I am renting/buying a home from my sister.
We have it set up that the home is in her name and after the loan is paid(10 years, of which 4 is left) the title will transfer to me. (We did this because I wasn't sure if I was going to stay in the area and didn't want to have to mess with selling a home long distance.) Yes, it is in writing. At the end of the loan we had planned to do a quit claim deed and transfer it to my name.
My question is this, in executing a quit claim deed, where it is only her name on the deed, can it just be transfered to me or do I have to pay sales tax etc. (I pay the property taxes etc. now) If there has to be a price on it, does it have to be actual value or a value set by the owner ie:$10.00.

Spend some money, and take the agreement to a lawyer. The actual wording makes a difference.

You will also want to get a title search done (after the final payment) to make sure everything is legaly clear.

Government is usually very hungry for money, so don't be surprised if the sales tax is on the appraised value. Government always greedily puts itself first.
