If you bought or refinanced your Southern Wisconsin home when rates were low, you may be sitting on real equity and a first mortgage you would rather not disturb. The good news: you can borrow against that equity without giving up the rate on your existing loan. This guide explains how home equity loans and HELOCs work as a separate, second loan, how to decide which one fits your goal, and how to pick a lender if you live in the Madison or Janesville area.
1. How Southern Wisconsin homeowners tap equity without refinancing a low-rate mortgage
Both a HELOC and a fixed home equity loan are second liens. That means they sit behind the first mortgage you already have, as a separate loan, and they leave your first mortgage and its rate alone (Consumer Financial Protection Bureau: second mortgages and junior liens). This is different from a cash-out refinance, which replaces your current first mortgage with a new, larger one at today’s rate (Consumer Financial Protection Bureau: loans similar to a HELOC).
For a homeowner whose first mortgage carries a below-market rate, that distinction is the whole point. A second lien lets you keep the low rate you locked in and borrow against your equity on top of it, instead of trading the whole loan in.
2. HELOC vs. fixed home equity loan: which fits your goal
Both products borrow against the equity in your home, but they behave differently day to day. The right choice usually comes down to how you want to receive the money and how you want to pay it back, not to any single rate number.
A HELOC (home equity line of credit) is a revolving line you can draw from as needed during a set draw period, much like a credit card secured by your home (Consumer Financial Protection Bureau: home equity loans and HELOCs). The rate is typically variable, and you pay interest only on what you actually draw. That makes a HELOC a good fit for staged or open-ended needs, such as a renovation you tackle in phases or a standby reserve you want available but may not use all at once.
A fixed home equity loan gives you the money as a single lump sum, usually at a fixed rate with predictable monthly payments over a set term (Consumer Financial Protection Bureau: home equity loans). Because the payment does not move, this structure is commonly used for debt consolidation or a single large expense, where knowing the exact payoff schedule matters.
A simple way to decide: choose by your goal and your cash flow first, then compare current terms.

3. How to choose a home equity lender in Wisconsin
Once you know which product you want, the lender comparison comes down to a short list of features that genuinely differ from one institution to the next. Use these as your checklist:
•  Second-lien availability. Confirm the lender offers a true second lien (a HELOC or home equity loan that sits behind your existing first mortgage), not only a cash-out refinance.
•  Maximum combined loan-to-value (CLTV). Lenders cap how much of your home’s value you can borrow against. The loan-to-value ratio compares what you are financing with your home’s appraised value (Consumer Financial Protection Bureau: loan-to-value); the combined version, CLTV, counts your first mortgage plus the new loan together. A higher allowed CLTV lets equity-rich homeowners access more of their value.
•  Introductory structure on a HELOC. Some lenders offer an introductory-rate period at the start of the draw. Treat it as a feature to ask about, and read how it adjusts afterward.
•  Local underwriting and servicing. Lenders that underwrite and service the loan in-house, for a defined regional membership, keep the relationship local from application through payoff.
•  Membership eligibility. Credit unions serve a defined field of membership, so confirm you qualify before you apply.
Credit unions, including those serving Southern Wisconsin, underwrite and service home equity loans for their own members rather than selling the relationship on. That is a structural distinction worth weighing alongside the product features above.
4. Heartland Credit Union’s home equity program at a glance
Heartland Credit Union (heartlandcu.org) serves members across southern Wisconsin and offers both a HELOC and a fixed home equity loan as second liens (Heartland Credit Union: home equity loans).
Two concrete features stand out for the equity-rich homeowner who wants to keep a low first-mortgage rate:
•  An introductory-rate HELOC. Heartland’s HELOC includes an introductory-rate special at the start of the line. The current introductory rate, the length of the introductory period, and how the rate adjusts afterward are published, with the required disclosures, on Heartland Credit Union’s home equity loans page.
•  An up-to-100% combined loan-to-value program. For primary residences, Heartland finances up to 100% combined loan-to-value, which matters most for homeowners who want to reach more of their built-up equity. Current terms are published on Heartland Credit Union’s home equity loans page.
Both products are offered to Heartland members. Membership is open to people who live or work in southern Wisconsin (Heartland Credit Union: join).
5. Home equity lenders in Janesville and Rock County
If you live in Janesville or elsewhere in Rock County, it helps to know which lenders keep a physical presence nearby. Heartland Credit Union maintains a Janesville branch inside SSM St. Mary’s Hospital, and Rock County homeowners can apply for either home equity product online or by appointment (Heartland Credit Union: locations).

6. Getting started: applying for a HELOC or home equity loan with a Wisconsin credit union
Applying for a home equity loan with a credit union follows a straightforward path. First, confirm you are eligible to join, since credit unions serve a defined membership. Then the lender reviews your available equity and qualification, much as a first-mortgage lender would. Finally, you close on the new loan as a second lien, leaving your existing first mortgage in place.
To see current introductory-rate and combined-loan-to-value terms, visit Heartland Credit Union’s home equity loans page, where the current figures and required disclosures live. When you are ready, you can apply for a home equity loan online or schedule an appointment at a branch.
If you have built equity in a Southern Wisconsin home and want to put it to work without disturbing the low rate on your first mortgage, a second-lien HELOC or home equity loan is the structure that keeps that rate intact. Decide by your goal first, compare lenders on second-lien availability, combined-loan-to-value, and local servicing, then check current terms before you apply.
