are you merely in the stage of "planning" to buy or already sucessfully bidded?

well, if u r still in the early stage of "researching", do proper land search, site visiting to ensure condition of the Property as well as "to know" the tenants.

if u were a successful bidder, the auction process will be simpler if the house comes with a title (same still under master title), as every important documents will be safely placed in the possession of Land office or Court, lawyers just need to do the necessary at the end to get Bank to release payment, not so hassle transaction.

Just monitor closely the transaction, follow up promptly with ur lawyer. good luck!
