What does “gross rent multiplier” mean in real estate?

Gross rent multiplier, or GRM, is the relationship between a property's sale price or value and its gross periodic rent. Value equals gross rent multiplied by the market-derived GRM.

How is “gross rent multiplier” different from the closest wrong answer?

GRM uses gross rent and no operating expenses. Capitalization uses net operating income and a cap rate.

What is the Georgia-specific rule?

The exam must keep the periods consistent. A monthly GRM pairs with monthly rent, while an annual multiplier pairs with annual rent.

Mixing annual rent with a monthly multiplier produces an answer twelve times too large.
