receiving a house as a gift...

[Rene Bee]

Hello, 

My mom received a house through an inheritance last year.  She now wants to transfer that house to me as a gift.

What kind of  tax issues should I be concerned with in terms of receiving such a gift.  The house is in bad shape and we have gut renovated it but havent started the rehab yet.  Should I get it appraised before starting the gut?  What kind of professional should I speak to for advice. 

Thx!
