First time investors need help analyzing and deal

[Ramona Beyer]

Hello everyone, 

We have taken a HELOC for buying our first investment property, and I would like to know is this duplex a good deal to buy? Asking price is $32500

Taxes are $3900, both units are 3 bedrooms 1 bath, and are rented for $600/$675, one tenant has been there 6 years, the other 6 months.

First question : is this a good deal?

Second question? Since this house will be pain in full, with HELOC what the best way to pay Heloc/should we refinance it later?

Thank you so much, 

Ramona
