Performance
Quarter after quarter, the company has demonstrated strong same-store revenue and net operating income growth.
Revenue Rate Management
In seeking to maximize the performance of our properties, we employ our proprietary revenue rate management program, which helps us to analyze, adjust, and set our move-in and existing tenant rental rates on a real-time basis across our portfolio. Among other technologies, we employ internet data scraping of our local competitors’ move-in rental rates to enable us to proactively respond and take advantage of changing market conditions across our portfolio.
Brand Recognition and Digital Marketing Prowess
We have registered the trademark and developed the brand “Global Self Storage.” We have developed a corporate logo and have incorporated it on all of our on-site signage, advertising and other marketing materials. This branding process has included the creation and development of the www.GlobalSelfStorage.us website, whereby prospective customers can rent a storage unit or learn about the features of any of our properties in their various locations. We continue to develop the Global Self Storage online presence through advertising and search engine optimization.
Focus on Quality Tenants
Attracting and retaining high-quality, long-term tenants is a top priority for Global Self Storage and we strongly believe in tenant quality over tenant quantity. We prioritize tenant quality both in our marketing and operational efforts. In our marketing efforts, we have seen success in our referral marketing program, through which our tenants may recommend Global Self Storage to their family, friends, and colleagues. This generates new tenant inquiries for high quality new tenants. As part of our initiative to build a higher quality overall tenant base we often target our promotions to credit card paying customers, who rent for longer duration and and accept greater rental rate increases. We have a strong digital presence generating new tenant inquiries and also believe that our property managers’ attention to detail—maintaining security, cleanliness, and attentive customer service—is essential to attracting high quality tenants. As a result of these efforts, average same-store tenant duration was ~3.0 years as of December 31, 2020.
Customer Service Management
Customers choose us because of our high quality service and facilities. All of our properties have on-site property managers who are committed to delivering the finest customer service. We utilize a customer call center to handle telephone inquiries from current and prospective tenants whenever our store managers are not available. We seek to deliver convenience and high-quality customer service to our tenants as well as maintain clean and secure properties at all times. At Global Self Storage, Security is Our First Prioritysm and we implement 24/7 video security and keypad-coded gate access at our properties. Each of our properties also features a rental and payment kiosk available 24 hours a day, seven days a week, where prospective tenants can rent a unit and current tenants can pay their rent. Our goal is to make the customer experience as pleasant and hassle-free as possible.

Frequently Asked Questions (FAQs)
Here are some of the most common questions about third-party management and partnering with Global Self Storage. If you have any additional questions, feel free to contact us anytime via email at thirdpartymanagement@globalselfstorage.us or by phone (317) 597-5052.
There are many reasons why an owner might want to consider a third-party management company. Owners should consider a third-party management company if they are new to the industry, looking to expand, or scaling back and looking for someone to take care of their property. Global Self Storage works closely with each owner to discuss the owner's situation and goals to find the best outcome to maximize profits. Owners that are interested in hiring a third-party management company should think about their own expertise and time in relation to a third-party management company's experience and past performance, vendor sources, and scalability. Owners should consider qualitative factors when considering a third-party management company's attractiveness but also quantitative performance results to determine competency and subsequently decide what company will be able to manage a property best.
Owners should look for a third-party management company that consistently delivers top-ranked performance results. Almost all third-party management companies will talk about how they can reduce hassle, increase occupancy, and/or can run the facility better than the owner, but owners should look at the bigger picture to find a company whose vision, mission, and values align with the owners' short and long-term objectives. Occupancy is only one component of the operator success equation. Owners need to look at the sophistication of the third-party management company’s operations, including the strength of its online presence and digital marketing, ability to drive rates and achieve optimal high occupancy, local managerial staff availability and experience, and corporate support. When selecting a third-party management company, it is important to understand how the management company operates. A good management company will have a proven system in place and significant expertise leading to demonstrated success and positive performance results.
Global Self Storage is interested in managing both existing and development properties. If you have a development property, it is preferable to become involved in the process early on, so that we can serve as an operational consultant to advise on unit mix, signage, marketing, technology, and other factors and considerations.
We typically do not have any strict geographic or size limitations when considering suitability for management, but we want to make sure that the property and our platform will mix well so that we can help the property succeed. We will determine suitability for management based on Global Self Storage's mission—we seek to manage properties where our highly-effective professional management and best practices can improve operations. At the same time, we are always open to discussing the potential of managing any property.
Absolutely! Creating strong partnerships is extremely important to us and given the scope of our operation, we make no distinction between wholly-owned, joint venture, or third-party managed properties. While we review every property individually when it comes to optimizing operations and marketing efforts, these considerations and the review methods will be the same across all properties. Once a property is integrated, it will be considered a Global property and third-party owners will benefit from our strong brand.
The transition time can only be defined on a case-by-case basis. Our team works closely with the owner to make sure that the transition is seamless and integration happens smoothly. Contact us for more information.
Set up costs are charged to the property on a need-based basis and vary for every property. In many cases, the necessary items are already available at the site and new items are not necessary. In addition, set up costs may, from time to time, be shared by Global Self Storage. Breakdowns of set up costs will be provided to the owner prior to any engagement.
We will put together a customized budget for your property to illustrate what your costs would be. We can also give you a projection of occupancy, discounts, and revenues under our management platform. Using results from comparable properties, we can accurately forecast your costs and potential cost savings. Global Self Storage will handle the accounting for your property. We can provide you with sample financials to demonstrate what is provided to third-party owners and accounting reports can also be emailed per your request. Owner distributions are typically done by ACH to the owner’s preferred bank account unless otherwise requested.
By partnering with Global Self Storage, third-party owners will benefit from the strength of our brand and our national presence and prominence. As part of transitioning your property to Global Self Storage and integrating with our brand, certain set up and branding elements, including exterior signage and interior branding and marketing assets, will need to be addressed and/or changed. Set up costs can vary based on the property.
Yes, we will definitely consider current site managers and staff if the property becomes managed by Global Self Storage. We realize that current managers might already have developed important knowledge about the property and created relationships with current customers, and this will be considered when evaluating property managers' experience and fit.
