First-Time Homebuyers: The Johnson Family

Young couple with $85,000 combined income seeking their first home

Affordability

Key Details

income:$85,000 annual combined income
savings:$25,000 available for down payment
debts:$450 monthly car payment, $200 student loans
location:Austin, TX area

The Challenge

The Johnsons were unsure how much house they could afford and whether to put down 5%, 10%, or 20%. They were concerned about PMI costs and wanted to understand the trade-offs.

Our Solution

Using our affordability calculator, we analyzed their 32% DTI ratio and determined they could afford a home up to $285,000 with a 10% down payment ($28,500), keeping monthly housing costs around $1,900 including PMI.

The Outcome

The family found a $275,000 home, kept their housing costs at 27% of income, and maintained an emergency fund. They plan to remove PMI in 3-4 years through payments and appreciation.

Key Insights

  • DTI ratio of 32% left room for unexpected expenses
  • 10% down payment avoided depleting all savings
  • PMI cost of $145/month was acceptable given their timeline
  • Total monthly payment of $1,885 fit comfortably in their budget

Refinancing Decision: The Martinez Portfolio

Homeowner with $420,000 mortgage at 6.5% considering refinancing to 5.25%

Refinancing

Key Details

current Loan:$420,000 balance at 6.5% (23 years remaining)
new Rate:5.25% 30-year fixed rate available
closing Costs:$8,500 estimated closing costs
home Value:$550,000 current appraised value

The Challenge

Mr. Martinez wanted to know if refinancing made sense given the closing costs and whether to take a 30-year or 15-year term.

Our Solution

Our refinance calculator showed the break-even point at 18 months. We compared both 30-year and 15-year options, analyzing monthly payment changes and total interest savings.

The Outcome

Martinez chose the 30-year refi, reducing payments by $485/month. Break-even in 17.5 months with $58,200 in total interest savings over the loan term.

Key Insights

  • Monthly savings of $485 improved cash flow significantly
  • Break-even point of 17.5 months was acceptable for his 10+ year timeline
  • 15-year option would have increased payments by $200/month
  • Total interest savings of $58,200 justified the closing costs

Investment vs. Payoff: The Chen Strategy

High-income couple deciding between paying off mortgage early or investing

Investment Decision

Key Details

surplus:$3,000 monthly available for extra payments or investing
investments:$150,000 in 401(k)s, $75,000 in taxable accounts
risk Profile:Moderate to aggressive investors

The Challenge

The Chens weren't sure whether to pay off their relatively low-interest mortgage or continue investing in their diversified portfolio.

Our Solution

We modeled both scenarios: early payoff in 6.5 years vs. continued investing. Analysis considered their tax bracket, expected returns, and risk tolerance.

The Outcome

They chose to continue investing, projecting $127,000 higher net worth after 18 years compared to early payoff, while maintaining portfolio diversification.

Key Insights

  • Low 3.75% mortgage rate favored investment strategy

offer2:Bank B: 6.50% 30-year, $4,200 closing costs
offer3:Credit Union: 6.25% 30-year, $3,800 closing costs

The Challenge

Ms. Williams received three offers with different rates and costs. She needed to understand which provided the best long-term value.

Our Solution

Our offer comparison tool calculated monthly payments, total interest, and break-even points for the higher-cost loans with lower rates.

The Outcome

The credit union offer proved best despite higher closing costs, saving $28,400 in total interest over 30 years compared to Bank A.

Key Insights

  • Lowest rate (6.25%) overcame higher closing costs over time
  • Monthly payment difference of $78 between highest and lowest rates

The Challenge
