How to Calculate ROI for Your First Rental Property
Charles Phanumphai • October 29, 2024
Whether you're a new homeowner considering turning your vacation home into an income-producing rental, or an investor eager to purchase your first rental property, understanding how to calculate the return on investment (ROI) is critical to ensuring your property is profitable. Calculating ROI allows you to assess whether your rental will generate positive cash flow, helping you make an informed decision.
What is ROI and Why is it Important?
Return on investment (ROI) is a metric used to evaluate the profitability of an investment. In the context of rental properties, ROI helps you measure how much return you'll earn relative to the cost of acquiring and operating the property. Understanding your ROI ensures that you’re making smart financial decisions and helps you assess how much cash flow (profit) you’ll generate after covering all expenses.
Key Metrics for Calculating ROI
Here’s what you need to know to calculate your ROI on a rental property:
1. Purchase Price
This is the cost you pay to acquire the property. It’s not just the listing price—you’ll also need to factor in closing costs, inspections, and any necessary repairs.
2. Down Payment
Most lenders will require a down payment, typically 20-25%, on an investment property. This is important because it impacts your loan amount, and ultimately, your monthly mortgage payment.
3. Financing Terms
Understand the terms of your mortgage: the interest rate, length of the loan (15 or 30 years), and whether it’s a fixed or variable rate. Your loan terms will impact the size of your mortgage payments, which will affect your cash flow.
4. Operating Expenses
Operating expenses include the recurring costs associated with running the rental. These typically include:
- Property Taxes
- Insurance
- Property Management Fees (such as Snow Capped’s management fees of 15% for long-term and 20% for seasonal rentals)
- Repairs and Maintenance
- HOA fees
- Utilities (if not covered by tenants)
- Vacancy Rate (the percentage of time your property may sit vacant without rental income)
5. Gross Rental Income
Estimate how much you can charge in rent based on the property type and market demand. You can use tools like Zillow or Rentometer to compare rent prices in your area. For example, if you’re renting out a vacation home, research the local market for seasonal rentals or short-term stays.
6. Net Operating Income (NOI)
NOI is calculated by subtracting operating expenses from your gross rental income. It gives you an idea of the profitability of the property before factoring in mortgage payments.
Formula: NOI=Gross Rental Income−Operating Expenses
7. Cash Flow
Cash flow is the actual profit you make after covering all expenses, including the mortgage. Positive cash flow means you’re earning more in rent than you’re paying out in expenses, while negative cash flow means the opposite.
Use Rental Calculators to Make the Process Easier
You don’t have to do all these calculations manually! Tools like BiggerPockets’ Rental Property Calculator allow you to input your numbers and get an instant analysis of your potential ROI. These tools are especially helpful if you’re new to real estate investing and want a quick yet comprehensive overview of your property’s financial potential.
Key Takeaways for First-Time Investors
- Do your homework: Thoroughly research local rental rates, property taxes, and other expenses before purchasing.
- Consider all expenses: Don’t overlook costs like property management fees, maintenance, and vacancies, which can eat into your profits.
- Focus on cash flow: Positive cash flow is the key to a successful rental property. Make sure your rental income exceeds your expenses.
- Leverage calculators: Tools like BiggerPockets’ rental calculator can save you time and provide a clearer picture of your investment’s profitability.
Converting your second home into an income-producing rental or purchasing your first investment property can be a great way to generate passive income. By calculating your ROI and understanding your cash flow, you can make informed decisions that set you up for long-term financial success.
All Under One Roof
Winter Park's aerial transit system is moving through a serious planning process, and if you're renting, buying, or owning property here, it's worth understanding where things stand. Locals have heard this before. The town's own website calls this vision three decades in the making, and most of us have watched it surface and disappear more than once. What's different now is the structure: a rezoned base area, a $2 billion master plan, Alterra on record financing the gondola, and for the first time, specific design concepts in front of Town Council.
Not Ready to Sell? Renting Could Be the Perfect Next Step.

Spring & Summer 2026: More Options, Less Risk
Charles Phanumphai, owner of Snow Capped Properties in Grand County, Colorado, recently shared insights on burnout, entrepreneurship, and long-term success in real estate. Charles explained that avoiding burnout starts with finding work you genuinely enjoy, while also intentionally creating balance through family time, travel, fitness, and experiences outside of work. As a business owner and father, he prioritizes being present with his children and setting healthy boundaries around work in the evenings. Charles’ journey into real estate began in 2000 when he purchased his first “house hack” while attending college. At the same time, he built a 20+ year career in IT and workforce management. Over the years, he combined those two backgrounds to create Snow Capped Properties — a vertically integrated company focused on long-term and seasonal rentals, property management, and real estate sales throughout Grand County. He credits much of his success to three key principles: analyzing data, taking calculated risks, and trusting the process. His IT background helped shape a data-driven mindset that allows him to make strategic decisions based on market trends, rental performance, and long-term investment fundamentals rather than emotion. He also emphasized that success did not happen overnight, but instead came through years of consistent, disciplined progress. Charles also discussed the importance of adaptability in today’s evolving real estate market and the value of building long-term relationships rooted in professionalism, transparency, and trust.

Why This New Credit Rule Is a Game-Changer for Renters—and Landlords
At Snow Capped Properties, we believe in fair, equal access to housing for everyone. Fair Housing laws are designed to ensure that all prospective tenants are treated equally—regardless of factors like age, family status, gender, religion, national origin, or disability. What does this mean for you? Simply put, rental listings and conversations should focus on the property itself—not the person applying. For example, you won’t see language like “perfect for families” or “ideal for professionals.” Instead, you’ll see descriptions such as “close to parks and amenities” or “easy access to commuter routes.” This ensures that no one feels excluded and that everyone has an equal opportunity to consider a home. You may also notice that accessibility is described in terms of features—like stairs or layout—rather than assumptions about who can or cannot live there. This approach keeps the process transparent and inclusive. Fair Housing standards apply everywhere, including online listings and social media. By focusing on facts, features, and location benefits, we help create a fair and consistent experience for all renters. At Snow Capped Properties, this isn’t just about compliance—it’s about doing what’s right. Our goal is to provide a respectful, transparent process and help you find a home that fits your needs. If you ever have questions, we’re here to help. Source: Based on educational material from The CE Shop Fair Housing Guide.
Grand County 1st Time Buyer Checklist
Vertical Integration and Real Estate Resilience - I recently had the opportunity to sit down with Will Carr on his podcast to share more about my journey building Snow Capped Properties in Grand County, Colorado—and how adaptability has been the key to navigating a constantly changing real estate market. One of the biggest inflection points for our business came after the East Troublesome Fire. While it was a devastating event for the community, it also created an unexpected surge in demand for insurance-funded relocation housing. That moment reinforced something I’ve always believed: in real estate, challenges often create new opportunities—if you’re positioned to respond. Why We Focus on Midterm & Seasonal Rentals - At Snow Capped, we’ve intentionally leaned into 6–9 month rental strategies. This allows us to serve ski-season demand in the winter and what I call “heat refugees” in the summer—people escaping hotter climates. This niche has allowed us to remain stable while many traditional short-term rental (STR) models have struggled. The Reality of Today’s Market - We’re seeing significant shifts in Grand County. Short-term rentals are facing pressure from oversupply and changing travel behavior, with many owners experiencing notable year-over-year revenue declines. At the same time, high interest rates and elevated home prices are pushing more people into renting—what I refer to as the rise of a “renter nation.” The Power of Vertical Integration - One of the most important decisions I made was expanding beyond property management into buying and selling real estate. This vertical integration allows us to guide clients through the entire lifecycle—whether they’re renting, holding, or selling—without needing to leave our ecosystem. A Bigger Picture Approach - If there’s one perspective I always come back to, it’s this: real estate rewards those who think long-term. When you zoom out over a 10–30 year horizon, short-term market fluctuations become much less significant, especially if your properties are generating consistent income and building equity. What Really Drives Success - Success in this business isn’t just about capital—it’s about people. Having the right local knowledge and relationships makes all the difference. At the same time, I believe in staying curious. Even as you become an expert in your field, you have to be willing to challenge your own assumptions and adapt when the market shifts. The “Good Life” Philosophy - At the end of the day, real estate is just a vehicle. The goal is financial independence—not just for wealth, but for freedom. Freedom to be present with your family, your community, and the things that matter most. Living below your means and staying in “learn mode” are two principles I’ve tried to carry throughout my journey. And of course, we wrapped things up with some fun—talking about superpowers, time travel, and whether we might one day live to 250. If you’re interested in the full conversation, I’d encourage you to check it out. It’s a deeper dive into how we’re thinking about real estate today—and where we see opportunities moving forward. https://www.youtube.com/watch?v=OLEcFg8_JxY
