37yo with $100K in savings, should I be buying index funds in this dip, and how?

I’m 37yo, married, stable careers, $220k+ household income in Texas, no debt. I have $100k in savings we’ve been sitting on for over a year to upgrade to a new house, finally decided we’re just not going to overpay for a house right now. Also have $50k in emergency funds. 15% 401k contributions, IRA, etc..

I have zero experience in stocks but it seems that this is a solid time to invest in the dip. Should I just find a local financial advisor to help me navigate how to invest in this? I don’t know where to start.
