20% cost of my home was financed thru personal installment loan. is the interest tax deductible?

Clement Viscarro: 1

Jude Kennelly: By definition a personal loan is not secured by anything but your signature. If that is the case, the interest on it is NOT deductible. If the 20% loan is actually a mortgage loan, i.e. it is secured by the property, then it would be deductible.
