Summary

Those looking to minimize relocation costs often turn first to "zero security deposit and zero key money" (zero-zero) properties. While the initial costs certainly appear lower, there are reports of unexpected move-out expenses and even cases where the property quality itself is problematic. This article explains how zero-zero properties work, their advantages and disadvantages, and how to choose them while avoiding risks.

What Are Security Deposits and Key Money?

A security deposit is a deposit that covers rent arrears or room damage caused by a tenant. If there are no outstanding payments or damage when you move out, it is refunded. Typically, security deposits amount to 1-2 months' rent.

Key money is traditionally paid as a "thank you" gift to the landlord and is generally non-refundable. Historically, it was standard to pay 2-3 months' worth, but in recent years, even in the Tokyo metropolitan area, 1 month is common, and in rural areas, zero key money properties are becoming more prevalent.

Why Zero-Zero Properties Are Increasing

Against the backdrop of declining birth rates and rising vacancy rates, landlords and real estate companies continue to lower initial costs to secure tenants. Particularly for older properties or those far from stations, zero-zero conditions are often used as a way to differentiate from competitors.

Advantages of Zero-Zero Properties

The biggest advantage is a significant reduction in initial costs. With a standard rental, security deposit, key money, agency fee, and advance rent combined typically amount to 5-6 months' rent, but with zero-zero properties, this can be reduced to approximately 3 months.

For example, for a property with monthly rent of ¥70,000, standard initial costs would be ¥350,000 to ¥420,000, but with a zero-zero property, you would need only around ¥200,000. This is an extremely effective option for those with limited available funds or those needing to relocate urgently.

Risks and Considerations for Zero-Zero Properties

Risk of Higher Move-Out Costs

Without a security deposit, tenants must pay the full cost of repairs out of pocket when moving out. Minor repairs that would normally be deducted from the security deposit are billed in full for zero-zero properties.

Additionally, some landlords bill heavily for restoration to original condition to compensate for the lack of a security deposit. Even if a request violates Consumer Affairs Agency guidelines, tenants without knowledge may accept it at face value.

Guarantor Company Enrollment Is Often Required

In place of a security deposit as risk mitigation, most properties require enrollment with a guarantor company. An initial guarantee fee of 50-100% of monthly rent is charged, plus approximately ¥10,000-¥20,000 at renewal. This can result in a structure where "initial costs are low, but the total amount paid increases the longer you live there."

Pay Attention to Property Quality and Management Condition

Properties that struggle to attract tenants enough to require zero-zero conditions may have issues with location, facilities, or management. During a viewing, carefully check equipment functionality, cleanliness of common areas, and the management company's responsiveness.

Key Points for Choosing Properties While Minimizing Risk

First, always review special contract terms. Check in the lease agreement how "normal wear and tear" is defined for restoration upon move-out. If special terms such as "cleaning costs are tenant responsibility" or "complete flooring replacement is tenant responsibility" are written, they can become sources of trouble later.

Second, photographic and video documentation before moving in is important. Taking dated photos and videos of the entire room immediately after moving in allows you to prove "damage that existed before moving in" at move-out time.

Research the management company's reputation as well. Search for reviews of the management company on Google Maps and social media, and it's wise to avoid companies with many reviews mentioning "problems with move-out costs."

It's also important to compare based on total costs. Compare the "total cost"—including not just initial costs but also guarantor company fees, renewal fees, and estimated move-out costs—with standard properties that have security deposits and key money.

Summary

Zero-zero properties are an effective way to reduce initial costs, but it's important to comprehensively assess move-out costs, guarantor company fees, and management company quality. Rather than jumping at the low price alone, by carefully reviewing the contract terms before choosing, you can truly enjoy the cost benefits.

Even for those with limited relocation budgets, it is entirely possible to find a property that keeps initial costs down while offering peace of mind, as long as you wisely review the conditions.
