Buying an apartment/ condo?

How realistic is it to want to buy an apartment in NYC? I was thinking about this because I don’t wanna keep moving everytime my rent goes up and I eventually just want something I can call my own. Here are my stats: I would want to buy something in Brooklyn I’m single and have been renting alone I make ~120k base and sales commissions put me around $170k a year Since it’s just me a 1bd is fine I would be considered a 1st time homebuyer.

What would be a few things I could expect or is there a preferred threshold that would put me in a more comfortable buying territory or should I keep renting?
