First-Time Homebuyers: The Johnson Family
Young couple with $85,000 combined income seeking their first home
Key Details
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

Key Details
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

Key Details
The Challenge

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.

Key Insights
- •Low 3.75% mortgage rate favored investment strategy
- •Tax-advantaged accounts (401k) were prioritized first
- •Emergency fund was already well-established

Key Details
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.

Key Details
The Challenge
The Thompsons wanted to access equity for renovations while also consolidating high-interest debt, but were concerned about increasing their mortgage balance.
Our Solution
We analyzed the cash-out refinance benefits: lower mortgage rate, debt consolidation savings, and the value-add of renovations to their home.
The Outcome
Despite a larger loan balance, their total monthly payments decreased by $340 due to lower rates and debt consolidation. Renovations added estimated $60,000 in home value.
Key Insights

The Outcome
They adjusted to a $350,000 target, achieving a comfortable 35% DTI and maintaining healthy cash flow for retirement savings and emergencies.
Key Insights
