Secured Borrowing Guide
Borrow Against Your Home for Improvements
Your home’s equity can fund major improvement projects at rates far lower than credit cards or unsecured loans. Home equity loans, HELOCs, and cash-out refinancing let you tap this value—but your home serves as collateral. Here’s how each option works and how to choose wisely.
Secured Borrowing Basics
- Collateral: Your home secures the loan
- Rates: 7-11% (lower than unsecured)
- Max LTV: 80-85% combined with mortgage
- Tax benefit: Interest may be deductible
- Risk: Foreclosure if you default
Quick Answer
To borrow against your home, use a home equity loan (lump sum, fixed rate), HELOC (revolving credit, variable rate), or cash-out refinance (new mortgage with cash back). You’ll need 15-20% equity remaining after borrowing, credit score of 620+, and DTI under 43-50%. Rates are typically 7-11%—much lower than credit cards or personal loans—but your home is at risk if you can’t repay.
Three Ways to Borrow Against Your Home
Home Equity Loan
Lump sum at a fixed rate with predictable monthly payments. Also called a “second mortgage.”
- Rate: 7-11% fixed
- Amount: Up to 85% LTV
- Term: 5-30 years
- Funding: 2-6 weeks
Best for: Known costs
HELOC
Revolving credit line you draw from as needed, like a credit card secured by your home.
- Rate: Variable (Prime+1-2%)
- Amount: Up to 85% LTV
- Draw: 5-10 years
- Setup: 2-4 weeks
Best for: Flexibility
Cash-Out Refinance
Replace your mortgage with a larger one and receive the difference in cash.

- Funding: 30-45 days
Best for: Large amounts

How to Calculate Your Borrowing Capacity
Step 1: Know Your Home Value
Check Zillow, Redfin, or recent comps. For lending, a professional appraisal ($300-$600) determines the official value.
Example: Home value = $450,000
Step 2: Check Your Mortgage Balance
Find your current payoff amount on your latest mortgage statement or lender portal.
Example: Mortgage = $280,000
Step 3: Calculate Current Equity
Home value minus mortgage balance equals your current equity.
Example: $450K – $280K = $170,000 equity
Step 4: Calculate Available to Borrow
Multiply home value by 85%, then subtract mortgage balance.
Example: ($450K × 85%) – $280K = $102,500 available
Equity Example Calculator
If your home is worth $400,000 and you owe $250,000, your equity is $150,000. With an 85% max CLTV, you could borrow up to: ($400K × 85%) – $250K = $90,000. Some lenders may limit to 80% CLTV, which would be: ($400K × 80%) – $250K = $70,000.
Risks of Borrowing Against Your Home
While secured borrowing offers lower rates, it comes with significant risks you should understand:
Foreclosure Risk
If you can’t make payments, the lender can foreclose on your home. Unlike credit card debt, secured debt puts your housing at risk. Default can lead to losing your home.
Most serious risk
Reduced Equity Cushion
Borrowing reduces your equity buffer. If home values drop, you could end up “underwater” (owing more than home is worth), making it hard to sell or refinance.
Market risk
Rate Increases (HELOC)
HELOC variable rates can rise significantly. A 3% rate increase on $50,000 balance adds $1,500/year in interest. Budget for potential payment increases.
Payment risk
Long-Term Debt
You’re trading short-term cash for years of payments. A 15-year home equity loan means 180 monthly payments. Make sure the improvement is worth that commitment.
Commitment risk
When NOT to Borrow Against Your Home
Avoid secured borrowing when: You have unstable income, you’re already stretching your budget, the project is purely cosmetic, you’re planning to sell soon and won’t recoup costs, or you’d be above 80% combined LTV. Consider alternatives like personal loans (no home risk) or saving for non-urgent projects.
Which Option Should You Choose?
| Your Situation | Best Option | Why |
|---|---|---|
| Know exact project cost | Home Equity Loan | Fixed rate, predictable payments, lump sum for contractors |
| Phased project or uncertain costs | HELOC | Draw as needed, pay interest only on what you use |
| Need large amount ($100K+) | Cash-Out Refi | Higher limits, one payment, potentially lower rate |
| Current mortgage rate is high | Cash-Out Refi | Can improve rate while accessing cash |
| Want to keep mortgage separate | Home Equity Loan or HELOC | Second lien doesn’t affect first mortgage |
| Multiple small projects over time | HELOC | Reusable credit line for ongoing needs |
| Risk-averse, want stability | Home Equity Loan | Fixed rate protects against rate increases |
Consider Both
Some homeowners use a combination: a home equity loan for the main project budget (predictable payments) plus a small HELOC for contingencies and unexpected costs. This provides stability with built-in flexibility.
Frequently Asked Questions
What are the ways to borrow against your home?
The three main ways to borrow against your home are: 1) Home Equity Loan – a lump sum with fixed interest rates and predictable monthly payments. 2) HELOC (Home Equity Line of Credit) – a revolving credit line with variable rates where you draw funds as needed. 3) Cash-Out Refinance – replaces your existing mortgage with a larger one, giving you the difference in cash. All three use your home as collateral.
How much equity do I need to borrow against my home?
Most lenders require you to keep 15-20% equity in your home after borrowing (meaning a maximum 80-85% combined loan-to-value or CLTV). For example, if your home is worth $400,000, you’d need to keep $60,000-$80,000 in equity. If you currently owe $250,000 on your mortgage, you could potentially borrow $70,000-$90,000 depending on the lender’s specific CLTV requirements.
Is it a good idea to borrow against your home for improvements?
Borrowing against your home can be smart when: the improvements add value to your home, rates are significantly lower than unsecured alternatives, and the interest is tax-deductible. The risks include: your home serves as collateral (foreclosure possible if you default), you reduce your equity cushion, and you’re committed to payments for years. It’s generally best for necessary repairs and value-adding projects, less ideal for purely cosmetic upgrades.
What credit score do I need to borrow against my home?
Most lenders require a minimum credit score of 620 for home equity loans and HELOCs. For the best interest rates, you’ll want a score of 740 or higher. Some lenders offer programs for borrowers with scores as low as 580, but expect higher interest rates and stricter requirements. Your credit score also affects how much you can borrow and your loan terms.
Can I borrow against my home if I have a mortgage?
Yes—most homeowners who borrow against their home already have a mortgage. The home equity loan or HELOC becomes a “second lien,” meaning it’s in second position behind your primary mortgage. Lenders limit your total borrowing to 80-85% of your home’s value (combined). You’ll have two payments: your original mortgage payment plus the equity loan/HELOC payment. A cash-out refinance combines everything into one new mortgage with one payment.
Is home equity loan interest tax deductible?
Yes, interest on home equity loans and HELOCs is tax-deductible when the funds are used to “buy, build, or substantially improve” the home securing the loan. The deduction limit is interest on up to $750,000 of total qualified mortgage debt ($375,000 if married filing separately). Keep receipts and records showing how funds were used for improvements. Consult a tax professional for your specific situation.
