What is a fixed-rate second mortgage?
A fixed-rate second mortgage is a closed-end loan secured behind your existing first mortgage. You receive a lump sum at closing and repay it over a fixed term at a fixed rate — so your low-rate first mortgage stays untouched. It's the alternative to a cash-out refinance for homeowners who refinanced during the low-rate years.

How Fixed-Rate Second Mortgages Work in Practice
- 1
We measure your equity
We calculate how much equity sits above the combined loan-to-value limit your first lender and the second-lien lender will accept. In most SLO County scenarios that's a large number, because years of appreciation have built substantial equity.
- 2
We size the loan to the purpose
Sometimes the goal is a specific project cost; sometimes it's maximizing available cash. We compare 10, 15, 20, and 30-year terms because the payment difference between them is meaningful.
- 3
We confirm your first mortgage allows it
Almost all institutional first mortgages permit a second lien, but we verify the specific investor guideline and coordinate with your servicer so subordination is handled correctly.
- 4
You close with a fixed payment
Funds arrive at closing. There's no draw period, no variable rate, and no reset — the payment is set for the life of the loan.
San Luis Obispo County scenarios this solves
Fund an ADU without losing a 3% mortgage
The classic SLO County scenario: a homeowner with a low-rate first mortgage needs $150,000 for an ADU. Refinancing would raise the rate on the entire balance, so a fixed second keeps the cheap first debt in place.
Renovation without a cash-out refinance
Kitchen, bath, roof, and solar projects can be funded at a fixed rate with predictable repayment rather than variable HELOC pricing.
Consolidate higher-interest debt
Replacing revolving balances at 20%+ with a fixed-rate second mortgage can meaningfully reduce total interest and monthly outflow — provided the behavior that created the balances changes.
Bridge a down payment
Homeowners with substantial equity can convert a portion into cash for a second home or investment property purchase.

Second mortgage FAQs
Because refinancing replaces your entire first mortgage. If your existing rate is far below today's market, refinancing raises the cost on the whole balance to access a relatively small amount of cash. A second mortgage only prices the new money. It also closes faster and usually costs less.
Yes. Fixed-rate second mortgages are offered by banks, credit unions, and non-bank lenders — availability depends far more on your equity, credit, and income than on geography. Because we work with many lenders, we can usually find an option even when a single bank declines.
Most lenders allow a combined loan-to-value up to 85%, and some go to 90% for strong borrowers. If your home appraises higher than you expect — common in coastal and wine country markets — the available amount can be larger than you assumed. We run the numbers before you commit to a project.
Not always. Many lenders use automated valuation models or a drive-by inspection for smaller loan amounts, which speeds things up and reduces cost. Larger second liens and unusual properties typically require a full appraisal.
Potentially, if the funds are used to buy, build, or substantially improve the home securing the loan, and if you itemize. Using the funds for debt consolidation or another purpose generally changes the treatment. Consult your tax advisor about your specific situation — I'm not providing tax advice.
