multi famiy underwriting techniques

[Robby Sanchez]

Hey everyone, me again, I am practicing underwriting MF deals and came up with a few questions (I am sure there will be more). 

-when figuring rules of thumb regarding payroll cost per employee/position or things like repairs and maintenance cost, contract services, etc. per door in a specific market do yall suggest contacting a property manager to find out these numbers or actually using google or job listings etc. i thought about using chat GPT as well. any thoughts on this? I realize that these numbers change depending on size of the property, position type etc. as well as every market is different and fluctuates. just trying to get some general advice on this. TIA
