My job is shaky, want to buy a new house, have decent savings?

I need to move out since my landlord is selling the house. My rent hasn't changed but everything around me has gone up. So I want to buy. I'm looking to buy a 200-230k house and i have a little over 100k in savings. Will my savings factor into my mortgage if by any chance I get laid off before i purchase? I still have ample backup cash

Thanks
