How does an old bankruptcy affect future loan applications?

In my days of unrecovered mental illness, I could not work, nor could I pay my bills. I took refuge by filing bankruptcy 15 years ago. Since then, I have rebuilt my credit and now have an excellent rating. I have obtained 2 personal loans without incident. They didn’t even ask about past bankruptcies on the applications.

I am wondering about future loan applications and specifically a home loan. Will they ask about bankruptcy, and will one that old have any bearing?
