So just multiply that Cash Flow number by 5 and you get a CF per year of $20k. 

There are too many problems that can arise and they are multiplied greatly when you have multiple units.

Then multiply that by how many sqft the property has and that should get you a close enough estimate.

I’m ready to purchase my next investment property in the ALBANY NY market and Most of what I’m seeing are a lot of $200k 2 families with decent COC, but not much upside on rents or appreciation.How do you view those sort of deals, with good COC but lacking some of the other multipliers for downstream revenue?

For my max offer formula: You will see this same formula used across BiggerPockets articles, Podcasts, etc. with different percentages multiplied against the ARV, usually 70% - 75%.

@Greg HillsEach line item would have its own multiplier for the price per foot.

. $600/mo x 12 = $7,200/yr --> you're collecting $1900 a year more - multiplied by 10 units - and that's a substantial amount!

When most people are hoping that $80k house in the midwest will return $200 a month in cash flow, I just multiply everything by 10, and hope that the $800k house in DC will return $2000 a month in cash flow. 

If this property will really have an ARV of $470k I would definitely purchase the property because the big money is in the ARV when it is higher that the purchase price and your rehab costs are not high and the profit is in appreciation due to the rise in housing prices and due to increased annual rents when the Gross Multiplier applies.This is how it looks with an ARV of $470k

From a systematizes point of view The majority of legit wholesaling companies out there are not operating based on investors' mood or capital, they are operating on set formulas as per what the market is allowing them to have. ( this is an inside view from the other side)  They operate with 0.70 to 0.80 minus repair multiplier (on flips) Regardless of deals sometimes they are off and sometimes they are right, It has to be that way in order to create a streamlined process and create a flow of properties.
