How Inflation Helps Landlords
- Fixed mortgage vs. rising rents: A 30-year fixed at $1,200/month stays $1,200 forever. Market rent rising 4%/year from $1,600 reaches $2,366 in year 10. The spread between fixed cost and market rent grows annually.
- Debt erodes in real terms: $200,000 mortgage in today’s dollars is equivalent to $135,000 in purchasing power in 10 years at 4% inflation.
- Property value rises with inflation: A $250,000 property appreciating 4% annually reaches $370,000 in 10 years.
- Depreciation compounds relative to rent: Fixed depreciation ($9,090/year on a $250K building) becomes increasingly valuable as rental income rises with inflation.
How inflation compounds the landlord cash flow advantage ($240K property, 6.5% rate, 4% inflation)
| Year | Monthly Rent (4% inflation) | Mortgage (fixed) | Monthly Surplus Pre-Expenses | Spread Growth |
|---|---|---|---|---|
| Year 1 | $1,600 | $1,098 | $502 | Baseline |
| Year 5 | $1,946 | $1,098 | $848 | +$346/month |
| Year 10 | $2,368 | $1,098 | $1,270 | +$768/month |
| Year 20 | $3,503 | $1,098 | $2,405 | +$1,903/month |
Landlords who bought in 2019 at $1,400/month rent saw that unit renting for $1,900–$2,100 by 2023 — a $500–$700/month improvement in cash flow with zero change in fixed mortgage costs. Inflation was the catalyst; the fixed-rate mortgage was the mechanism.
How Inflation Hurts Landlords
The downside: high inflation triggers rate increases that make new acquisitions expensive (7%+ mortgage rates). Maintenance and repair costs rise with inflation. Insurance premiums rising 15–20% annually (2022–2024) add expense pressure. Net: existing properties win; new acquisitions at peak costs are harder to cash-flow.
