Need help Analyzing a duplex

[Chris Fatur]

Buying my third property in Sacramento where I invest, I'm purchasing a duplex and kinda just got lucky with my first two deals, what's the most important numbers to pay attention to when Analyzing a deal, my main thing i need is a general percentage for expense aside from mortgage and property management... vacancy and maintenance ect. Thanks for the help!  Also is there anyone out there that thinks Sacramento is a good or bad market ?

Generally, the most important number is the income or rents. It's important that rents are accurate. using Zillow, RentCast, or other rental sites is a good start. Talk to local agents and property managers about how much they think they can get for rent and what the demand is like on that block. Usually taxes you can be certain, after that, the expenses and vacancy are going to be important to get right, but these are unknowns.
