Buyer's guide

How to choose a gross rent multiplier calculator

When picking a GRM calculator, the core inputs are always property price and annual gross rent — any tool that handles those two numbers will give you the same ratio. Look for extras only if you need to solve for a missing variable or translate GRM into cap rate, since the math is identical across all three. If you are comparing multiple properties at once, a tool that lets you input several deals side by side saves time over running the numbers by hand.
