Does a HELOC require an appraisal?

Not always. Many lines are approved with an automated value.

Valuation types

If the value comes in low

Ask whether the lender will accept a full appraisal instead of an automated value, send recent comparable sales and a list of improvements with dates and costs, or take a smaller line.

Who pays for valuation

Automated values are usually free to you. Full appraisals are often paid by the borrower, or covered by the lender on "no closing cost" lines in exchange for an early-closure fee. Ask before ordering.

Preparing for an appraiser

• List improvements since you bought, with dates and approximate costs.
• Have permits for additions or finished basements available.
• Make every room accessible, including attic and crawlspace.

How automated valuations work

An automated valuation model estimates value from public records and recent nearby sales. It's fast and free to you, but it relies on data: homes in neighborhoods with few sales, very large or custom homes, and recently remodeled homes are often undervalued or can't be valued at all. If you've just finished a major remodel, tell the lender; a full appraisal may give you a larger line.

The valuation types

When the value comes in low

1. Ask for the report and check the facts: square footage, bedrooms, lot size, and whether recent upgrades were noted.
2. Gather better comparable sales: similar homes, sold recently, nearby. Send them to the lender with a request for reconsideration of value.
3. Ask whether another lender uses a different valuation method. AVMs from different providers can disagree by tens of thousands of dollars.
4. Take a smaller line now and request an increase later if values rise.

Getting the home ready

• Make a one-page list of improvements with dates and costs: roof, HVAC, kitchen, windows.
• Make sure every room is accessible, including the attic and crawl space.
• Fix small visible issues: dripping faucets, missing smoke detectors, broken windows.

Example

A homeowner expects $850,000; the automated valuation says $790,000, limiting her line. She asks for a full appraisal, provides her remodel list and three recent sales, and the appraisal comes in at $835,000, raising her available line by about $38,000 at an 85% cap.

Also asked

Can I use a recent appraisal I already have for a HELOC?

Some lenders accept an appraisal from the past few months if it was done for a lender; others order their own.

Can I be present for a HELOC appraisal?

Yes, you can be there when the appraiser visits. Point out upgrades and share a list of improvements with dates and approximate costs, but let the appraiser work.

What if the automated HELOC valuation comes in too high?

A HELOC lender may still lend on an automated valuation that comes in higher than you expect. Don't overborrow based on an optimistic estimate just because the larger line is available.

Does a HELOC appraisal look at the inside of my home?

Only a full HELOC appraisal includes an interior inspection. Automated valuations and desktop appraisals involve no visit, and drive-by appraisals view the exterior only.

Is an appraisal for a HELOC the same as for a purchase?

The methods are the same, but a lender may order a less detailed type for a HELOC, such as a desktop or exterior-only appraisal, especially for smaller lines. Purchase appraisals are almost always full interior inspections.
