Medical Office Acquisition Financing: Multi-Tenant MOB, Southern California

The Situation

A private investor with an existing commercial real estate portfolio identified a 22,000 square foot multi-tenant medical office building in the Inland Empire submarket of Southern California. The property had been owned by the same family for over a decade and was listed off-market through a regional broker relationship. The investor was acquiring the asset at a purchase price of approximately $8.2 million, representing a 7.1% going-in cap rate on in-place net operating income of roughly $580,000 annually.

The tenant roster was a textbook medical office profile. An anchor primary care group occupied 8,500 square feet on a lease with seven years remaining. A physical therapy practice, a radiology group, and a dental group filled the remaining space, each on leases ranging from five to nine years. Combined occupancy sat at 96%. No single tenant represented more than 39% of gross leasable area. The building was purpose-built for medical use with dedicated plumbing, reinforced flooring for imaging equipment, and ADA-compliant exam room configurations throughout.

The investor's objective was a long-duration, fixed-rate loan that would lock in today's debt service and provide maximum cash flow predictability over a 10-to-15-year hold. He had prior experience with bank financing on conventional office and retail assets, but this was his first medical office acquisition. The goal was to execute cleanly within 60 days of opening escrow to preserve the seller's timeline and secure a modest price concession the seller had offered for a fast close.

The Challenge

The investor's initial instinct was to return to his existing bank relationship. The bank offered a 10-year fixed rate at 225 basis points over the 10-year Treasury, with a 25-year amortization schedule and a partial recourse requirement of 25% of the loan balance. At the time of application, that penciled out to approximately 7.35% on a loan the bank was willing to size to 55% of value, or roughly $4.51 million. At 55% LTV, annual debt service would have been approximately $396,000, producing a debt service coverage ratio of 1.46x. Serviceable, but leaving less cash flow than the borrower expected from a stabilized medical asset.

The deeper issue was structural. Banks price conventional office and medical office identically because their internal credit models do not distinguish between tenant categories or space type. Medical tenants statistically renew at rates exceeding 85% compared to 55-65% for general office, and their build-out investment creates a switching cost that general office tenants simply do not face. A radiology group that has installed lead-lined walls and ceiling-mounted imaging equipment is not moving at lease expiration. That embedded tenancy stability is real economic value, but the bank's underwriting model did not capture it, and the bank's rate reflected a generic office risk premium.

Our Approach

CLS CRE positioned this deal for the life insurance company market from the initial consultation. Life companies have been consistent lenders in the medical office sector for precisely the reasons the bank's model ignores: mission-critical tenancy, low vacancy probability, and the predictable, long-duration cash flows that match a life company's liability profile. A 15-year fixed-rate loan on a 96% occupied multi-tenant medical office building is an attractive asset-liability match for a general account portfolio seeking stable yield without equity risk.

We underwrote the deal at 60% LTV. At an $8.2 million purchase price, that produced a loan amount of $4.92 million. The life company we ultimately engaged quoted a 15-year fixed rate of 6.55%, approximately 80 basis points below the bank's 7.35% offer. The loan was structured with 30-year amortization and was fully non-recourse with standard carve-outs. Here is how the debt service math compared:

The life company loan produced a stronger DSCR at a higher loan amount, because the rate differential and the longer amortization period both worked in the borrower's favor. Annual cash-on-cash improved meaningfully. After debt service of $375,000 on NOI of $580,000, the borrower retained $205,000 in annual cash flow before reserves and management. On a cash equity investment of approximately $3.38 million (the down payment plus closing costs), that represented a cash-on-cash return of roughly 6.1% in year one on a non-recourse basis. The bank structure would have yielded approximately $184,000 after debt service on a larger equity check, with personal recourse attached.

The life company's underwriting focused on three variables: debt yield, DSCR, and tenant credit quality. Debt yield, calculated as NOI divided by loan amount, came in at 11.8% ($580,000 divided by $4.92 million), well above the life company's minimum threshold of 9.5% for this property type. DSCR at 1.55x exceeded the 1.30x floor. Tenant quality was reviewed individually. The anchor primary care group operated under a regional health system umbrella. The radiology group held a hospital services contract providing a contractual revenue floor. The underwriter accepted the full rent roll at face value with no credit haircuts, which would not have been the case with a general office tenant mix of similar size and term.

The Outcome

The loan closed in 52 days from term sheet execution. The life company's appraisal came in at $8.35 million, slightly above the purchase price, which confirmed the 60% LTV calculation without adjustment. The borrower closed at the quoted rate with no surprises. Final loan amount: $4.92 million. Fixed rate: 6.55% for 15 years. Amortization: 30 years. Non-recourse. Prepayment structure: yield maintenance for the first 10 years, declining thereafter. The seller received a clean, timely close and the borrower captured the negotiated price concession that had been contingent on speed.

In the 12 months following close, one of the smaller tenants exercised a renewal option at a 6% rent bump, increasing in-place NOI to approximately $597,000. The DSCR improved to 1.59x. The borrower has since used the stabilized asset as a reference transaction when approaching lenders on two subsequent acquisitions, demonstrating the value of a clean life company execution on his first medical office deal.

Key Takeaway

Medical office assets warrant a dedicated lender search, not a reflexive return to your existing bank relationship. The 80-basis-point rate advantage in this transaction was not a negotiating outcome. It was a structural feature of the life company market, which prices medical tenancy as a distinct and superior credit category. On a $4.92 million loan, 80 basis points translates to roughly $21,000 in annual debt service savings, or approximately $315,000 over the 15-year fixed term before accounting for amortization differences. For investors building a medical office portfolio, establishing a direct channel to life company capital, through a broker who has executed these transactions, is one of the highest-return process improvements available before the first term sheet is even requested.
