Apartment building in Pembrooke NH

[Tawa W.]

I am evaluating this property in Pembrooke NH: http://www.trulia.com/property/3227970400-116-122-...

It would be very helpful to get some feedback on the numbers and area.

The property has 5 apartment units and 3 commercial units. They are fully rented (month to month) and gross ~$64000, with $17,000-$20,000 in annual expenses, before loan payments and management fees. 

I am estimating that with loan payments and management fees, this would net $10,000 to $18,000 annually, depending on vacancy and management fees. This doesn't yet take into account repairs, etc.

I am new here and wondering if there is something significant I am missing in terms of these rough calculations. Roughly how much of this would need to be set aside for repairs? By my estimate, this would be 11-20% cash on cash return. Are these reasonable returns for this type of investment? 

Finally, any feedback around the Pembrooke NH? 

Thanks,

Tawa
