Looking for advice on an analysis of a triplex in Minnesota

[Account Closed]

Hello fellow BP members.  My name is Sean Dawson, I am a biggerpockets member and have been analyzing multifamily deals in the outer areas of the Twin Cities using the biggerpockets calculators and ran across a triplex that looked promising.  I was hoping to get some feedback on my numbers since I don't live in that area and don't know the market up there.   Is there something I'm missing?  This is one of the only deals I've seen where cashflow isn't negative. 

1968 triplex with 3 car garage on the market for 71 days.

Purchase price: $289,900

Estimated cost of repairs:  $5000

ARV: $335,000 (this is best guess with what comps I was able to dig up)

Closing costs: $2500

Down pmt: 25% ($72,475)

Loan amt: $217,425 amortized over 39 years @ 5% interest

Utilities are paid by tenants so I would only have to worry about trash ($84/mo), insurance ($167/mo).

Maintanance and repairs: $132.10

CapEx: $264.20

Vacancy: $132.10

Property taxes: $279.67

Rental income: $2642.00

Cash flow: $415.75

Cash on cash ROI: $6.24%

I have not walked the property so I can't be certain what the HVAC or roof look like.  The purchase price is also the asking price, which means I could potentially ask less since it's been on the market so long.

Any advice or input would be greatly appreciated in my quest for knowledge and education.  Thank you in advance.
