BigM) When did you start your current research/work on the research topic? Please describe the focus of the research as well and please be specific?

Dadi: I started research in geospatial technology in 2012 with Geo engineering department, Andhra University. The focus of my research is the use of satellite remote sensing, geographic information systems (GIS), and global positioning systems (GPS) in monitoring and managing natural disasters. I started version in 2016 and focuses on the importance of creating public awareness, improving capacity-building and resilience, and implementing technology-driven disaster management strategies to reduce the loss of human life and property caused by disasters. The research also highlights the value of geospatial technologies in creating detailed maps and in developing disaster preparedness and mitigation measures. It seems that the research includes case studies examining the use of remote sensing, GIS, and GPS in the management of various types of disasters, including cyclones, coastal erosion, and industrial disasters. Also, my research on-point focus is the development and use of a system called Hydrospatial Analysis Information System (HAIS) for the spatial analysis and assessment of groundwater quantity and distribution. The research also compares the performance of HAIS to other software tools for groundwater analysis in terms of processing time and memory occupation. The research seems to involve the analysis of software requirements and technical specifications for HAIS, as well as the design of the system’s overall flow and algorithms.

BigM) Why did you start your current research? Please be specific and give any relevant dates/years.

What motivated you?

Dadi: As a resident of India, I have always been concerned about the issue of declining groundwater levels in some parts of the country. In my home region, access to clean drinking water and sufficient water for agriculture has always been a challenge, and I have seen first-hand the impact that this can have on communities and the environment. However, it wasn’t until I learned more about the challenges faced by some parts of the country with low levels of groundwater that I became motivated to try and find a solution to this pressing problem. It is indeed the case that some parts of India have low levels of groundwater resources, which can be a challenge for meeting the water needs of the population for drinking and agriculture. Over-extraction of groundwater, inadequate rainfall, and climate change are among the factors that have contributed to declining groundwater levels in certain parts of the country.

BigM) What were you doing before you started your current research?

Dadi: After completing my undergraduate studies, I decided to pursue a master’s degree, with a focus on using information and communication technologies I was a senior full stack web developer at CSX. Prior to that, AgFirst Farm Credit Bank, Chubb Insurance, a Equifax, Retail Insight-Crossmark. Proven track record of creating and implementing complex technology solutions. I was interested in exploring the use of geographic information systems (GIS) and other geospatial technologies to map and understand the spatial distribution of groundwater and to identify ways to manage and protect these vital resources.

BigM) If your childhood or early family life has informed your choice in terms of your life as a researcher/scientist and/or the focus of that work, please let us know of any common themes?

Dadi: As the son of a food and adulteration inspector in Andhra Pradesh, India, my father has always emphasized the impact of contamination and pollution on human health and the environment, including specific health risks associated with consuming contaminated water. He has taught me about the ways in which the environment can affect human life and the earth as a whole.”

By researching the types of contamination present in ground level water sources in the region, it may be possible to identify patterns in the types of health problems that are being experienced by the population and guide efforts to address these issues. It relates to ground level water resources, is to identify the sources of contamination and pollution in the region. Understanding the causes of these issues can help policymakers and community leaders develop strategies for mitigating or eliminating them, which can protect the health of those who rely on ground level water sources for drinking, cooking, and other daily needs.

BigM) How did Covid affect the research you did for this most recent report in particular? If it did affect it, please be specific?

Dadi: One major impact has been the increased demand for hand sanitizer and disinfectant products, which has led to a shortage of isopropyl alcohol, a key ingredient in many of these products. This shortage has in turn led to the use of alternative chemicals, such as methanol, to make hand sanitizer. Methanol is toxic if ingested and can cause blindness or death. There have been instances of people drinking hand sanitizer, mistaking it for alcohol, and becoming sick as a result. This has highlighted the importance of properly labelling and storing cleaning and disinfectant products, especially in places where children or vulnerable individuals may be present. Another impact of the pandemic has been the increased strain on water and wastewater treatment systems due to the increased use of cleaning and disinfectant products, as well as the influx of personal protective equipment such as face masks and gloves, which can clog pipes and equipment.

BigM) Please describe those who will be helped by your work; please describe type of industry/person, locations, any other “goals” you have for the work you did in your research paper?

Dadi: My research would be of benefit to a variety of industries and individuals working in the field of natural disaster management and water resource management. This includes government agencies, non-profit organizations, private companies, and researchers and academics working in related fields. The research will be particularly relevant for individuals and organizations working in regions prone to natural disasters, such as cyclones, coastal erosion, and industrial accidents, or in regions with low levels of groundwater resources and challenges in meeting the water needs of the population for drinking and agriculture. Also, my research is of interest to professionals in the field of hydroinformatics and geospatial technologies, as it involves the use of GIS and other geospatial technologies for mapping and understanding groundwater resources. .The implementation of this system not only improves the performance and efficiency of the clients but also optimizes the use of network resources for the benefit of all stakeholders.

Royal York Property Management And Nathan Levinson On Building Stable Rental Portfolios In A Volatile Market

Published

December 11, 2025

Matthew Wiles

Across North America, Europe, and much of the world, rental housing is caught between two pressures. On one side are tenants facing record affordability challenges. On the other side are landlords seeing operating costs, interest payments, and regulatory complexity move in the opposite direction.

Recent analysis from Canada’s national housing agency shows how tight conditions still are. The average vacancy rate for purpose-built rentals in major Canadian centres rose to about 2.2 percent in 2024, up from 1.5 percent a year earlier, but still below the 10-year average despite the strongest growth in rental supply in more than three decades.

At the same time, higher interest rates have pushed up the cost of acquiring and financing rental buildings, which has slowed transactions and made many projects harder to pencil out.

In this environment, the question for landlords and investors is less about chasing maximum rent and more about building stability. That is where Royal York Property Management and its founder, president, and CEO Nathan Levinson have drawn attention.

From a base in Toronto, Royal York Property Management manages more than 25,000 rental properties, representing over 10 billion dollars in real estate value, and operates across Canada, the United States, and parts of Europe. Levinson also sits on a Bank of Canada policy panel focused on the rental market, where he provides data and on-the-ground insights about rent trends and landlord stress.

For many smaller property owners, his model has become a reference point for how to treat rental housing as a structured financial asset rather than a side project.

Rental housing under pressure from both sides of the balance sheet

In many countries, the basic rental story is the same. Construction of new rental housing has climbed, yet demand still runs ahead of supply in most major cities. In Canada, overall rental supply grew by more than 4 percent in 2024, the strongest increase in over thirty years, while vacancy rose only modestly.

At the same time, borrowing costs have moved sharply higher compared with the pre-pandemic period. Research shows that elevated interest rates have reduced the profitability of new multifamily deals and slowed investment activity, even as structural demand for rental housing stays strong.

For small and mid-sized landlords, that tension shows up in a simple way. Mortgage payments, taxes, insurance, and maintenance rarely move down. Rents move up more slowly, and in many jurisdictions they are constrained by regulation or market realities.

Levinson’s view is that this gap will not close on its own. Landlords who want to stay in the market need more predictable income, tighter control of costs, and clearer systems for dealing with risk.

A property management model built for volatility

Royal York Property Management did not start as an institutional platform. Levinson’s early clients were owners of single condominiums, duplexes, or small buildings who were struggling with irregular rent payments, surprise repairs, and complex rental rules.

Instead of handling each property ad hoc, he built a standardized operating model that treats every door as part of a wider portfolio. Each unit sits on a centralized platform that records rent, arrears, lease expiries, maintenance tickets, and legal actions. Owners see real-time statements and performance metrics rather than waiting for year-end reports.

That structure, combined with an internal maintenance and legal team, is designed to handle stress rather than avoid it. When markets are calm, the system may look conservative. When conditions worsen, it is what keeps owners in the black.

“Execution is everything” is how Levinson often frames it in interviews.

Turning rent into a more predictable income stream

The feature that first drew many investors to Royal York Property Management is its rental guarantee program in Ontario. Under this model, landlords receive their rent even if a tenant stops paying. RYPM takes responsibility for legal proceedings, arrears recovery, and re-leasing the unit, while the owner continues to receive income.

Independent profiles of the company describe this as one of the first large-scale rental guarantee frameworks in the Canadian market, and note that the firm manages tens of thousands of units under this structure.

The guarantee itself is closely tied to local law and does not transfer directly into every jurisdiction. The underlying logic, however, is straightforward:

Treat unpaid rent as a recurring and manageable risk rather than an occasional shock.
Price that risk into a clear product instead of handling each case informally.
Use scale, legal expertise, and data to keep default rates low and resolution times shorter.

For landlords who are facing mortgage renewals at higher interest rates, having a more stable rent stream can be the difference between holding a property and being forced to sell. That is one reason rental guarantee models have started to attract interest from investors outside Canada who are watching RYPM’s approach.

Using technology to see risk earlier

Behind the guarantee and the day-to-day operations is a technology stack that tries to surface problems before they become crises. Royal York Property Management’s internal platform uses data from payments, maintenance, and tenant behavior to flag risk signals and operational bottlenecks.

Examples include:

Tenants who move from on-time payments to repeated short delays.
Units where small repair tickets point to a larger capital issue ahead.
Buildings where complaint volumes suggest service gaps or staffing problems.

Rather than treating these as isolated events, the system aggregates patterns across thousands of units. That allows management to decide whether a problem is individual, building-specific, or systemic.

Levinson has also pushed this data outward. As a member of the Bank of Canada’s rental policy panel, he provides anonymized information on rent collection, defaults, and renewal behavior, which feeds into broader discussions about financial stability and housing policy.

The same data that protects a landlord’s cash flow in one building helps central bankers understand how higher rates are affecting thousands of households.

Why the Canadian case matters for global landlords

Several recent reports underline how closely rental markets are now tied to national economic performance. Tight rental supply and high rents are feeding inflation in many economies. At the same time, higher borrowing costs are discouraging new construction, which risks prolonging shortages.

This feedback loop is especially hard on small landlords. Many own only one or two properties and have limited room to absorb higher mortgage payments or extended vacancies. Analysts in Canada and abroad have warned that some owners are at risk of default as their loans reset at higher rates.

In that context, the Royal York Property Management model offers three lessons that travel across borders:

Standardization protects both sides. Clear processes for screening, rent collection, maintenance, and legal steps reduce surprises for owners and tenants at the same time.
Risk pooling is more efficient than one-off crises. Handling arrears, legal disputes, and vacancies inside a structured system is less costly than improvising each time.
Operational data belongs in policy conversations. When policymakers have access to real rental data rather than only mortgage statistics, interventions can be better targeted.

It is not an accident that Levinson’s work now sits at the intersection of private property management and public financial policy.

What everyday landlords can borrow from the Royal York playbook

Most landlords will not build a 25,000-unit management platform. Many will never interact with a central bank. The core ideas behind Nathan Levinson’s approach are still accessible to smaller owners that manage a handful of properties.

Three practices stand out.

First, treat every rental unit as part of a simple portfolio. That means using a consistent template to track rent, arrears, expenses, and vacancy days for each property, then reviewing it on a schedule instead of only when something goes wrong.

Second, write down the rules for risk in advance. Late-payment steps, repayment plans, documentation standards, and maintenance response times should exist on paper, not only in memory. Royal York’s experience suggests that clear rules reduce conflict, because everyone knows what will happen next.

Third, invest in service as a protective layer. Multiple independent profiles of RYPM point out that faster response times and transparent communication reduce tenant turnover and protect building condition, which in turn supports long-term returns.

For landlords and investors trying to navigate today’s volatile rental markets, the message from Royal York Property Management and Nathan Levinson is surprisingly simple. You cannot control interest rates or national housing policy. You can control how organized your portfolio is, how clearly you manage risk, and how consistent your operations feel to the people who live in your buildings.

For many, that shift from improvisation to structure is what will decide whether their rental properties remain a source of wealth or turn into a source of stress.
