What Is Home Equity?

Home equity is the portion of your home that you truly own — the difference between what your home is worth and what you still owe on your mortgage.

Home Equity = Current Home Value - Remaining Mortgage Balance

• Example: Home worth $500,000, mortgage balance $300,000 → Equity = $200,000 (40%)
• Equity grows as you: Pay down the mortgage / Home value increases / Both
• Equity decreases when: Home values drop / You take out a home equity loan / You borrow against it

How to Build Home Equity Faster

• 1. Larger down payment — More down = more equity from day one
• 2. Extra principal payments — Every extra dollar reduces the balance and the interest you pay. A $200K 30yr mortgage at 6.5%: extra $200/month pays off 9 years early and saves $73K in interest
• 3. Shorter loan term — 15-year mortgage builds equity much faster than 30-year
• 4. Home improvements — Strategic renovations (kitchen, bathrooms, curb appeal) increase market value
• 5. Market appreciation — In a rising market, your equity grows without any action from you
• 6. Biweekly payments — 26 half-payments = 13 full payments/year instead of 12. Cuts 4-7 years off a 30-year mortgage

How Much Can You Borrow?

Most lenders use an 80% CLTV (Combined Loan-to-Value) ratio:

Max Borrowable = (Home Value × CLTV%) - Mortgage Balance

• $500K home, $300K mortgage, 80% CLTV: ($500K × 0.80) - $300K = $100K max
• $500K home, $200K mortgage, 80% CLTV: ($500K × 0.80) - $200K = $200K max
• $400K home, $350K mortgage, 85% CLTV: ($400K × 0.85) - $350K = -$10K (not eligible)
• $600K home, $150K mortgage, 90% CLTV: ($600K × 0.90) - $150K = $390K max

Home Equity Loan vs HELOC: What's the Difference?

• Home equity loan: One lump-sum payment upfront, fixed interest rate, fixed monthly payment, loan paid off over set term (5-20 years). Best for: known expenses with clear amounts
• HELOC: Revolving credit line (like a credit card), variable rate, draw and repay as needed during draw period (5-10 years). Best for: ongoing projects, uncertain expenses
• Both: Use home as collateral. Interest may be tax-deductible if used for home improvements

Is Home Equity Tax Deductible?

Under current tax law (post-2017 TCJA):

• Deductible: Interest on home equity debt (HELOC or home equity loan) used to buy, build, or substantially improve the home
• NOT deductible: Interest on debt used for anything else — paying off credit cards, college tuition, vacations, investments
• Important: The deduction is limited to interest on debt up to the original loan amount (pre-2017 rules allowed up to $100K/$1M separately)
• Consult a tax advisor — tax law changes frequently, and your situation is unique

When to Tap Home Equity vs Sell

• Tap equity (keep the home): Need funds for home improvements with ROI, debt consolidation at lower rates, one major expense with clear payoff
• Sell the home: Need a different home/location, retiring and want to downsize, relocating for work, home needs more repairs than it's worth
• The math: If you can invest equity at >7% annual return and your mortgage is <6.5%, tapping equity for investment may make sense — but it concentrates your wealth in real estate and adds risk

5 Smart Uses for Home Equity

• 1. Kitchen remodel: Average ROI 60-80%. A $50K kitchen remodel on a $400K home adds $30-40K in value
• 2. Debt consolidation: Pay off 22% credit cards with 8% HELOC → save 14% annually on the balance
• 3. College tuition: CHEER within 529 plan rules; HELOC interest may be deductible if for education
• 4. Rental property down payment: Build wealth faster using existing equity to acquire more real estate
• 5. Emergency fund supplement: Only tap as absolute last resort — prioritize cash first
