Frequently asked questions
What is a good gross rent multiplier?
Generally, a GRM between 4-7 is considered good, but this varies by location and property type. Lower numbers typically indicate better cash flow potential.
How is GRM different from cap rate?
GRM uses gross rental income while cap rate uses net operating income after expenses. GRM is simpler but less precise than cap rate calculations.
Should I use monthly or annual rent?
Always use gross annual rental income for GRM calculations. Multiply monthly rent by 12 to get the correct annual figure for accurate results.
