Scenario 2: By Luke Embry Hour 3 (Colwell)

Harper earns $4,083.33 a month

Harper earns 70,000 dollars a year, and after the 30% tax cut she is left with $49,000 for her total annual salary.

Harper's Student Loan Payment is $402.78 Monthly

Because Harper went to college, she has a student loan of $35,000. The loan must be paid within 10 years, requiring 120 payments from her. So, if the interest rate is 6.8%, her payment would be $402.78 per month.

Car Payment

Harper also has a payment to make towards her Car for $325 a month.

Costs of Living

Harper also has money that needs to go towards food and other necessities. If she spends around $400 a month on food and $200 dollars a month on other groceries, her cost of living would come to about $600 a month.

Material Wealth

Obviously Harper will want to spend her money on home improvements and furniture, so she will spend an average of about $1000 dollars a month in this category.

Totaling up the Digits





-$1,000 = up to $1,755.55 a month to spend on a house.

Bank of America requires at least a 4.732% interest rate on a 30 year loan. So, Harper would be capable of buying a house at $337,240.69 or less.

An Affordable House for Harper

The house picture here is priced right around $300,000, this is within the price range Harper would be looking for.
