Owner wants to sell house owes back taxes

[Jamane Y.]

I was contacted by an owner of a house in poor condition. She owes about $11,000 in back taxes on the property. The tax assessed value of the property is $58,364. She told me it is 3 bedroom 1 bath. 988 sq ft. The houses of both sides of the this house are assessed at $116,655  1,788 sq ft. and $114,466 2,120 sq ft. She said the house is in poor repair, needs new roof, plumbing, electrical, maybe more. I haven't seen the inside yet. Need ideas about what to do about this. I want to flip if possible. I also know that the taxes will have to be paid. So I assume the tax amount gets figured into the overall expenses for the house. I know I hate assuming. Thank you in advance for any assistance.
