In short

  • Borrowing: at Idaho's median home value, a hypothetical line is about $134,120 (math below).
  • State tax: none found on recording a HELOC. The recorder's fee is $45.
  • Signing: community property state. Both spouses sign to encumber community real estate.

How much you could borrow in Idaho

A HELOC limit starts with your home's value, the share of it a program will lend against in total, and what you already owe. Here's the math using Idaho's median owner-occupied home value from the U.S. Census Bureau's American Community Survey (2024).

Home value × maximum CLTV − mortgage balance = largest possible lineHypothetical: $446,400 × 80% − $223,000 owed (about half the value) = $134,120

Hypothetical math, not a quote. The 80% combined loan-to-value (CLTV) is an assumption; the maximum depends on the program, your credit and the property, and income and debts can lower the line further. Run your own numbers in the HELOC calculator.

Idaho recording costs on a HELOC

We found no Idaho tax on recording a mortgage: no mortgage registry, recordation, intangible or stamp tax in the Idaho Code. The state-set charge is the county recorder's fee, $45 to record a deed of trust or mortgage of up to 30 pages (Idaho Code § 31-3205). Lender fees and other third-party costs are separate.

Who has to sign

Idaho is a community property state: property acquired during marriage is generally community property (Idaho Code § 32-906). Neither spouse can encumber community real estate unless the other joins in signing (§ 32-912), so if your home is community property, your spouse signs the HELOC even if only you are borrowing. If the home is one spouse's separate property, ask the lender and title company who needs to sign.

Federal rules that apply in every state

  • You get a three-business-day right to cancel a HELOC on your principal home. See where to find your terms.
  • A variable-rate HELOC can change only with a public index outside the lender's control, and it must have a lifetime rate cap. See how HELOC rates are set.
  • Your lender must give you HELOC disclosures and the CFPB's HELOC booklet when you apply.

Frequently asked questions

How much can I borrow with a HELOC in Idaho?

It depends on your home's value, what you owe and the program's maximum combined loan-to-value. At Idaho's median owner-occupied value of $446,400 (2024 Census estimate), an 80% CLTV and $223,000 owed, the line would be about $134,120. That's hypothetical math, not a quote.

Is there a mortgage tax on a HELOC in Idaho?

We found none in the Idaho Code. The county recorder charges a $45 fee to record a deed of trust or mortgage (Idaho Code § 31-3205). Lender and other third-party fees are separate.
