Orange County rental equity through a second mortgage, first untouched.
Our second mortgage program covers non-owner-occupied 1 to 4 unit residential investment property, including short-term rentals, worth at least $100,000. It is a separate fixed-rate loan, as a lump sum or a line of credit, behind your first mortgage, which stays in place. In Orange County the city matters as much as the county: short-term rental rules are set city by city, while every deed of trust records with the one county Clerk-Recorder. Business-purpose only, and every loan is conditional on the borrower and the property, subject to underwriting.
Typical figures, subject to underwriting and market conditions. Not a commitment to lend.
How it works
We lend against the equity in a rental you already own, as a lump-sum second or a line of credit, so your first mortgage and its rate stay in place. Combined loan-to-value, counting every lien, goes up to 80%, subject to underwriting. Check that your first mortgage allows a junior lien.
Who it's for
Rental owners who want to keep their first mortgage
Investors funding a down payment or renovation
Non-owner-occupied investment property only, including short-term rentals
Do California's homeowner protections cover a second mortgage on my Orange County rental?
Mostly not, because they are built around your own home. California's homestead exemption protects the debtor's principal dwelling from judgment creditors, and by statute the exemptions do not apply to the foreclosure of a deed of trust at all. The Homeowner Bill of Rights is limited to owner-occupied first liens securing a loan made for personal, family or household purposes, so a business-purpose second on a rental sits outside it on both counts. One rule does reach rentals: CCP 580e bars a deficiency after a lender-approved short sale of a dwelling of up to four units with no occupancy test, but it does not apply when the borrower is a corporation, LLC or limited partnership, so how you hold title matters. Business-purpose real estate lending is itself a licensed activity in California, under the California Financing Law or a real estate broker license. This is not legal advice; your attorney or title company has the final say. See the second mortgage program page for terms.
What happens to a second on my Orange County rental if the first mortgage is foreclosed?
The second lender gets notice, a chance to cure, and a place in line for any surplus. California deeds of trust are usually foreclosed by trustee sale under the power of sale, with at least three months between the notice of default and the notice of sale. Civil Code 2924b requires notice of the default to be mailed, within one month of recording it, to the holder of any later-recorded deed of trust, and notice of the sale at least 20 days before it. Under 2924c a junior lienholder can reinstate the senior loan until five business days before the sale date in the first notice of sale. If the sale brings more than the senior debt and costs, 2924k pays junior liens in order of priority before anything goes to the owner. Under 2924m a trustee sale of a 1 to 4 unit property is not final at the gavel, because eligible bidders such as tenants and prospective owner-occupants get a window after the sale, so surplus can take longer to settle. The sale must be held in the county, between 9 a.m. and 5 p.m. on a business day, and the recorded notice of sale names the place for each property. Read lien position explained before you stack debt.
If a foreclosure of the first wipes out the second on my Orange County rental, is that debt gone?
That depends on facts a court would weigh, not on one rule. For an Orange County rental carrying two loans, the starting point is the statute and two state Supreme Court cases. CCP 580d bars a deficiency on a note whose own deed of trust was sold under a power of sale. In Black Sky Capital v. Cobb (2019), the California Supreme Court restated Roseleaf v. Chierighino (1963): section 580d "does not appear to extend to a junior lienor whose security has been sold out in a senior sale." On the facts in Black Sky, where one creditor held both notes, signed more than two years apart with no evasive loan splitting, the court held that 580d did not bar a deficiency on the junior note. Those are holdings on their facts, not a rule for any other loan. Separately, Civil Code 2924.13, signed on June 30, 2025 as part of AB 130, makes it unlawful to foreclose a subordinate deed of trust on residential property if the servicer sent the borrower no written communication for at least three years or skipped a periodic statement the law required, and bars a nonjudicial foreclosure until the servicer records and mails a certification under penalty of perjury. The statute's text shows no unit-count, occupancy or loan-purpose limit, and whether it reaches business-purpose seconds is unsettled: a lawsuit filed September 8, 2025 (California Mortgage Association v. Bonta, E.D. Cal.) alleges it reaches both consumer and business loans, which is an allegation, not a ruling. How either rule applies to your loan is a question for your attorney.
What does it cost to record a second deed of trust in Orange County?
Recording fees, yes; transfer tax, no. California's documentary transfer tax does not apply to an instrument given to secure a debt, and the state charges no mortgage tax, so the transfer tax line on the county schedule is for conveyances, not your deed of trust. The Orange County Clerk-Recorder's schedule effective September 1, 2026 lists $12 for the first standard page, $3 for each additional page and a $75 SB 2 fee per title unless an exemption applies. The SB 2 exemptions cover a recording tied to a transfer subject to transfer tax or a transfer of a home to an owner-occupier, and a cash-out second recorded without a sale fits neither on its face. As an illustration, not a quote for your documents: a 20-page deed of trust comes to $12 + (19 x $3) + $75 = $144 on those lines, before any other charge on the schedule. One recorder serves all 34 cities and the unincorporated areas, and it accepts electronic recording from approved submitters; the office says 80% of its documents now arrive electronically.
Do Orange County short-term rental rules affect a second on my rental?
Yes, and the answer depends on the city, not the county. The program accepts short-term rentals, but Orange County has 34 sets of rules. Short-term rentals are banned in Irvine, Costa Mesa, Garden Grove, Tustin, Westminster, Lake Forest, Laguna Niguel, Aliso Viejo, Villa Park and Yorba Linda, and allowed with a permit in Huntington Beach, Newport Beach, Fullerton, Orange, Placentia and Buena Park. Irvine treats a stay under 31 consecutive days as a short-term rental and prohibits it in every residential zone, and advertising one is also a violation. Anaheim's codified chapter covers only rentals permitted before its 2015 moratorium; the permit is personal to the owner and does not run with the land. So short-term rental income is not underwritten on a new purchase in Irvine or Anaheim. Check the HOA too: California voids most association bans on renting, but lets an association prohibit rentals of 30 days or less.
What on an Orange County tax bill should I check before borrowing against a rental?
The direct charges, which the tax rate does not show. The county's tax rate book gives only the ad valorem rate. Mello-Roos special taxes, 1915 Act assessments and PACE assessments are fixed-dollar charges on the same bill, and in tax year 2025 they totalled $315,378,143 across 120,290 parcel-district records countywide, per the Auditor-Controller's report as of May 8, 2026. PACE assessments, a clean-energy financing charge, show up there as their own lines. Read the fixed-charge section of your current bill line by line before you size a second, because those charges come out of the same rent that has to carry both loans. Our CLTV guide walks through the math.
Local rules move. Every tax rate, fee, ordinance and market figure here comes from a primary source and carries the date we read it, and we correct them as the rules change. Where a number is mid-change or we could not verify it, we say so rather than guess. Before you commit a budget, confirm anything that drives it with the city or county, and talk to your attorney or CPA on questions of law or tax.
