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 California the second is a deed of trust, and a deal anywhere in San Luis Obispo County records with the one County Clerk-Recorder. Short-term rental rules here run in opposite directions from the city to the unincorporated county, so where the rental sits shapes how its income gets read. 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
Is a second mortgage on a San Luis Obispo rental regulated in California if it is business purpose?
Yes. California regulates business-purpose real estate lending; the question is under which law. The California Financing Law covers commercial loans of $5,000 or more whose proceeds are for something other than personal, family or household use, and the state regulator says that includes loans secured by residential real estate. The two lawful routes are a CFL license or a real estate broker license. The residential mortgage lending act defines its scope by a federal term that reaches first or subordinate liens on 1 to 4 unit residential property; federal rules separately exempt credit made primarily for a business purpose, and no state guidance we found says whether that exemption carries into the state definition. That is why we ask what the funds are for and whether you live in the property. The homestead exemption and the Homeowner Bill of Rights are built around a residence you occupy, so neither is the framework for a business-purpose second on a rental. This is not legal advice; talk to your attorney about your own structure. See the second mortgage program page for terms.
What happens to a second lien on a San Luis Obispo rental if the first is foreclosed?
A senior trustee sale can wipe out the second, so the second's protections come before the sale and from the surplus. California deeds of trust are foreclosed by trustee sale, at auction, in the county where the property sits, between 9 a.m. and 5 p.m. on a business day. The holder of a later-recorded deed of trust must be mailed notice within one month after the senior's notice of default records, and notice of sale at least 20 days before the sale (Civil Code section 2924b). A junior can reinstate the senior loan up to five business days before the sale date in the first recorded notice of sale (section 2924c), and surplus sale proceeds pay junior liens in order of priority before the owner sees any (section 2924k). For a 1 to 4 unit property, eligible bidders such as tenant buyers and prospective owner-occupants get a post-sale window under section 2924m, so the result is not final at the gavel. The trustee-sale anti-deficiency rule, Code of Civil Procedure section 580d, was described by the California Supreme Court in Black Sky Capital v. Cobb (2019) as not appearing to extend to a junior whose security was sold out in a senior sale. How that plays out on a particular loan is fact-specific; ask counsel. Where a given sale happens is stated in that property's recorded notice of sale. Read lien position explained for how position works.
What is Civil Code 2924.13, and does it reach a second on a rental?
It is a 2025 gate on foreclosing any junior lien on residential property, and whether it reaches business-purpose seconds is being litigated. The section, added by AB 130 and signed on June 30, 2025, defines a "subordinate mortgage" as a security instrument in residential real property, including a deed of trust, that was junior to another security interest when recorded. It makes foreclosure unlawful where the servicer gave the borrower no written communication for at least three years or failed to provide a periodic account statement the law required, and a nonjudicial foreclosure cannot proceed until the servicer records a certification under penalty of perjury and mails it to the borrower. No unit-count, occupancy or loan-purpose limit appears in the text. California Mortgage Association v. Bonta, filed in federal court in September 2025, alleges the section reaches both consumer and business loans; that is an allegation, not a ruling, and no outcome was found. If you plan to refinance your first later, the second-lien holder generally has to sign a resubordination agreement as well. This is not legal advice; your attorney or title company has the final say.
What does San Luis Obispo County charge to record a deed of trust?
The base fee is $14 for the first page and title and $3 for each added page, before state add-ons. The County Clerk-Recorder adds $14 for each additional title. Its fee calculator also lists the SB 2 Building Homes and Jobs Act fee of $75 per real estate instrument, per transaction, per parcel; under the statute it is capped at $225 and exempts a transfer subject to documentary transfer tax and a transfer to an owner-occupier, and a cash-out second recorded without a sale fits neither exemption on its face. The calculator also shows a $2 Restrictive Covenant Program fee per instrument and a $7 Real Estate Fraud Prosecution fee on listed documents, so ask whether your deed of trust is on that list. California charges no documentary transfer tax or mortgage tax on a deed of trust (Revenue and Taxation Code section 11921). The county's recording page names two routes for documents, by mail or in person at the Clerk-Recorder office, and one recorder covers every city and the unincorporated county. These are county charges as published on the county's page, not a quote for your documents; get the total from the recorder or your title company.
Can a San Luis Obispo rental earn short-term rental income?
It depends on which side of the city limit it sits. In the City of San Luis Obispo, a whole-home short-term rental is a prohibited use; only homestays are allowed, and the operator verifies the home as a primary residence every year, which appears to rule out short-term income on a rental you do not live in. Confirm with the city before you count on it. Pismo Beach stopped issuing new short-term rental licenses on November 7, 2023, and its permits do not transfer on a sale. Morro Bay caps full-home permits in residential zones at 175, and Paso Robles caps non-hosted rentals at 325 citywide with a 75-permit sub-cap in the R-1 zone. The unincorporated county runs the opposite way: vacation rentals are legal with a Zoning Clearance and a Business License, and the county reports more than 2,200 registered license holders. Our program lends on short-term rentals; the local rules decide whether a given property can operate as one. Separately, California lets a homeowners association ban rentals of 30 days or less (Civil Code section 4741).
Does the City of San Luis Obispo require rental registration or inspections?
We found no rental registration program and no rental inspection cycle in the city. Enforcement is complaint-driven, through the Safe Housing Program run by Code Enforcement. Use the second mortgage calculator to see what the equity supports.
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.
