Retirement tax questions

Thank you both for sharing your insight.  So my spouse has W2, and if I have 1099 and we file jointly, do we have $12,700 standard deductions?  Or it would be only $6,350? As 1099, Can we still deduct unreimbursed expenses directly from income on top of that $12,700?  After more analysis of my deductible job expenses, I don't think it will exceed higher than $10,000.

My job is working in a hospital/clinic/ home care. Would property home tax or rent from my apartment be consider deductible for a 1099 even though I live there and I don't necessary work there?
