Reading numbers? Anyone ?

[Yuriy Didukh]

Hi guys. I'm not a real estate investor yet, just looking around to learn numbers, have no desire to burn badly on first deal . I was thinking  about house hacking a duplex for a year and renting after .  The duplex that I'm talking about estimated to be around 290000 but I would not pay more than 260000 for it, each unit would rent about 1300 a month and property tax around 5000. Would that be any reasonable or what should I pay for the house to make rental price work. Thanks a lot for any and all comments .
