I have sold a few short sales but I have lost a few potential buyers also who initially wanted to buy a short sale.
The major inconvenience is not really knowing if the lender will accept your offer to buy. I counsel all the buyers that there will be days and possibly weeks before you receive any word from the lender's negotiator. If you really want to buy a short sale, start saving alot of patience, because you will need it. There recently have been changes to the way short sales are processed through various lenders so the time frame may be less, I haven't seen that yet.
Another inconvenience is that the seller may not be able to repair any items that are found by your home inspector or items needing to be corrected due to your lien search.
These are just a few items that may inconvenience you. do not let that deter you if the home you want to purchase is a short sale. Stock up on the patience and once you get the go ahead from the investor(s) that your offer has been accepted, it usually will flow like a normal home purchase.
Wish you well. Call or text me if you would like any further details.
