One of the most important financial decisions you will make in your life is the purchase of a home. Should you keep renting and invest your additional cash? Should you buy a property now to beat inflation and home prices in the future? What are some of the decision factors - financial and lifestyle - that you should consider before purchasing a home? We’ve developed the Investant Rent or Buy Tool to help answer some of these questions!
Rent or Buy Methodology
From a financial perspective, there are two main components to the decision to Rent or Buy: Expenses and Opportunity Costs. Using our tool, in the graph on the right can be seen the average monthly expense by year if the home were to be purchased versus if you were to rent. This includes all of the forecasted expenses for each year over the course of the scenario, distributed across 12 months per year.
Try adjusting the mortgage term to 15 years, and entering that you will live in the home for 25 years to see how your monthly expense to live in the home completely falls away when the mortgage is paid off while renting prices continue to climb!
Directly below the graph lies more information on the cumulative costs of buying versus renting and the opportunity costs of each. If you were to rent, as an example, you will likely have additional cash on hand from smaller monthly payments and not needing to make the down payment on a mortgage loan. This additional cash can be invested and the proceeds from doing so can be seen as an opportunity cost to purchasing the home. However, buying the home will allow you to build equity through paying off the principal of the loan and through the appreciation of the home’s value. This can be seen as an opportunity cost to renting.
How to Use the Tool
Decision Inputs
The first section contains the essential inputs for your analysis:
- Property Value: Enter the price of the home you're considering
- Down Payment: Input how much you plan to put down
- Living Years: Specify how long you plan to stay in the home
- Monthly Rent: Enter the comparable rental cost in your area
Growth Rates | These optional inputs help forecast future values:
- Annual Home Growth Rate: Expected appreciation of the property
- Annual Rent Growth Rate: Projected increase in rental prices
- Annual Investment Return: Expected return on invested savings
Other Expenses | These optional details help refine the tool to your situation: For Renting:
- Monthly utilities
- Broker fees
- Rental insurance
For Buying:
- Mortgage rate and term
- HOA fees
- Property tax rate
- Maintenance costs
- Purchase and selling costs
- Homeowner's insurance
- Tax considerations
- Renovation budget

Understanding the Results
The tool provides several key insights:
- A comparison of average monthly cost based on how long you’ll live in the home
- An interactive graph showing the cost comparison over time
- Total costs for both renting and buying scenarios
- Investment returns from renting vs equity gained from buying
Beyond the Numbers: Lifestyle Considerations
While financial analysis is crucial, the rent or buy decision extends beyond pure economics. Home ownership can provide:
- Stability and control over your living space
- Freedom to customize and renovate without landlord approval
- A sense of community and belonging
- Pride of ownership and accomplishment
- Protection against rent increases and potential eviction
However, renting offers its own advantages:
- Flexibility to relocate for career opportunities
- Less responsibility for maintenance and repairs
- Lower upfront costs and financial commitments
- Simplified budgeting with predictable monthly expenses
Your decision should ultimately align with both your financial goals and personal values. Use our tool to understand the financial implications, but remember to consider how each choice fits into your broader life plans and aspirations.
