Buying a house in 2017 - Taxes

[Miranda M.]

ADVISE: I made $120,000 in 2017 and was planning to buy a house to decrease taxes. My CPA told me if I buy a home now, I'll only get a tax break for Nov and Dec. Is that the case? If so, I have $100,000 in cash I can liquidate. Aside from putting $18,000 in a 401k. How else can I use that money to get tax breaks? Thanks! PS. I won't be making the $120,000 next year.
