Wholesaler and title issues

[NA NA]

Hi guys have a couple of qns abt wholesalers

Heard there r investors acquiring hses from wholesalers for buy and hold but the problem is most wholesalers have hses with no clear title and purchasing them is taking over the liens 

Are there ways to acquiring from them and have clear title? Do investor have to use a title company to do double closing or generally any title company would do

Any wholesalers with hses comes with clear title?
