questions about delinquent tax sale properties passed redemption period

[Yanfeng George Li]

Hello!

I bought vacant lands via delinquent tax sale auction in Tennessee. The one year redemption period already passed, now i own these properties (already registered in the county).  I plan to sell these lands, my question is, is selling with QuitClaim deed a good option? I think to convert the title to warranty title would cost thousands dollars and takes a long time, i don't want to go this direction. Also, where/how to find wholesalers? 

Many thanks!

George
