Formula Explanation

GRM = Property Price / Annual Gross Rent

Worked Example

Example: A $300,000 property renting for $2,500/month has an annual gross rent of $30,000. GRM = $300,000 / $30,000 = 10.0x. This means it takes 10 years of gross rent to equal the purchase price — compare this across similar properties to find the best deal.
