Take out your calculator...multiply 27K by 1.16 over and over (to represent  your 16% annual cash return compounded)...and see how many years it takes to "get wealthy" by whatever your definition is. 

But the one that I was told is the easiest and quickest way to estimate is to multiply the square footage by $20 or $25.

Also you need to multiply that list of 150 by 10.

The gross rent multiplier is $105.

That would come out to be about $10,299.17 per month. 50% of the monthly NOI is $7575, subtract the loan and you get -$2724.17.The GRM (gross rent multiplier) is 8.

I understand the process of finding ARV and then multiplying that amount by .70 and subtracting repairs cost to determine the amount an end buyer will pay for the property.

We've done it a lot & still do & have been told to "go forth & multiply" many times, in fact one nasty owner came back to us several months later & we got it for our offer, because all his <mkt rent tenants bailed pending a sale. 

I know you have to take the property as a whole and all look at all numbers, including location, NOI, Cap rates, future value speculation, Gross rent multiplier, etc, but is there 1 main item that you're looking for that helps you decide on whether to pull the trigger and purchase?

Take 2019 payroll divide by 12 multiply by 2.5 is max.

Take that PPSQFT and multiply it by your square feet.
