There is also HOA of $353/month that covers ext. insurance, water, sewer, ext. maintenance including snow removal, trash, and some shared amenities like pool and BBQ area.  

I felt like I was in a snow globe the whole time.

I invest mainly in Florida so getting into the PA market is a little scary wondering about snow storms and insurance.

How do you handle snow removal for your multi-unit properties?

But because of the property being a duplex, I would assume that I would be paying for upkeep of lawn and snow removal. maybe $1200 annual?

Your insurance should be a little lower but it doesn't appear you've accounted for any water, sewer, trash, common electric, snow removal, lawn, etc...

I am in my 20's now and hope to have a cash flowing property before 30.

If you live in the north, however, i think it's important to observe what happens during the snow melt.

The expenses include things like taxes, Insurance, gas, water, electric, sewage, trash, lawn, snow removal, management (if not self managed), capex buget, a portion of your legal fees, CPA, marketing, etc.
