Gross Rent Multiplier (GRM)
Purchase price divided by scheduled annual gross rental income.
Methodology v1.0Effective 2026-08-23Last reviewed 2026-08-23
How this is calculated
GRM = purchase price / annual scheduled rent
Oycora does not present GRM as a profitability or investment-quality score.
Why it matters
GRM is a quick price-to-rent screen before operating expenses and financing are considered.
What is included
- Purchase price
- Scheduled annual rental income
What is excluded
- Vacancy
- Other income
- Operating expenses
- Financing
- CapEx
Assumptions and limitations
- GRM is intentionally coarse and should not replace a complete analysis.
