Buying my first home and overwhelmed.

I am a 33 year old, single guy about to try and buy a house in Buffalo area (Lancaster, Depew, Amherst, Cheektowaga maybe, Williamsville are top choices but really anywhere.) My income is $120k yearly and I've got about $30k in money saved for buying a home. (Ive been told this isn't a lot.) I've been renting my apartment for about six years and I am sick of my money just disappearing and not appreciating. Hence, my effort to buy a house.

I was pre-approved for 315k through Hunt and told my income is too high for any first-time homebuyers programs in NY. I am admittedly incredibly uneducated about buying houses but I figure I'd ask advice here on anything that may be of help to research as I'm looking at houses. Should I be looking multiple lenders or is it pretty much the same no matter where you go?

Anything helps.

Tldr: Buying first house in Buffalo area and overwhelmed. Help?!
