Lump sum versus revolving credit
A second mortgage gives you a fixed lump sum with a set repayment schedule, similar to a regular mortgage. A HELOC instead gives you access to a credit limit you can draw from as needed, only paying interest on what you actually use at any given time.
Qualifying differences
HELOCs are almost always offered by banks and credit unions with stricter qualifying requirements, including credit score and income verification. Second mortgages, especially through private lenders, tend to have more flexible qualifying based primarily on home equity.
- HELOC: bank product, stricter approval
- Second mortgage: more flexible, often private
- Interest-only options exist on both
Best use cases for each
A HELOC suits ongoing or unpredictable expenses, like a renovation done in phases or a cash cushion for a business. A second mortgage suits a one time need for a specific amount, like paying off debt or funding a down payment.
Interest rate structure
HELOC rates are usually variable and tied to prime rate, meaning payments can shift over time. Second mortgages often carry a fixed rate for the term, giving more predictability in monthly payments even though the starting rate may be higher.
Frequently asked questions
- Can I get a HELOC if I already have bad credit?
- It is difficult through banks, since HELOCs typically require good credit, making a private second mortgage a more realistic option in that situation.
- Do I have to use the full amount of a second mortgage right away?
- Yes, second mortgages are typically disbursed as a lump sum at closing, unlike a HELOC where you draw funds as needed.
- Which option is better for an ongoing renovation project?
- A HELOC is often better suited since you only pay interest on funds drawn as each phase of the project is completed.
