I would definitely seek the help of a tax attorney or accountant... went to the govt website which directed to
this website.
It states "The following applies to the 3 product categories below:
Tax Credit:30% of cost with no upper limitExpires:December 31, 2016Details:Existing homes & new construction qualify. Both principal residences and second homes qualify. Rentals do not qualify."
When you click on the "principle residences" link it states "What is a "principal residence?"
The tax credit for energy efficiency is available for improvements made to a home that you own and use as your "principal residence." This is the home where you live most of the time. A temporary absence due to special circumstances, such as illness, education, business, military service, or vacation will not change your principal residence.
The home must be in the United States. It can include a house, houseboat, mobile home, cooperative apartment, condominium, and a manufactured home.
----------------------------------------------------------------------------------------------------------------------------------------------------
The law (Section 25C(c)(1)(A)) specifies: such component is installed in or on a dwelling unit located in the United States and owned and used by the taxpayer as the taxpayer's principal residence"
I would definitely seek legal hepl with them using the terms dwelling and what signifies a "mobile home". My thoughts are that a dwelling is a home structure and that a mobile home is not an RV. But that's just how I would interpret it.
I agree with n7bsn...
