Remember that Bank Owned properties are sold as is. Until you have a home inspection you really do not know exactly all work involved. Now it may look like plumbing, but the inspector will likely find other issues as well. My suggestion is to not get in over your head. Make sure you have enough funds for a few months of extra mortgage payments as well as money to fix up the house.
If this property has been on the market for over 30 days and there are no other offers on the property then you may be in a good situation to get a good deal on the home wherein you won't be "at the top of your range."
My suggestion is if you desire to see the property again and want to write up an offer, to call the agent that showed you the home. Whether you build a relationship with the agent who showed you the home, or with another, it is important that you work with an with an agent who can guide you through the purchasing of bank owned homes, so that they can inform you of all it entails from the bank addendums to the inspections.
Again, do not over stretch yourself, if you can't get this house, another one will come along. In addition, some bank owned homes require you to be pre approved through their lender, prior to making an offer. You do not have to use their lender, but they want to make sure you are a viable candidate.
