Missouri HELOC Rates and Rules 2026: Spouse Signatures

HELOC rates in Missouri right now

Most HELOCs have a variable rate based on the prime rate plus a margin set by the lender. Your margin depends mostly on your credit and how much of your home's value you borrow.

In 2025, the median HELOC in Missouri opened at 7.50%, and half opened between 5.99% and 8.29%, across 13,980 lines reported under federal HMDA data. The national median was 7.50%. Leaving out lines with a 3 to 12 month introductory rate, the Missouri median was 8.00%. Home equity loans in Missouri, which usually have a fixed rate, closed at a median of 8.75%. HELOC rates in every state.

Prime rate, unchanged since September 17, 2026 (Federal Reserve): 7.00%
Median Missouri HELOC rate at opening, 2025 (HMDA): 7.50%
Average 30-year fixed mortgage rate, week of October 29, 2026 (Freddie Mac): 7.24%

The Federal Reserve raised rates on September 16, 2026, which moved prime to 7.00%. Its October 27 and 28 meeting is more recent than the prime rate data shown here, which runs through October 27, 2026. Its next meeting is December 8 and 9. With 30-year mortgage rates above 7%, a HELOC lets you borrow against your equity without refinancing a lower rate you already have.

How much can you borrow in Missouri?

Missouri law doesn't set a home equity borrowing cap. Each lender sets its own limit on all the loans on your home combined, your current mortgage plus the new line.

With 41.2% of Missouri owners holding no mortgage at all, a bit above the 40.3% U.S. share, many have most of their home value available to borrow against.

Home value ×80% −what you owe now =a likely maximum line

Example

Home value (the Missouri median for owner-occupied homes): $254,400
80% of value (a common lender limit, not a Missouri law): $203,520
Current mortgage balance: $130,000
Maximum line of credit: $73,520

Example only. Lenders set their own limits and the final amount after an appraisal, and many approve less than the maximum based on credit and income.

The Missouri rules that affect a HELOC, in plain English

Missouri has no HELOC borrowing cap, waiting period or state right to cancel. It does have rules on who signs, how a credit-line deed of trust works, what a lender can charge on second mortgages made under its Second Mortgage Loan Act, and how foreclosure works. Here they are in plain words.

Who signs

Both spouses sign.: Missouri law voids a mortgage on the family homestead made by one spouse alone. If you are married and borrowing against the home you live in, plan on both of you signing.
A small homestead exemption.: Missouri protects $15,000 of your home's value from most creditors, rising to $40,000 on January 1, 2027. It doesn't block a mortgage both spouses signed.

Your line of credit

One recording covers every draw.: When your deed of trust says it is governed by Missouri's future-advance law, it secures later draws up to the stated limit from the day it was recorded, even if your balance sits at zero for a while.
You can stop new draws.: The owner can send the lender a notice, by certified mail or personal delivery, ending the deed of trust as security for future draws. Within 15 days the lender must record a statement of the balance owed, and draws made after it got the notice are not secured by your home.

Fee limits on Missouri second mortgages

Origination fee up to 5%.: If your line is made under Missouri's Second Mortgage Loan Act, the lender's origination fee can't exceed 5% of the principal. Other charges are limited to a set list, such as recording fees, taxes, and title, appraisal and credit report fees paid to third parties.
An annual fee of $50 at most.: On a revolving line made under that law, the yearly fee is capped at $50.
Late charges only after 15 days.: A late charge can apply only to a payment not made within 15 days of its due date. It is 5% of the payment or $15, whichever is greater, never more than $50, and only once per payment.
Pay it off any time.: You have an unconditional right to prepay a second mortgage loan made under that law.

Licensing and property tax

Use a licensed lender.: Mortgage brokers and lenders need a license from the Missouri Division of Finance. Banks and credit unions are exempt, and loan officers need a license or registration through the national NMLS system.
Taxed on 19% of value.: Missouri assesses homes at 19% of their true value. Assessors set new values every odd-numbered year, and those values carry into the following year.

If you can't pay

20 days' notice before a sale.: A Missouri deed of trust can be foreclosed by a trustee sale instead of a lawsuit, at the lender's option. You must be sent notice by certified or registered mail at least 20 days before the sale, and the sale must be advertised in a local newspaper.
A narrow one-year buyback right.: If the lender itself buys your home at the sale, you can redeem it within one year. You must give written notice at the sale or in the 10 days before it, post a bond within 20 days after it, and then pay the debt, interest and costs.

Frequently asked questions

Does my spouse have to sign my HELOC in Missouri?

If the line is secured by your family homestead, yes. Missouri law voids a mortgage on the homestead made by one spouse alone, so both spouses sign.

Can I stop new draws on my Missouri HELOC?

Yes, if your deed of trust is governed by Missouri's future-advance law. Send the lender a notice by certified mail or personal delivery; within 15 days it must record the balance owed, and later draws aren't secured by your home.

What fees can a Missouri second mortgage lender charge?

Under Missouri's Second Mortgage Loan Act: an origination fee of up to 5%, listed third-party closing costs, an annual fee of no more than $50 on a revolving line, and a late charge only after 15 days. You can prepay at any time.

How does foreclosure work in Missouri?

A deed of trust can be foreclosed by a trustee sale without a lawsuit. You must be mailed notice at least 20 days before the sale, and the sale is advertised in a local newspaper.

Can I get my home back after a Missouri foreclosure sale?

Only in a narrow case. If the lender bought the home at the sale, you can redeem it within one year by giving notice at or shortly before the sale, posting a bond within 20 days, and paying the debt and costs.

On the FHFA House Price Index, Missouri prices rose 38.2% over 5 years and 110.6% from 2014 to 2025. In the year to mid-2026 they rose 3.76%, 15th of the 50 states and DC.
