You may get the property at a discounted price. This is probably the main factor that attracts most of the investor or bidders.
You may not have access to the property for inspection before the auction.
If the property is occupied, you may have difficulty to evicted current occupant.
As we do not have chance to inspect the interior of the property, sometimes the repairs can be numerous. So, please bear in mind of this factor and take the repair cost into consideration when deciding the final bidding price.
Happy Bidding !!
