Office Building Financing for CRE and Medical Office Assets

Office CRE financing still exists, but educationally it is useful to separate traditional office from medical office (MOB) conversations. Traditional office may face higher vacancy and renewal uncertainty in some metro markets. Medical office often ties to healthcare providers, outpatient demand, and different tenant credit stories—though MOB is not immune to lease rollover or CapEx needs.

Sponsors pursue office loans for purchase, refinance, and selective value-add when the business plan is explicit about leasing, TI budgets, and hold period. Trophy CBD towers and small suburban garden offices are not underwritten the same way; class, submarket, and parking ratios matter.

If your asset blends office with apartments or retail, see mixed-use property financing. Pure retail strip belongs on retail property financing. For transitional vacancy, compare bridge loans before assuming permanent debt fits.

CRE Funding Hub provides education and inquiry routing—not credit decisions.

Early office conversations frequently focus on physical and economic occupancy, WALT, rollover concentration in the next 24–36 months, and whether tenants are expanding, shrinking, or hybridizing space use. A building that is 90% leased with a 2-year WALT can be riskier than one at 80% leased with a 7-year WALT—depending on tenant quality and mark-to-market rents.

Capital plans should address deferred maintenance, elevator/HVAC life cycles, amenity upgrades, and TI/LC needed to retain or replace tenants. Optimistic rent-growth assumptions without leasing evidence usually get challenged. Sublease overhang in the submarket can pressure asking rents even when your rent roll looks fine on paper.

Location still matters. Suburban medical office serving Anchorage, AK 99501 will not share CBD return-to-office dynamics of a large coastal market. Use local lease comps and avoid treating national headlines as your underwriting file.

Illustrate coverage with the DSCR calculator and income with the NOI calculator. Results are worksheets only.

Traditional office files often stress flight-to-quality themes, floor-plate efficiency, parking, and whether rents are above or below market. Medical office files more often emphasize healthcare tenant covenants, outpatient utilization context, specialized buildouts, and sometimes different buyer pools.

Neither category has a single national leverage rule on a website. Some capital sources have paused certain office types while remaining open to MOBs or well-leased suburban product; others evaluate deal-by-deal. Do not invent program eligibility from marketing blogs.

When permanent debt is unavailable until leasing improves, sponsors may discuss bridge or preferred equity outside this page’s scope. Start with a clear occupancy narrative and compare structures with a professional. Permanent-style CRE context also appears on our commercial mortgage loans page.

Assume an office building with NOI of $1,200,000 and proposed annual debt service of $900,000. Base DSCR = $1,200,000 ÷ $900,000 = 1.33x.

A tenant paying $250,000 of net effective rent expires in 12 months. If the sponsor budgets eight months downtime and $400,000 of TI/LC (simplified as reducing that year’s cash available to support debt for stress education), effective support might fall sharply in a lender stress case even if trailing NOI looked healthy.

For a simplified worksheet, reduce NOI by the lost rent during downtime to $1,033,000 (illustrative) and DSCR becomes $1,033,000 ÷ $900,000 ≈ 1.15x—still before full TI cash impact. The point is not a precise forecast; it is that office files live and die on rollover math.
