Can you claim home mortgage interest if your name is not on the mortgage loan but you pay for it ?
No you can't, sorry about that. Your name has to be on the mortgage loan before the interest paid that year can be credited to you. Check with your real estate attorney for all the specifics.
A mortgage has names on it. When the interest is accumulated, the persons name on the mortgage, will be given credit for it. If your name isn't on the mortgage, you aren't allowed, to use that credit, on your income tax.
No its not possible. It is necessary that your name should be there before the interest rate has to be credited in your name. Check out this for your financial solutions services https://www.safebridgefinancial.com/mortgage-solutions/insurance-services/
