The True Cost of Vacancy in High-Demand Markets
In a high-demand market like San Diego, it is easy to assume that a vacant unit is just a minor, temporary “hiccup.” With vacancy rates for multifamily properties hovering around 5.0% in early 2026, owners often feel confident they can find a new tenant quickly. However, to consider vacancy as strictly “lost rent” is inadvisable and can quietly erode your annual returns.
Considering this, what is the true cost? Simply put, vacancy is a ” multiplier effect“. In the foreground, one may notice changes such as the immediate loss of checks in the mail. In the background, however, an empty unit triggers a cascade of hidden expenses, operational friction, and long-term valuation risks. For the high-net-worth investor or family trust, understanding these numbers is key. After all, the difference between a property that merely exists and one that truly performs is a matter of preparing for every outcome.
The Empty Unit and Its “Hidden Math”
When a property is empty, the owner is hit by three distinct financial waves:
- Direct Income Loss: The most obvious, of course. At an average San Diego rent, every day a unit sits empty is roughly $70 to $90 in vanished revenue.
- Persistent Carrying Costs: Even with no tenant, the bills persist. You must continue paying utilities for showings, pay property taxes, and cover insurance premiums, all while the unit generates no income.
- The Turnover Spike: Every vacancy requires a “make-ready” phase. This includes professional cleaning, lock rekeying, and minor repairs that often cost between $1,000 and $2,500 per turn, depending on the unit size.
- The $100 Trap: Many owners hold out for an extra $100 in monthly rent, causing a unit to sit vacant for an additional 30 days. In San Diego, that one month of vacancy can cost you more than the entire annual gain from that rent increase.
Vacancy Threatens Property Value
For multifamily investors, the impact of vacancy is not just about monthly cash flow; it’s about Net Operating Income (NOI). Because property valuations are often tied to cap rates, a sustained increase in vacancy can lead to a lower appraised value.
While a unit remains vacant, your NOI decreases. If you are planning to refinance or sell in 2026, we urge you to consider that even a small percentage increase in your economic vacancy can result in a significant “paper loss” on your total asset value.
The Power of Proactive Management
At The Mendes Company, our core philosophy is that we manage properties as if we own them. At its core, this philosophy considers proactivity a top priority. Instead of waiting for vacancies to take place, we work to prevent the “vacancy spiral” before it starts. Our approach focuses on:
- Aggressive Retention: It is always more cost-effective and efficient to maintain a high-quality resident rather than finding a new one. We prioritize clear communication and fast maintenance in order to keep current tenant satisfaction high.
- Strategic Pricing: We use real-time market data to price units accurately, ensuring they lease fast without leaving money on the table.
- Fast-Track Turnovers: Our timelines strive to be both speedy and thorough. Our in-house maintenance team allows us to respond quickly and control costs, getting units back on the market in days, not weeks.
Stop the Threat Before It Starts

Whether you are overseeing a family legacy or scaling a high-net-worth portfolio, the right partner ensures your assets remain occupied, protected, and profitable.
