In short

  • Borrowing: at Minnesota's median home value, a hypothetical line is about $103,680 (math below).
  • State tax: yes. 0.23% of the full line amount, paid once when the mortgage is recorded.
  • Signing: both spouses must sign a mortgage on a married owner's homestead.

How much you could borrow in Minnesota

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 Minnesota'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: $344,600 × 80% − $172,000 owed (about half the value) = $103,680

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.

Minnesota's mortgage registry tax on a HELOC

Minnesota charges a mortgage registry tax of 0.23% of the debt secured by a recorded mortgage (Minn. Stat. § 287.035). For a revolving line of credit, the tax is paid once on the maximum line amount, regardless of how much you draw or repay later (§ 287.05, subd. 3).

Maximum line × 0.23% = Minnesota mortgage registry taxExample: a $100,000 line × 0.23% = $230, even if you never draw it

Hennepin and Ramsey counties can add 0.01% (Minn. Stat. §§ 383B.80, 383A.80). That county authority expires January 1, 2028. Ask your lender whether it pays the tax or adds it to your closing costs, and size your line to what you'll actually use, since the tax is based on the full limit.

Who has to sign

If the owner is married, a mortgage on the homestead isn't valid without both spouses' signatures (Minn. Stat. § 507.02; a mortgage is a "conveyance" under § 507.01). So your spouse signs a HELOC on your homestead even if only you own the home and only you are borrowing. Minnesota is not a community property state.

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 Minnesota?

It depends on your home's value, what you owe and the program's maximum combined loan-to-value. At Minnesota's median owner-occupied value of $344,600 (2024 Census estimate), an 80% CLTV and $172,000 owed, the line would be about $103,680. That's hypothetical math, not a quote.

Is there a mortgage tax on a HELOC in Minnesota?

Yes. Minnesota's mortgage registry tax is 0.23% of the debt, and for a HELOC it's charged on the maximum line amount (Minn. Stat. §§ 287.035, 287.05). A $100,000 line means $230, whether or not you draw it.

Does my spouse have to sign a HELOC in Minnesota?

Yes, if it's your homestead. Minn. Stat. § 507.02 says a conveyance of a married owner's homestead isn't valid without both spouses' signatures, and a mortgage counts as a conveyance.
