Foreclosure is NOT a good buy for a first home, especially if you will live in it. Usually there can be serious problems with the property, hidden liens and unpaid property taxes etc. There can be also structural damage or significant remodeling required(and most people cannot do it all themselves) Not to mention you usually have to waive all rights, as that is how most banks do it(you take all the risk). Most important, you don't need a real estate salesperson at ALL(of course they insist you do, they have an agenda, to make money, and who can blame them). 99% of they time they add no value to the transaction at all. How do I know that? I know someone who went into the industry just to see what these guys really do, and trust me, aside from a few simple rules(just about anybody can get a real estate license, aside from felons, after they take a simple class and pass a fairly easy test,) and making the whole process seem complicated to the customers, there is NO value whatsoever of a real estate salesperson or broker, except for the higher price you pay for the house since commissions are in the price of the house. You can do comparable sales yourself online, or have an appraiser show you comparables if you are too lazy or don't know how to find the sales.
Foreclosures are best bought with cash, loan process will be quite complicates in this economic cycle for these types of properties(since really nobody knows what they are worth anyways). You can probably forget about zero down. And if you don't have anything to put down why are you even buying a house to begin with???? Hopefully you are not hoping it will go UP in value any time soon, which it will definitely not. You will be competing with literally thousands of other sellers trying to get out and with bank owned properties. Banks can liquidate at firesale prices and even take a huge loss if they have to just to sell, you likely will not have that luxury. My advice. Stay out of the real estate market if you don't know anything about it. Anybody that tells you it's a great deal and you need to act fast most certainly has something to gain from the transaction and does not have your best interest in mind. It's likely a bad deal at that point.
If you really, really want a foreclosure, which I do not recommend, wait another 5 years(real estate prices will be falling still for a long long time, you will see). You will be able to buy a decent house for $20K, when banks throw in the towel on their REO's (that's Real Estate Owned). Just don't think you will have cheap taxes, because counties need their "milk cows" to pay for all their inefficient services they offer to the public. Taxes will likely be 20% of the house price at that point. Keep renting and be happy. Ask for a discount from the landlord, or tell them you will move. They will likely lower the rent instead of having an empty apartment or taking the risk of having a questionable new tennant. These are times for renting not for buying, and that is an honest truth. Good luck.
