Is this multi-family worth buying?

Price $775K, Side by Side, each side 3br/2bth 1650 sq feet
Build 1996 - in this area, 1996 house is almost like new, 90% are > 30 yr
Rental income $6800m (3300/3500 month to month)
Tax: $15900 annually, Good schools
1.5 mile to train station, 40min to NYC

Pros:
- Still robust local rental mkt due to high purchase cost
- Positive Cash Flow desptie high tax (R.E investor\'s dream)
- Pretty new construction around here

Cons:
- On a relatively busy road
- Housing still in a downtrend in NY surburbs
- High tax could negatively affects future apprecation

Appreciate XDJM\'s valuable opinion in advance!
