Tenants tend to treat interest rate moves as a landlord-only problem — something that happens on the other side of the negotiating table and doesn't touch their lease at all. That's backwards. Rate hikes change landlord behavior, and landlord behavior is exactly what determines how far a lease negotiation moves.
Here's why it matters now. The Fed hiked rates on September 16 for the first time since July 2023, and the 10-year Treasury has climbed to just over 5% — up from the low 4% range this summer. That's raised the landlord's cost of capital across the board: new acquisition debt, refinance debt, even the opportunity cost of leaving space vacant while they wait for a better tenant. A landlord who bought or refinanced recently, or who has a maturity coming up in the next couple of years, is now underwriting every lease decision against a more expensive capital stack than they were six months ago.
Combine that with where the San Diego office market actually sits: vacancy at 13.4%, up 40 basis points year-over-year, with negative net absorption through the first half of 2026. That's not a market where landlords are turning away tenants. It's a market where a landlord facing refinance pressure has every incentive to prioritize a signed lease with a creditworthy tenant over holding out for a marginally higher rate from someone who may or may not show up.
This is the same principle that shows up in every negotiation I've been part of, on either side of the table: assurance of close is its own form of value. I've watched a seller pass on a lower offer from a buyer with certainty of close in favor of a higher offer from a buyer without it — and get burned when the "better" offer fell through and the property didn't trade again for years, eventually selling for less than the original certain offer would have delivered. Landlords remember that lesson too, especially right now. A tenant who can move fast, commit to term, and close without drama is worth more to a capital-stressed landlord than a tenant squeezing for the last dollar of concession while dragging the timeline out.
That doesn't mean roll over. It means know what you're actually negotiating with. Before you go into a renewal or new lease conversation, find out what you can about the landlord's capital position — when they bought, whether there's a refinance on the horizon, whether the building has traded hands recently in a way that suggests fresh, more expensive debt. That's often findable through public record or just asking the broker directly. A landlord with a maturity wall coming is going to value term certainty and a clean credit tenant far more than one who owns free and clear or is sitting on cheap, long-fixed debt from years ago. Same market, same vacancy rate, completely different negotiating posture depending on that one fact.
The rate environment doesn't hand tenants leverage automatically. It hands leverage to tenants who understand what it's doing to the person across the table, and who show up able to offer the one thing a capital-stressed landlord actually needs right now: certainty.
