$1,162,000 Private Money Loan for a 10-Unit Multifamily Acquisition in Castro Valley, California
Rubicon Mortgage Fund, LLC provided a $1,162,000 private money loan to acquire a 10-unit multifamily property in Castro Valley, California. The seller was working under a tight closing window, and the buyer needed to fund quickly. The financing was structured as an asset-based loan and closed in under a month, giving the borrower time to complete improvements, raise the property’s below-market rents, and transition to long-term financing once the building is stabilized.
The deal
A seasoned real estate investor set out to acquire a 10-unit apartment building in Castro Valley, California. The property is roughly 12,548 square feet on a 13,068 square foot lot, made up of nine two-bedroom, one-bathroom units and one one-bedroom, one-bathroom unit.
The building was nearly fully occupied, with a single vacant unit at the time of purchase. Most of the units were renting well below market, and the interiors had not seen meaningful improvements in some time. That combination is exactly what made the property attractive to the buyer, who planned to renovate, bring rents up to market, and reposition the asset for a bank refinance down the road.
Why the timeline mattered
The opportunity came to Rubicon through a banking referral. The seller was completing a 1031 exchange and was working against a short close-of-escrow window, which meant the buyer had to be ready to fund fast.
Conventional financing was on the table early, but because the in-place rents were below market, the property’s current income did not support the debt coverage a bank loan requires. With the property not yet stabilized, that path could not come together inside the seller’s timeline. Rubicon was brought in to meet the close, with the referring banker positioned to provide long-term financing once the improvements are complete and the rents reflect market value.
The Rubicon solution
Rubicon Mortgage Fund, LLC underwrote the private money loan on the strength of the asset and the borrower’s plan rather than the property’s current income. That approach is what allows private financing to move at the speed a deal like this requires.
The $1,162,000 private money loan closed in under a month, well inside the seller’s exchange window. The borrower now has room to execute the rehab-and-lease strategy: complete the interior work, lease the vacant unit, raise the below-market rents, and stabilize the building’s cash flow. Once the property is performing, the borrower can move into permanent bank financing.
For this borrower, a repeat multifamily investor with other properties across the Bay Area, the value was straightforward. The financing removed the timing risk, protected the acquisition, and created a clear runway to add value.
Why this private money loan fit Rubicon
Castro Valley is a working-class East Bay community and one of the area’s more attainable multifamily markets, drawing residents who want proximity to San Francisco and Oakland at a lower cost. That steady rental demand supports value-add strategies like this one.
Deals like this are a natural fit for Rubicon Mortgage Fund. The property was sound, the location was strong, and the borrower had a clear plan and a track record to back it up. When a purchase depends on closing quickly and the numbers need time to catch up, asset-based private financing can bridge that gap.
FAQ
What is a private money loan for a multifamily acquisition? It is short-term financing used to purchase an apartment or multi-unit property, secured by the asset itself. Lenders like Rubicon Mortgage Fund, LLC focus on the property and the borrower’s business plan rather than only the building’s current income, which makes this type of loan well suited to value-add purchases.
Why would a buyer use private financing instead of a bank for an apartment building? When a property’s in-place rents are below market, its current income may not meet the debt coverage a bank requires. Private financing lets a qualified borrower close on the acquisition, complete improvements, raise rents, and then transition to long-term bank financing once the property is stabilized.
How fast can Rubicon close a multifamily acquisition loan? Timelines depend on the deal, but Rubicon regularly closes when speed matters. In this Castro Valley transaction, the private money loan closed in under a month to meet the seller’s 1031 exchange window.
What is a rehab-and-lease strategy? It is a plan to buy an underperforming property, renovate the units, lease vacant space, and bring rents to market. The goal is to increase the property’s income and value so it can qualify for permanent financing or a sale.
