Homeowner died, no heirs. Is this probate situation? What next?

[William Anthony McQueen]

I found a diamond in the rough in NC. Great home. Nice neighborhood. The owner passed last yr at 94 yrs old. Has 2 living brothers but no named heirs on the property. Taxes are delinquent for past 4 yrs. How do I go about this? Do I reach out to her elderly survivors? Do I go to probate court? Have NO clue what to do but I don’t want to walk away without at least asking the question.
