Rubicon Mortgage Fund, LLC provides private money 1031 exchange loans for commercial real estate investors across California.
A 1031 exchange allows investors to defer capital gains taxes by reinvesting the proceeds from a property sale into a like-kind replacement property under Section 1031 of the Internal Revenue Code. The IRS imposes strict timelines: 45 days to identify the replacement property and 180 days to close. Missing either deadline disqualifies the exchange and triggers the deferred tax liability.
When timing is tight, private money bridge financing is often the solution that keeps the exchange intact. Rubicon Mortgage Fund, LLC has been providing 1031 exchange loans for commercial real estate investors throughout California since 2008, based in Lafayette in the San Francisco Bay Area.
Rubicon evaluates the replacement property on its own merits: location, current market value, physical condition, and the borrower's equity position relative to the exchange proceeds. We conduct a physical inspection of every property we lend on. No personal credit check, tax returns, or income verification is required. We work directly with the borrower's qualified intermediary to ensure the loan structure complies with IRS exchange requirements.
We lend to individuals, LLCs, corporations, trusts, and partnerships. We are experienced with both forward and reverse 1031 exchange structures.
If your 1031 exchange deadline is approaching, contact Rubicon Mortgage Fund, LLC as early as possible in the process. We serve investors throughout California including the San Francisco Bay Area, Northern California, Sacramento, Los Angeles, and San Diego. We typically provide an initial response and preliminary terms within 24 hours of inquiry and coordinate directly with your qualified intermediary.
Rubicon Mortgage Fund writes 1031 exchange loans on California commercial property, funding replacement purchases against deadlines the IRS does not move.

Most failed exchanges do not fail because the investor ran out of time to look. They fail because financing did not arrive on a date that could not move.
Identification is binding. Close on something not on the list and the exchange is dead. So the identified properties need to be ones a lender will actually fund — which means knowing your financing before day 45, not after.
Investors who identify three properties and only investigate financing on their first choice are the ones who call us on day 120.
The clock does not pause for a lender’s credit committee, a slow appraisal, an environmental report, or a seller who takes three weeks to sign an amendment. A conventional process that normally takes 90 days has no margin left inside 180 when the first 45 went to identification.
Investors trading out of a simple asset frequently trade into something a bank finds harder: a property in transition, an unusual property type, or a partially vacant building bought for its upside. That is precisely where conventional financing slows down and asset-based lending does not.
In a reverse exchange the replacement property is acquired before the relinquished property sells, with an exchange accommodation titleholder parking title in between. It solves a real problem — you found the right property before yours sold — and it needs financing that can work with a parked-title structure and a short horizon.
Rubicon has funded reverse exchange transactions including a $9,025,000 reverse 1031 exchange. Conventional lenders are frequently unwilling to lend into an accommodator structure at all.
Full parameters are on our borrowers and lending criteria page. Closed transactions are listed under funded loans, and purchase financing generally is covered on our acquisition loans page.
Most borrowers have preliminary terms within 24 hours and closings inside 30 days are routine. We have moved faster when an exchange deadline required it.
Yes. We have funded reverse exchanges, including transactions using an exchange accommodation titleholder.
Call today. Thirty days is workable for us, but every day spent deciding is a day removed from a deadline that does not extend.
No, on any loan. Someone from Rubicon inspects the property in person, which is a large part of how we hold a closing date.
Yes. We underwrite the asset and the plan rather than trailing income.
Yes. We lend to individuals, LLCs, corporations, trusts and partnerships, including recently formed entities.
No. We are a lender, not a tax adviser or a qualified intermediary. Take the structure, the identification and the debt replacement question to your CPA and your intermediary — we will work alongside them.
