Should you buy this year?
Can you buy? Maybe. Check with a good mortgage broker.
But your question was SHOULD you buy. Your husband has poor credit. You have weak credit and no work history with your new job--though your job (nurse) is in high demand. You have very little in savings. If you don't want to stay in the apartment you're currently in, that's fine. Move to another rental apartment. Work on cleaning up your husband's credit score and on strengthening yours. Build up your savings. Wait. Then buy when you're better positioned to do so.
Hope that helps.
