If three years have elapsed from the time you no longer lived in the co-op to the date you purchase your apartment, then the fact that you have an ownership interest in the co-op will not disqualify you from the credit.

You are going to need very good documentation that three years have elapsed. The IRS will see you are on the 1098 for the co-op and possibly ask for proof that you qualify for the credit.

The deadline for purchasing a home eligible for the credit is November 30, 2009.

You could be on a hundred mortgages and/or deeds and still qualify but if you owned any share in what was your principal residence anytime in the three years prior to the purchase of a new principal residence you do not qualify for the FTHBC.

I’m afraid not. You are on the mortgage. This disqualifies you.

No, as you are co-owner and you used the co-op as your principal residence within the last 3 years.
