Hello and welcome again. Thank you for your reply.
If you have a mortgage on your name, adding another name to the tile will have some benefits as well. You need to be aware that once added to the mortgage title, the person will be legally responsible for part of the mortgage payments; he will also have claim to the home’s equity. If the person being added to the mortgage title has a good credit score, then you could qualify for a lower interest rate.
This would be certainly possible. I would advice you to remain ready with the other person's all financial documents such as tax returns, W2s, year end bank statements, etc. Then, you should contact the lender and ask for necessary formalities to be done. He will guide you through rest of the process. You can also use your real estate broker for this if you need.
The following is for your general reference.
Now coming to the will part.
I do not know which State you are currently in. So, to prepare your will, there are two ways. Just contact your State Bar Association -- Most State Bar Associations have public service for lawyers referrals. They will direct you to the person best suited for your requirements.
The second option is to use services as under. They are relatively cheaper as well.
I am sure this would help. You may please leave a positive rating if this helped or please feel absolutely free to revert back with further queries and I would be more than happy to keep assisting you.
