How to value a multi-unit property in detail

[Andrew Machado]

Exactly how do I get the figures to calculate NOI, cashflow etc. I understand the formulas but where do I get the variables? How can I find out exactly what the rents are for each unit and what the expenses are? Also, once I get my hands on the information how could I determine if it is valid or not (if the seller is inflating the rents or not being honest about the expenses etc.)?

I'm just starting out and I've contacted a few realtors so that I can look at a few properties. I want to get comfortable with analyzing and valuing properties before I move on to the next step of my investing plan.
