If you make $100,000 a year, how much house you can afford depends on several factors, including your savings, current expenses, credit score, length of employment, and interest rates. However, most experts recommend sticking to the 28% rule, which states that you should spend no more than 28% of your income on your housing expenses, and no more than 36% on total debt. According to PropertyClub, with a $100K salary, you can afford a house ranging from $350,000 to $500,000 if you stick to the 28% rule. The Mortgage Reports suggests that if your annual salary is $100,000, the 30% rule means you should spend around $2,500 per month on your house payment. Keep in mind that these are just ballpark estimates, and your rate can vary greatly depending on your debt, employment history, and other factors. Ultimately, your budget and financial situation will determine how much house you can afford on a $100K salary.
