Newbie Numbers Analysis. Expenses Too High?

[Ray Tapay]

Newbie here trying to learn how to calculate numbers. I just picked a property on Redfin for practice called the insurance company to get a quote and asked around for water and sewer prices. However, my expenses based on the expenses I am seriously overshooting the 50% test ($1450 for 50% test vs $2075 estimated expenses). Am I missing something here or these expense numbers are high? Or maybe the figures are over estimates? This doesn't even include garbage, lawn care and snow removal.
