Foreclosure auctions can be great opportunities for acquiring properties below market; but the well educated and well studied investors devote a great deal of time into being able to identify those prime opportunities, and they all show up to compete at the auction. Even then, you may get a "good deal" but it is still representative of fair market value considering that it is a distress sale, and with any distress sale comes some red tape and some level of risk.
In today's market, there are "deals-a-plenty" with less risk involved. I do not recommend that many people purchase at foreclosure auctions.
Despite that, should you decide you wish to, I recommend that you hire consultants to help you, and consult the trustee to learn the required terms of sale. Your team should include a real estate agent who is knowledgeable in the area and with auctions and a real estate attorney who can help you understand the risks involved in these types of sales, including any possible right of redemption the current homeowner might have after the sale. (Yes, that's right, in some cases, the person that lost the home to foreclosure may be able to get the property back - it's called a right of redemption - and the laws vary from state to state.) The real estate agent can assist you with determining an appropropriate value, and help you plan for whatever disposition or long term hold goals you may have (meaning evaluate opportunities to "fix and flip" and/or hold the property as a rental). All costs to conduct due diligence (inspections, appraisals, price opinions, title searches, etc.) are your responsibility.
In the next post, we'll talk about what I call "retail auctions", where privately hired auctioneers are hired to conduct auctions on site or in ballrooms or convention centers, or perhaps an alternative site.
