About the experience
What Is This House Affordability Challenge?
This house affordability challenge is an interactive financial simulation, built for anyone who has typed “how much house can I afford” into a search bar and gotten back the same plug-and-solve mortgage calculator. Here, you start with a fixed U.S. scenario and make a sequence of home-buying decisions, then watch the simulated 12 months that follow.
The core mechanic
How the House Affordability Challenge Works
Eight decisions run in sequence: down payment, loan term, rate vs. points, cash vs. financed closing costs, ownership costs, an unplanned repair, an income/expense shock, and a year-end bonus. Each choice recalculates your loan balance, monthly housing cost, and cash position — then the simulation reports what changed. It does not tell you which option to pick.
Search intent
How Much House Can I Afford? Try the Challenge Instead
A traditional mortgage affordability calculator takes your income, debts, down payment, and rate, and returns a single estimated price range. This challenge starts from a fixed $340,000 house and tests how that purchase actually behaves once down-payment size, points, closing costs, ownership costs, a repair, and an income dip enter the picture. The output isn’t a bigger or smaller number — it’s a simulated housing-cost ratio and a resilience read on your cash position across the year.
How to play
How to Use This House Affordability Challenge
- Start with the scenario shown above.
- Choose an option at each decision point.
- Read “What Changed?” before moving on.
- Continue through all eight decisions.
- Replay the challenge to compare a different timeline.

Scenario setup
USA Assumptions Used in This Simulation
| Assumption | Simulation value | Role |
|---|---|---|
| Country | United States | Scenario context |
| Home price | $340,000 | Starting purchase price |
| Household gross income | $95,000 / year | Used for the housing-cost ratio |
| Simulated monthly take-home cash inflow | $6,300 | Fixed simulation assumption — not derived from the $95,000 gross figure |
| Starting savings | $68,000 | Opening cash balance |
| Baseline monthly expenses | $3,400 | Non-housing recurring expenses |
| Simulation mortgage rate | 6.75% fixed (before points) | Illustrative financing assumption, not a current market rate |
| Simulated PMI (below 20% down) | $185 / month, applied for the full simulated year | Illustrative PMI assumption — simplified; see FAQ |
| Base simulation period | 12 months | Challenge horizon |
| Scenario alert | Cash below $5,000 | Game-state flag, not a universal benchmark |
Illustrative values are used where the simulation needs a fixed scenario. They are not presented as a forecast of what every U.S. buyer will qualify for.
Method
How the Calculations Work
Fixed-rate mortgage payments use the standard amortization formula. Choosing discount points lowers the simulated rate and is paid in cash at closing, alongside a separate base closing-cost charge you can pay from cash or finance into the loan — each choice recalculates the starting loan balance and payment. The simulation tracks cash, PMI, ownership costs, and the remaining loan balance across the simulated year, including an estimate of future interest saved if you apply the year-end bonus to principal.
Research
Sources and Methodology
The financing model is designed around standard fixed-rate mortgage mathematics and U.S. consumer-finance terminology. Public guidance from the Consumer Financial Protection Bureau is used for concepts such as PMI, discount points, closing costs, and debt-to-income considerations. Rate context is informed by Freddie Mac’s published mortgage market survey.

Common questions
FAQ
Is this a house affordability challenge or a calculator?
It’s an interactive simulation, not a static calculator. Instead of one affordability number, you make decisions and see what changes across the simulated year — the same “how much house can I afford” question, answered as a story instead of a single output.
Is the 6.75% rate a current U.S. average?
No. It’s an illustrative fixed assumption used to keep the scenario consistent, and it’s the rate before any points are purchased. Actual mortgage rates vary by borrower, lender, credit profile, loan program, and term.
Do discount points actually lower the rate in this simulation?
Yes. Buying 1 or 2 points lowers the simulated rate and increases the upfront cash paid at closing; the simulation shows the resulting monthly savings and an estimated breakeven period. Real-world point pricing and rate reductions vary by lender and loan program.
Why does a down payment under 20% add PMI, and does it ever go away?
Lenders commonly require PMI on conventional loans when the down payment is below 20%. For simplicity, this 12-month simulation applies PMI for the entire simulated year. In reality, PMI can typically be requested for cancellation once the loan balance reaches 80% of the home’s original value (with conditions), and it generally terminates automatically at 78% for a current borrower — thresholds a 12-month simulation usually won’t reach.
What counts toward the housing-cost ratio?
The simulation adds principal and interest, PMI, and the selected ownership-cost package, then divides by the scenario’s gross monthly income. It’s shown as a simulated output, not an approval threshold — actual underwriting considers other debts, credit, reserves, and loan-program rules.
Does the game tell me what I should choose?
No. The experience shows the simulated consequences of your choices without issuing a personalized recommendation.
Can I replay the challenge?
Yes. “Draft Another Blueprint” resets the simulation so you can compare a different sequence of decisions.
