CMBS Conduit Capital Focuses Heavily on Multifamily, Office Sectors

# CMBS Lenders Tighten Equity Requirements Even as Rates Fall

Commercial mortgage-backed securities lenders are pushing borrowers to inject more of their own capital into deals, despite a year of declining interest rates. The shift reveals a lending market that has sharpened its focus rather than loosened its grip.

Data from CRED iQ tracking conduit CMBS activity shows lenders concentrating heavily on multifamily and office properties. These two sectors now dominate loan originations, but buyers and sponsors face steeper equity requirements across the board. Loan-to-value ratios have compressed, meaning that borrowers can't leverage as much debt relative to a property's value, even though the cost of that debt has fallen.

This dynamic matters for different players in distinct ways. For sponsors seeking to acquire multifamily or office buildings, lower rates would normally signal easier financing. Instead, they face demands to put down larger equity checks. A buyer who could have financed 75 percent of a deal's value a year ago might now be asked to cover 70 percent with cash or equity partners. That tightens returns and forces sponsors to find richer capital sources or walk away from acquisitions.

Sellers benefit from this environment in one respect. Buyers who can access CMBS financing now represent higher-quality capital. The market has self-selected for sponsors with deeper pockets and stronger balance sheets. This supports valuations for premium properties in primary markets, though marginal assets face higher barriers to sale.

Multifamily continues its reign as the dominant CMBS asset class. Despite recent rent growth slowdowns in gateway markets like New York and Los Angeles, lenders remain comfortable lending on apartment buildings. The sector's predictable cash flows and demographic tailwinds keep it attractive. Office lending, by contrast, reflects the market's cautious stance on a sector grappling with hybrid work and elevated vacancy rates. When lenders do finance office, they demand more equity protection and stronger sponsor track records.

The rate environment creates a peculiar moment. The Federal Reserve cut rates, tightening spreads on CMBS bonds. Borrowing costs fell. Yet lenders haven't responded by relaxing underwriting. Instead, they've used the rate decline to maintain disciplined pricing while extracting more skin in the game from sponsors.

For landlords managing existing properties, the tightening equity requirements matter less immediately. But refinancing risk looms. A property financed at a 75 percent LTV three years ago won't refi at the same leverage today. Owners approaching maturity must either inject capital, reduce proceeds, or accept fewer options from lenders. This pressure will intensify if the Fed pauses rate cuts or reverses course.

Tenants benefit indirectly from stricter CMBS underwriting. Lenders now demand higher reserve funds, better operating metrics, and proof of lease stability before advancing capital. Buildings financed through CMBS conduits typically operate with tighter management than those held by opportunistic buyers or undercapitalized sponsors. Stricter financing standards correlate with better-maintained properties and more stable ownership.

The conduit market has split into winners and losers. Trophy multifamily assets in supply-constrained markets attract aggressive competition among lenders. Secondary multifamily in declining rent markets finds fewer backers. Office that pencils out remains financeable for strong sponsors, but tertiary office faces potential dislocation. Class B and Class C assets across all sectors confront material headwinds.

CMBS lenders are not panicking. They are calibrating. Multifamily's stability keeps it in the bull's-eye, while office financing occurs only when sponsors bring meaningful equity cushions and demonstrable lease strength. The selectivity will persist as long as uncertainty over economic growth and property fundamentals remains.
