I almost wonder if this question is a plant of some sort just to gauge the types of responses it would generate, so I'll take the bait in the even that this is a bot or troll (full disclosure, my career is not in any way related to the success or failure of the RE market). The math on this is simple as others have alluded to. I'll break it out for you.
Gross Salary: $80,000/year
Gross Salary per month: $6,667/month
After Tax Salary per month (not including 401k investing (which you should be doing, but I get this is a real estate message board and this concept is not popular): $5,434
Purchase Price: $600,000
Interest Rate per Calculator: 6.941%
Downpayment: 5% or $30,000
Financed Amount: $570,000
Mortgage: $3,769.67
Property Tax: $600
Insurance: $125
Other Costs (per calculator): $333.33
Total Monthly Payment: $4,828/month
After Tax Salary - Your New Homes Cost = $5,434 - $4,828 = $606
CONGRATULATIONS, you are what is referred to as "house poor." You have $606 after tax dollars to spend on the rest of life's expenses, including investing, buying flowers for your significant other, cell phone bill, water/electric/vehicle expense/food/childcare/hair cuts/vacation. But don't worry, in 15-20 years salary appreciation at a modest rate of 2-3% will give you an extra grand give or take while you get to look at all that property appreciation taking place as more $80K salaried workers like yourself who are told to "buy now" driving up prices from $600K to $700K to $800K, maybe even a million! Eroding ALL of their marginal income after housing costs, all for the sake of being told to "get in now." A couple of points:
1) Do not listen to a commission based RE agent or mortgage broker who recommends that you spend more of your income on housing compared to what is financially responsible for you to do. What "is" financially responsible is easily accessible to find, as is the simple math performed above. We are seeing more and more horror stories pop up from folks losing their investments after pooring them into trash syndicate deals, or buying in C/D grade areas out of state because a YT video or message board post gave them FOMO. This will correct over time as more get burned, but until then, spend responsibly.
2) Do not listen to any advice recommending that you enter into a THIRTY YEAR agreement with a bank where you pay them a monthly payment in exchange for primary residence shelter where the only way you can meet the obligations for such a contract over the lifetime of such contract is that you househack, renting out your bedrooms to likely...strangers...until you are dang near Medicare eligible. That sounds like a prison sentence, not a financial freedom plan. Many, including Scott Trench believe rent vs mortgage payments won't rebalance out for another 12-15 years (based on the last podcast they did...so agents and broker amigos and amigas, don't yell at me, I"m not the only one saying this), so let me ask you this, do you want to live in a house hacking prison for the next 15 years in order to boost your equity position on your way to financial freedom? I think not. And that didn't seem to be the original intent of this platform's messaging 6-7-8 years go. Any RE agent advising to you that this is an option that you should exercise in order to better afford a home should have their RE license revoked for violating their fiduciary responsibility to you as a client. Please report them as it benefits society at large.
