have any outstanding bills (such as unpaid master insurance) so one day they will be caught up.
There are some downsides to buying a condo, but in the Haverhill area it's a great, affordable way to own your own home ! I specialize in Haverhill and the surrounding towns - iIf you're in the market I'd love to assist you with your search, please feel free to call or email me any time !

In your case it is more important that the master insurance gets paid in full. Not paying the taxes could only effect your neighbors property. You should reveiw your master deed/rules and regulations to find the exact way to handle the situation. If you are having trouble understanding them, consult a real estate attorney for advice.
