You are delusional as fukk obviously.
#1 After taxes, health insurance, 401K and other stuff taken out you'll get about $2,600+ per paycheck as a single person with no dependents
The mortgage amount you are seeing does not include taxes and Insurance, clones. You ever bought a house, breh?
Try adding say least another $400 to $500 to that number you see in your link. Them mortgage calculators on real estate don't include Taxes and insurance. Find your own online. Put it this way a house costing half that's mortgage can cost you $1200 a month. So just imagine how much this one will.
My car payment and car insurance alone are $262 and $167 a month respectively
I have flat billing on my electric bill which is about $90+ per month. In the winter I have gas service which runs on average about $100.
Cable/internet service about $120
Now I know I overspend s lot eating out and that's my weakness. I love fine dining and when I go out to eat even alone I'm looking at about $45+ for dinner sometimes on the high end. Your grocery estimate can use some work too.
Again when I say staying afloat o didn't mean paycheck to paycheck. I mean you are able to live decent, save a bit. THAT IS NOT WHAT I CONSIDER COMFORTABLE
