Question 1

How much can I borrow with a HELOC in Los Altos?

Accepted Answer

Most lenders cap total liens — first mortgage plus HELOC — at 80% of your home's value. On a $3M home, that's significant borrowing power.

Question 2

Is a HELOC rate fixed or variable?

Accepted Answer

HELOCs are typically variable, tied to the prime rate. Some lenders offer fixed-rate conversion options after you draw.

Question 3

How long does a HELOC take to close in California?

Accepted Answer

Expect 3–6 weeks for a standard HELOC. High-value Santa Clara County properties may take longer due to appraisal scheduling.

Question 4

Can I use a HELOC to fund an ADU in Los Altos?

Accepted Answer

Yes. Many Los Altos homeowners use HELOCs for ADU builds. The phased draw structure fits construction costs well.

Question 5

What credit score do I need for a HELOC?

Accepted Answer

Most lenders start at 680. Better scores get lower margins above prime — that gap adds up over a 10-year draw period.

Question 6

Should I get a HELOC or a cash-out refinance?

Accepted Answer

Depends on your existing rate. If your first mortgage is low, a HELOC keeps that rate intact. We model both before you decide.
