House ownership dispute
​
I'm looking for objective opinions on a family property dispute.
There are two houses:
House A (where I live): I live there with my wife and child. The house title is under my father's name. The housing loan is entirely under my name, and I pay all the installments. My father refinanced the house using my name . Hence the loan in my name .
House B (where my parents and siblings live): The house title is under my name. The housing loan is also under my name. My brothers are supposed to pay the monthly installments, but because the loan is legally mine, if they pay late I have to cover the payment first to avoid damaging my credit score. They reimburse me later, but I carry all the legal and financial risk.
When both houses were purchased, I was the only one eligible for the loans, so everything was put under my name.
My issue is that because both loans were under my name, I lost the opportunity to buy another property 5+ years ago when prices were much lower. Today, property prices have nearly doubled.
When I raised this with my parents, they kept saying: "You're the eldest, so you should take care of the family." "You're capable. You have a good job."
I replied that my capability isn't the issue. I accepted all the financial liability and risk, and because of that I lost a major investment opportunity.
I then asked for House B to remain legally under my name (it already is), while they continue living there. They refused because they said they live there.
I also pointed out that House A, which I pay for, is under my father's name and they intend to divide it equally among all four siblings in the future. That feels unfair to me.
When I said I would seek legal advice to protect my interests, my parents replied, "If you do this, our relationship is over."
Am I being unreasonable for wanting to protect my legal and financial interests after carrying the liability for both houses for years? Or am I looking at this the wrong way?
