I wholesale houses to a lot of investors in Columbus and everyone has their own formulas and criteria that they target.

@Marcel Pean That formula is a base line. 

If you starting out , I would recommend to go with single family or duplex. 1% formula is hard in GTA and surrounding areas but there are multiple ways to make money in real estate.

What hurts Investors that use this formula is it does not account for Holding Costs, Backend Selling Costs, etc.I use the following formula to determine my Maximum Allowable Offer (MAO).

Are there some math formulas that help?

There is no one formula to start in real estate.

They use a formula to figure out my monthly premium, based on the properties you own as of the first of the month.

If you think back to when we were kids and learned how to find the mean average of something, that formula will look familiar to you. :) 5 grapes plus 7 grapes divided by 4 children equals an average of 3 grapes per child.
