Separate ownership cash from economic cost
See this course’s project requirements
A fictional homebuying decision file with ownership costs, cash to close, comparable loan estimates and a closing discrepancy log.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- A rent/ownership comparison with separate cash and principal columns.
- A cash-to-close and remaining-reserve worksheet.
- An annotated loan-estimate comparison sheet.
- A points/credit cash-flow comparison with break-even and limitations.
- A closing-disclosure reconciliation and clarification log.
- A completed fictional home-finance decision file.
Review and revise
Use these criteria to check your work and choose what to improve.
- All supplied records reconcile and the decision uses the named case rules.
- Calculations show units, intermediate values and a second check.
- Changed-input practice revises the affected result and identifies uncertainty.
- The final project combines six lesson records, separates fictional assumptions from current rules, and states a supported next step.

The idea in everyday life
This is an original fictional practice case. No account, payment, personal record or outside participation is required. Monthly practice ownership: interest $800, principal $300, tax $200, insurance $100, maintenance allowance $100. Renting costs $1,200/month. Ignore price changes and purchase/sale costs in this first exercise.
Principal repayment uses cash but is not identical to interest expense; home value changes and selling costs remain separate.
Separate ownership cash from economic cost — worked practice
Principal repayment uses cash but is not identical to interest expense; home value changes and selling costs remain separate.
Use paper or a local table; label all amounts as fictional USD unless the case names another unit. Monthly practice ownership: interest $800, principal $300, tax $200, insurance $100, maintenance allowance $100. Renting costs $1,200/month. Ignore price changes and purchase/sale costs in this first exercise.

Copy as plain text
1. Step 1: Create separate cash and nonprincipal-cost columns
Create separate cash and nonprincipal-cost columns.
You should see: Five ownership components are listed.
Principal repayment uses cash but is not identical to interest expense; home value changes and selling costs remain separate.
2. Step 2: Add all ownership cash payments
Add all ownership cash payments.
You should see: 800+300+200+100+100=$1,500/month.
Keep this intermediate result so the final decision can be checked.
3. Step 3: Remove only principal for this limited cost comparison
Remove only principal for this limited cost comparison.
You should see: Nonprincipal cost $1,200/month.
Keep this intermediate result so the final decision can be checked.
4. Step 4: State what the comparison cannot conclude
State what the comparison cannot conclude.
You should see: Same nonprincipal monthly cost does not establish equal total value; price changes, transaction costs and access remain unresolved.
Keep this intermediate result so the final decision can be checked.
What to finish
A rent/ownership comparison with separate cash and principal columns.
Watch for this
Calling principal repayment free because it is not an interest expense.
How can I tell I understand it?
Distinguish a homeownership cash payment from nonprincipal cost under a limited model on the supplied changed case while preserving the stated rule and checking the final record.
