You should do a TON more research IMHO.
There are multiple types of foreclosures and every property and county will be different.
Lots of buyers so dont expect screaming deals, but rather "deals with risk"
Do you research and you can mitigate that risk to some degree.
I have purchased one foreclosure in the past and would do it again.
The old guy that owned the property went to jail for the remainder of his life and let it go to the bank. He had a son that was not interested int he property or timing of dealing with it and dad had refinanced just a few years before jail (he knew he was going is my best guess).
It was a long drawn out process where old guy was long gone, bank took it back over, bank resold to another bank, and then it came up for foreclosure auction. House went through some deferred upkeep in that 18-20 month time span.
It did not sell for reserve price at auction (typical from my research for online clearing house of bank owned).
Not typical if a county run auction.
You should do everything you can to have eyes on and inside the house before bidding. The more you can know about condition, the better!
If there is a current tenant then pay $ to inspect in advance. If it is vacant then do what you can to legally check it out.
I personally was lucky enough to see the son cleaning out some furniture one day and got to inspect the property so I knew much more about condition than everyone else.
You will need full purchase price on hand once you win. Typically payment in full is due that day or within 48hr depending on auction.
You will need to secure the property immediately upon ownership and be ready for so much more than you ever planned.
Buying a foreclosure is way more leg work up front, but it can pay off.
Fair warning that I know others that have taken a huge bath. Things like rotten subfloors from slow leaking toilets in vacant homes over the past 2 years.
If you are serious, then the very first thing I suggest is attending an auciton where you have no $ and no plan/ability to purchase. Spend the time watching how it all happens. It will help you remove any emotion, have knowledge, and the county people will be happy to answer questions when you tell them you are interested but nit buying currently. Just trying to learn.
