The decisions you make about where you live after graduation will shape your finances for the next decade. Start modeling them now — while the stakes are still hypothetical.
By the time you walk across that graduation stage, you'll have somewhere between 12 and 24 months before a major housing decision lands on your plate — whether that's your first apartment, a dorm, a move back home, or buying somewhere with a partner or friends. The difference between a $1,400/mo solo apartment and a $700/mo shared room compounds into roughly $8,400 saved per year. Over four years, that's a down payment on your first home.
This isn't abstract textbook finance or "start investing immediately." This is the real math of the next apartment, the next lease, and the first home. Run the scenarios below with different numbers, share the results with classmates, and walk into graduation knowing what things actually cost.
No sign-up. No accounts. Just open a scenario, plug in your numbers, and see what the math says.
Scenario A
Compare a solo apartment with shared housing. See how much you'd save every month, how much you'd have after one year, and how fast those savings could become a down payment on a starter home.
Scenario B
Model what you could actually afford on an entry-level salary. See the full monthly cost — mortgage, taxes, insurance, maintenance — and understand the hidden side of homeownership that listing sites never show.
Scenario C
What if your first home came with a built-in paycheck? Model buying a small property and renting out a room to a roommate. See how it could cut your effective housing cost to a fraction of what renting would be.
These scenarios are designed for collaborative classroom exercises. Because IntelliTC requires no sign-ups, no accounts, and no admin approvals, teachers can run a live scenario in the next class period. Pair students up, assign different cities or income levels, and have them present their results.
Compare the financial impact of living solo versus splitting housing with roommates. The savings don't just sit in a bank account — they compound into a real down payment surprisingly fast.

What does it actually take to buy a first home? This models the full cost of ownership — not just mortgage — so you see the taxes, insurance, and maintenance that never show up on listing sites. Uses the industry-standard 28% front-end DTI rule.
Entry-level salary after graduation
Cash available at closing
30-year fixed rate, typical first-time buyer
Student loans, car payment, credit cards
What you want to buy — starter home in most markets is $200K–$275K
Educational purposes only. Property tax, insurance, and maintenance costs vary significantly by state and property. PMI, closing costs, and HOA fees are not fully captured. Use this as a starting framework, not a financing decision.
House-hacking means buying a property and renting out part of it — a spare bedroom, a basement, a garage apartment — to cover a big chunk of your mortgage. This is one of the most powerful wealth-building moves available to someone in their early 20s. Let's see the math.
