Are you sure you want to file separately? Filing a joint return results in a lower tax bill for most married couples. One of the biggest disadvantages of filing separately is that, if one spouse itemizes, the other must itemize too - even if their standard deduction would be much greater.
Rent and rental expenses are not deductible on a federal return. Some states offer a renter's credit. If your state is one of those, you'll be asked about it in the TurboTax interview on your state return.
The only deductible expenses with a new home purchase are mortgage interest, property taxes, mortgage insurance premiums (if any), and points (if any). Your husband can deduct the portion that he actually paid.
