<prompt> Human: Nine years ago we decided to go in on a townhouse that may at some point become their retirement home but has always and is currently inhabited by myself, my husband and our two little ones. They paid in cash for their portion and I took out a loan for mine. The HVAC system just quit over the weekend and needs to be replaced to the tune of 8,000. Is it reasonable to ask my parents to pay 55 of the cost to replace the unit? They most definitely have the money but that is not why Im asking them to share in the costs. They are arguing that they dont reap the benefits of the house tax-wise and they dont reside at the home they shouldnt be responsible. Just looking for some sound advise.  <response>: So you parents paid for half a house, in cash, that they dont live in, that generates no income or tax benefits for them, and youre going to ask them for more money?No, its not responsible to ask your parents for a single penny.
