Say Goodbye To Security Deposits

Security deposits remain one of the most overlooked and persistent financial barriers in the U.S. rental housing market. For low- and moderate-income households, they function less as a risk-management tool and more as a liquidity drain that weakens their financial stability before they even move in. For property owners, that same loss of liquidity increases the likelihood of missed rent, turnover, and eviction-related costs.

The irony is that security deposits were originally created to reduce risk . In today’s housing market, they are likely doing the opposite.

A 19th-Century Tool in a 21st-Century Market

Security deposits were introduced in the late 19th century, when rental housing was informal, leases were inconsistent, and landlords had few tools to assess or manage risk. A cash deposit provided a simple hedge against unpaid rent or property damage in a world without credit reporting, standardized underwriting, or modern insurance markets.

That logic may have made sense for the guy who was renting a room above his horse-and-buggy repair shop in 1886, but it no longer applies to the world we live in today.

In 2026, nearly two-thirds of low- and moderate-income renter households have less than $2,000 in their bank account. At the same time, the average required security deposit is roughly $1,000.

What this means is that we are asking millions of renters - who already struggle to make ends meet - to tie up half of their available savings before they set foot in their apartment.

This is, quite literally, horse and buggy thinking. And it has real consequences for renters and property owners alike.

Lower Liquidity. Higher Risk

Housing instability is not driven by chronic irresponsibiliy. It is far more often the result of thin margins.

When renters have less cash-flow liquidity at move-in, small disruptions (a car repair, a medical bill, a family emergency) can quickly escalate into a missed rent payment and increase the likelihood of eviction or turnover.

Properties with higher eviction and turnover rates incur higher bad debt and eviction related costs, lower levels of economic occupancy, and less predictable cash flow. Housing instability creates investment instability.

In practical terms, the traditional approach to mitigating leasing risk is now producing the opposite effect. By draining renter savings before they move in, security deposits increase the very risks they were designed to reduce.

Hello Technology. Goodbye Horse and Buggy.

Over the past several years, a growing number of multifamily property owners have begun replacing traditional security deposits with insurance-based alternatives.

Rather than requiring renters to essentially self-insure through a lump-sum payment, these models pool risk across portfolios and transfer it to regulated insurance structures. This approach was pioneered by LeaseLock, a financial technology firm that was founded in 2012.

LeaseLock replaces security deposits with an insurance-backed lease guarantee that protects owners against the same risks that security deposits were meant to cover: unpaid rent, damage beyond normal wear and tear, and early lease termination.

How Deposit Insurance Works

Instead of relying on an upfront cash requirement, LeaseLock uses data-driven underwriting and AI-enabled risk modeling to assess exposure dynamically. Machine-learning models analyze applicant and portfolio-level data such as income stability, employment patterns, rental payment behavior, and historical loss performance.

Risk is then pooled and insured across thousands of leases, rather than being borne individually by renters through immobilized cash.

From an owner’s perspective, this approach is often more protective than a traditional deposit. Security deposits are capped by law, eroded by inflation, and frequently insufficient to cover actual losses. Claims can be delayed, disputed, or not recovered at all. Insurance-backed guarantees, by contrast, provide higher coverage limits, predictable payouts, and cleaner recovery mechanics.

From a renter’s perspective, eliminating deposits preserves liquidity without increasing credit risk. The original function of the deposit - compensating for limited credit information and enforcement tools - is now handled through modern data, insurance mechanics, and portfolio diversification. Most importantly, the renter can keep more cash in their savings account where it can be used to cover more of life’s unexpected expenses.

Operationally, the benefits also compound. Deposit insurance eliminates escrow accounts, refund disputes, and compliance complexity. For operators, that means simpler administration, less operational risk, and lower overhead. They no longer have to administer thousands of separate escrow accounts. For renters, it keeps their rainy day fund funded and they no longer have to go through the time-consuming process of getting their deposit back when they move.

This model has now been deployed across millions of leases, demonstrating that it can scale across asset classes without sacrificing underwriting discipline.

Why This Matters for Renters, Owners, and Investors

When renters retain savings, they are more financially resilient. When households are more resilient, rent is more likely to be paid on time. When rent is paid on time, properties perform better. Stability at the household level translates directly into stability at the asset level.

Lower upfront costs also expand access. Renters can choose housing based on proximity to work, schools, and services - not just their ability to scrape together enough cash. That flexibility increases choice, reduces involuntary moves and supports longer tenancies, all of which further lowers turnover costs.

Innovations like deposit insurance strengthen renter liquidity, reduce the likelihood of missed rent payments, and lower eviction and turnover-related costs. All of these translate directly into property-level performance: steadier cash flow, lower operating volatility, and more predictable returns.

That connection matters because our ability to create and preserve more affordable depends on our ability to attract more long-term investment capital from pension funds, insurance companies, endowments, and other institutional investors that depend on long-term stability. They are not looking for short-term exits or concessionary returns. They are simply looking to meet their fiduciary responsibilities by investing in assets that generate consistent cash flow and risk-adjusted rates of return.1

Embracing The Future. Establishing Industry Standards.

Security deposits made sense in the 19th century. They do not make sense today because the risk they were designed to mitigate can be better managed through systems that reflect how the rental households of today experience financial stress - and how rental housing portfolios actually absorb loss.

The rationale for replacing security deposits with insurance-based structures reinforces the basic premise behind the industry standards for impact investing established by the Multifamily Impact Framework:

Financially stable renters create financially stable assets.

Embracing technology to modernize outdated practices like security deposits checks that box. It improves the financial health and stability of renters, it improves the financial performance of the building in which they live, and it offers tangible proof that impact-driven outcomes and investor returns are mutually dependent and not mutually exclusive.

Doing well means doing good. Doing both means doing more.
