Sorry, my answer might be wrong. I've talked to my agent regardi

and was told that it is not specifically stated that, the house you are buying must be your primary residence.

What I understand right now is that regardlss of primary or not, as long as you use the dwelling for your job, the closing cost could be reimbursed to a certain percentage.

If you are not certain, you could ask your agent to provide you a copy of your company's relocation reimbursement policy.
