Questions & Answers
Q: Why is comparing mortgage payment to rent not a meaningful comparison?
Comparing mortgage payment to rent doesn't consider additional costs of owning, such as property taxes, maintenance costs, and the cost of capital, which are unrecoverable costs for homeowners.
Q: What is the 5% rule used for?
The 5% rule estimates the total unrecoverable costs of owning a home by multiplying the home value by 5% and dividing by 12. If the rent is lower than this estimate, renting is financially more sensible.
Q: What factors can affect the 5% rule?
Tax rates and portfolio asset mix can affect the 5% rule. For example, if investments are taxed, the aftertax return might be lower, reducing the cost of equity capital and potentially decreasing the total unrecoverable cost of owning.
Q: How does the 5% rule help in the rent vs. buy decision?
The 5% rule provides a simplified way to compare the financial aspects of renting and owning a home. If the rent is less than the estimated total unrecoverable costs of owning, it may be more financially sensible to rent.
