High-quality tenants are the backbone of a thriving rental market.

From search to settlement, every step is self-service, including ID verification, self-guided tours, direct video communication with landlords, background checks, eSign, auto payment, and smart lock permission grant.
Adding a property is the only required task for house providers. Invest in homes like stocks, and earn dividends effortlessly.
Rental house vacancy periods are too long, averaging 42 days (Zumper), primarily due to scheduling mismatches between house providers and tenants. Self-guided tours can significantly reduce this period. According to Rently, Willow Bridge Properties experienced a 75% reduction in time on market, with 30% of leases resulting from self-guided tours [1]. However, self-guided tours are not widely popular due to security concerns and smart lock barriers.

My name is Sung-Fu Han, and I've been a software engineer and part-time landlord in Taiwan for the past 10 years. I manage properties scattered across Taipei City, New Taipei City, and Kaohsiung. However, the challenges of in-person property tours have led me to embark on an exciting new venture.
Taipei's notorious traffic has proven to be a nightmare, making it a struggle to travel from one rental property to another. Even when I manage to arrive on time, tenants sometimes cancel the room tours for various reasons, leaving me feeling frustrated and inefficient.
To address this issue, I believe that in-person room tours are not only inefficient but also impractical, especially when landlords are not always available at the property. What if they're on vacation and a potential tenant wants a tour? That's when I had a revolutionary idea – self-guided tours! This would allow tenants to explore the property at their convenience without the need for me to be physically present.
However, I understand the safety concerns associated with self-tours, especially in well-decorated properties where the risk of damage or theft is higher. Installing web cameras to monitor the tours seems like a solution, but it introduces extra efforts, and tenants may worry about their privacy even after the cameras are removed.
To overcome these challenges, I'm introducing the "Zero Installation Self Tour." We ensure tour safety only depends on tenant's phone camera. During the tour, we kindly request tenants to grant permissions for their front and rear phone cameras. This enables us to stream the captured footage to an advanced AI-driven malicious event detection system, which aids in identifying any potential instances of missing or damaged objects. Moreover, the stream can also be utilized by tenants to provide evidence of their innocence if need.
But my vision doesn't stop there. I'm driven by a larger dream – to fully automate the entire rental process and turn renting a house into a genuine passive income stream.
To achieve this, I will automate each part in rental life cycle. I've divided the rental process into three essential parts: before-contract, in-contract, and after-contract. Before-contract services involve recruiting the right tenants through self-tours, identity verification, background checks and eSign. In-contract features include monthly rent payment systems, and maintenance ticket system to address any issues promptly. After-contract includes credit system and room rollback service to ensure the property can rejoin listing automatically.
I firmly believe that automating the entire rental process is feasible, and self tour is last mile. It's surprising that there's no holistic solution available in the market yet. With this conviction, I've decided to take the lead and turn my vision into reality. My mission is to make entire rental process more efficent. Together, we'll make renting a house a true passive income.
I'm thrilled to show that despite not being typical young, university-dropout founder, I've taken the traditional route - completing my education and gaining years of work experience. Now, I'm ready to chase my dream and start my own company. This dream is a glowing ember within me, and with persistence, it will ignite into a blazing success!
Q1: Why do you ask tenants to use their phones for a video tour instead of installing a camera in the room?
A: There are several reasons for this approach. Firstly, having a camera in the room can make tenants feel insecure, a feeling that might persist during their stay. Using their phones, tenants can choose specific areas to focus on, and later compare these with other videos. This method also avoids the need for landlords to install additional equipment. Most importantly, it helps tenants feel safer and more in control of their privacy.
Q2: Why prefer physical tours over virtual tours?
A: Virtual tours like Matterport offer a great preview, but they fall short in capturing the essence of a property. Tenants often need to experience aspects like the neighborhood vibe, natural light, and feel of the space in person before making a commitment. That's why, despite the convenience of virtual tours, physical self-tours remain crucial for final decision-making.
Q3: What is the different between spaceFlow and other property management software such as appfolio, doorloops, turbotenant and hemlane?
A: spaceFlow distinguishes itself in the property management sector by prioritizing the rental experience of highly qualified tenants. While traditional software solutions cater to landlords and property managers, 50% property owners still choose self-management, indicating a gap that existing platforms do not address. spaceFlow believe qualify tenants deserve express rental experience. Qaulified tenants are who meet strict qualifications, including ID verification, credit card linkage, a credit score above 700, a clean criminal record, verified income, and no history of eviction. By focusing on these tenants, who are effectively single-unit property managers, spaceFlow enhances their autonomy, strengthening trust with landlords and facilitating remote property management. This shift to tenant-centered features promises to attract landlords by providing them the assurance of a responsible occupant and a hands-off management approach.
Q9: How to make self tour everywhere?
GPT: Making self-guided property tours available everywhere involves a combination of technology, security, and logistical planning. Here's a general strategy to achieve this:
-
Develop a Reliable Technology Platform: Create or utilize an existing platform that allows potential tenants to schedule and access properties without needing a physical agent present. This platform should handle scheduling, identity verification, and secure access.
-
Implement Secure Access Systems: Install smart locks or lockbox systems that can be controlled remotely. These systems should allow access only to verified individuals and at the scheduled times.
-
Identity Verification: Ensure that all users of the self-tour service undergo a robust identity verification process. This could include submitting government-issued ID and a current photograph, and possibly credit card information for security purposes.
-
Real-time Monitoring: Use technology like computer vision or real-time surveillance to monitor tours. This ensures safety for the property and can provide landlords with peace of mind.
-
Feedback and Reporting Mechanisms: After the tour, have an automated system to collect feedback or reports from the potential tenant. This can help in improving the experience and addressing any issues immediately.
-
Marketing and Partnerships: Collaborate with property listing sites, real estate agents, and property management companies to offer self-tour options as a part of their services.
-
Legal Compliance and Insurance: Ensure all activities comply with local real estate laws and regulations. Also, consider insurance to cover any liabilities that might arise from self-tours.
-
Customer Support: Provide excellent customer support to handle any issues, questions, or emergencies during the self-tour.
-
Continuous Improvement: Collect data and feedback to continuously improve the self-tour experience, security, and technology.
-
Scalability Plan: Have a clear plan for scaling the service, including expanding to new locations, managing increasing numbers of tours, and ensuring consistent quality and security as you grow.
Implementing self-tours everywhere is a complex task that requires careful consideration of security, technology, and user experience, but with the right approach, it can significantly enhance the property rental process.
