Need help with valuing multiunit property !!!

[Brian Warren]

I had a deal in front of me and need help determining if this is a good value.... It is a low cost low income building. I have a break down of all the numbers but I’ll just throw out the basics Gross rent is $234,000 on an upward trend producing closer to $22,000 a month last 4 months, seller has been clearly cleaning things up a little before selling The balance sheet that they gave me shows $98,000 NOI but they do not have property taxes listed and makes me wonder what else that they left out.. But either way that should still keep the NOI above $90,000 The asking price is $800,000 Looking for advise from some experienced investors Thank you
