Lot sale/TAX SALE nightmare

[Isaac Antoine]

Happy New Year fellow investors, In 2015 I purchased a distressed multifamily (Cash) from an owner who owed taxes on the property. He liked my initiative & zeal, and he gave me a lot of land with the purchase of the multifamily. Fast forward to now, I'm currently under contract to sell the lot of land & upon researching the title, there is a tax sale prior to me purchasing the home that was never paid. I found the tax buyer from 2008 , which paid $238 for it & he has no interest in receiving a $1,000 check to sign his rights from the land. This is a potential deal breaker since the buyer is not looking to wait until I settle this issue which I never knew of. What should I do? Regards, Isaac "Ike" A
