Can I buy appliances for my rental house before the house finish construction? (Tax deduction purpose)

I have a rental house under construction and will be closed in February 2018. I am thinking to take advantage of Black Friday to get some appliances for the house. If I buy these appliances now(November 17), keep them for a few months, Can I still choose to depreciate them in the future after they place in service in 2018? Please advise. Thanks!
