Multi-Family Purchase Analysis

[Kris Miller]

I am new to BiggerPockets but looking for a second or third opinion on a multi-family purchase analysis in Fort Wayne, Indiana area.  I am looking at a 15-unit property.  I have run it through the BP Calculator using expenses provided by seller and some of my own assumptions.  Current monthly income is $10,225, my assumed operating expenses (excluding loan pmts) are $4,996.  Is there a quick way to calculate what I should offer or ultimately pay?  The property is off-market and this was the result of a letter so the owner is not extremely motivated to sell.
