Step 1
Mortgage Strategy: Pay Less Interest or Keep More Cash?
The bank wants you to stay in debt forever. Here is the math to escape or leverage it smartly.
MATH TRUTH: A 15-year mortgage saves massive interest but kills cash flow. A 30-year mortgage offers safety and flexibility.
Strategy: Take the 30-year for safety, but pay it like a 15-year to save interest.
Alert: Buying “Points” is only worth it if you keep the loan for 6+ years. See ART 502.

| Strategy | Monthly P&I | Total Interest | Risk Level |
|---|---|---|---|
| 30-Year Fixed | Lower ($) | High ($$$) | Low (Safe) |
| 15-Year Fixed | High ($$$) | Low ($) | High (Tight Cash) |
| Buying Points | Slightly Lower | Break-even in ~6 yrs | Medium |

Tax Hacks & Traps: The Truth About Deductions
“It’s a tax write-off!” is the most dangerous phrase in real estate. Most people can’t claim it.
REALITY CHECK: Since the Standard Deduction is high (~$29k for couples), most homeowners gain ZERO benefit from itemizing mortgage interest or property taxes.
SALT Cap Warning: You can only deduct up to $10,000 of state/local taxes combined.

The Deductibility Rules
- Mortgage Interest: Deductible only if you Itemize.
- HELOC Interest: Deductible ONLY if used to “Buy, Build, or Improve” the home. (Car/Debt payoff = Not Deductible).
- SALT Cap: Max $10k (Property Tax + Income Tax).
Audit Traps
- HELOC Tracing Rules
- Standard Deduction Trap
- Rent vs Personal Use

Step 3
Exit Strategy: Selling for Maximum Net Profit
The goal is not just a high sale price. It’s the “Net Proceeds” after fees and taxes.
THE GOLDEN RULE: Section 121 Exclusion. If you lived in the home for 2 of the last 5 years, you can exclude up to $500k (couples) of capital gains from taxes. It’s the biggest tax break for normal people.
Don’t sell before the 2-year mark unless you qualify for an exception.

| Sale Factor | Impact on Cash |
|---|---|
| Sale Price | Gross Revenue |
| Agent Fees (5-6%) | Major Expense |
| Capital Gains Tax | $0 (if Sec 121 applies) |
| Net Proceeds | Actual Wealth |
