How much can I borrow with a HELOC?

Most lenders allow you to borrow up to 80-85% of your home's value minus your remaining mortgage balance. For example, if your home is worth $400,000 and you owe $250,000, your available equity is $70,000-$90,000 (80-85% of $400K = $320K-$340K minus $250K owed). Some lenders go up to 90% LTV.

What is the difference between a HELOC and a home equity loan?

A HELOC is a revolving credit line (like a credit card) with variable rates — you draw funds as needed during a 5-10 year draw period. A home equity loan is a lump sum with a fixed rate and fixed monthly payments. Choose a HELOC for ongoing or variable expenses, and a home equity loan when you need a specific amount with predictable payments.

Can you lose your house with a HELOC?

Yes. A HELOC uses your home as collateral. If you can't make payments, the lender can foreclose. This is the most important risk to understand — you're converting unsecured spending into secured debt backed by your home. Only borrow what you can confidently repay.

Before You Get a HELOC: 8 Things to Know

Before you get a HELOC, understand that your home is the collateral. If you can’t make the payments, you could lose your house. The low rates are attractive, but the risks are real — especially with variable rates during the repayment period.

8-Point HELOC Checklist

#	Check This	Why It Matters
1	Calculate your available equity	Home value × 80-85% minus mortgage balance
2	Understand draw vs. repayment periods	Interest-only during draw; P&I during repayment
3	Check the variable rate terms	How high can the rate go? What index is it tied to?
4	Compare HELOC vs. home equity loan vs. other options	Fixed rate may be better for large one-time expenses
5	Determine what you’re using it for	High-value purposes only — not vacations or shopping
6	Budget for the repayment period payment shock	Monthly payments can double or triple when draw period ends
7	Check for fees and penalties	Annual fees, early closure fees, inactivity fees
8	Make sure you can repay even if home values drop	Owing more than your home is worth = underwater

HELOC vs. Home Equity Loan

Feature	HELOC	Home Equity Loan
How funds are disbursed	Revolving credit line — draw as needed	Lump sum
Interest rate	Variable (tied to prime rate)	Fixed
Monthly payment	Variable (interest-only during draw)	Fixed
Draw period	5-10 years	N/A — receive full amount upfront
Repayment period	10-20 years (P&I)	5-30 years (P&I)
Best for	Ongoing expenses, renovations, emergency fund backup	One-time expense, debt consolidation, specific project
Risk level	Higher (variable rate + payment shock)	Lower (predictable payments)

Equity Calculation

Your Home	Example
Current home value	$400,000
Maximum LTV allowed (80%)	$320,000
Current mortgage balance	-$250,000
Available HELOC amount	$70,000

LTV Limit	Available HELOC ($400K home, $250K owed)
80%	$70,000
85%	$90,000
90%	$110,000

Payment Shock Example

Period	Balance	Rate	Monthly Payment
Draw period (years 1-10)	$60,000	8.5%	$425 (interest only)
Repayment period (years 11-20)	$60,000	9.5%	$634 (P&I)
Repayment if rates rise	$60,000	12%	$860 (P&I)

Payments can increase 50-100% when the draw period ends and principal repayment begins.

Good and Bad Uses for a HELOC

Good Uses	Bad Uses
Home improvements that add value	Vacations or lifestyle spending
Debt consolidation (if disciplined)	Investing in speculative assets
Emergency fund backup (not primary)	Funding a business with uncertain income
Education expenses (compare vs. student loans)	Buying a car (use an auto loan instead)
Bridge financing between home sale and purchase	Daily expenses or recurring bills

HELOC Fees and Costs

Fee	Typical Amount	Notes
Application fee	$0-$500	Some lenders waive this
Appraisal	$300-$600	Required to confirm home value
Annual fee	$0-$100	Charged whether you use the line or not
Early closure fee	$300-$500	If you close within 2-3 years
Inactivity fee	$0-$100/year	Some lenders charge if you don’t use it
Transaction fee	Usually $0	Unlike credit cards, most HELOCs have no per-draw fee

Risks to Understand

Risk	What Could Happen
Variable rate increases	Prime rate rises → your payments rise with no cap in many cases
Payment shock at repayment period	Going from interest-only to P&I dramatically increases payments
Home value drops	You could owe more than your home is worth (underwater)
Lender freezes the line	Banks can freeze or reduce your HELOC if home values fall
Foreclosure	Miss payments and the lender can take your home
Tax deduction limits	Interest is only deductible if funds are used for home improvement

The Bottom Line

A HELOC offers low-rate access to your home equity, but it’s secured by your house. Before you open one, make sure the purpose justifies the risk (home improvements and debt consolidation = reasonable; vacations and discretionary spending = dangerous). Budget for the repayment period payment increase, and don’t borrow the maximum just because it’s available. If you need a predictable payment, a fixed-rate home equity loan is the safer choice.

Your available equity determines how much you can borrow — lenders typically require 15–20% equity remaining after the HELOC draws. If your credit score doesn’t meet standard HELOC requirements, see home equity loan with bad credit for lenders that work with lower scores. The loan-to-value ratio (LTV) is the key metric lenders use — understanding it helps you calculate how much equity you can access before applying.
