Oh please, I bet next you're going to lecture us on how he needs to "take control of his personal finances before investing"I think it's obvious what this guy needs next - a hard money loan. 

Now to PROVE that a seller knowingly knew a material fact and did not disclose it or hid something is a very high bar to reach in court.In the purchase and sale there is generally a section that absolves the brokers of any liability and that it is upon the buyer to investigate things and use the proper experts accordingly.Your best bet at this point might be to pay  a few hundred to a commercial litigation attorney  not to do litigation, as that is extremely expensive, but have them review your case.

The best bet is to contact whoever in the Health Dept that issued the notice, filed the lien, whatever the case may be, and get a punch list of exactly what they want to be done in order to satisfy their needs.  9 out of 10 times, if you are on the up and up, and are a responsible and proactive individual, that is all that they are looking for.  

Watch what this sells for - I'd bet it'll be north of $425k and all cash.2.

@Tim Mcbee I agree, that's the best bet. 

Your best bet is going after the drunk drivers insurance.

I bet there are tons of properties right in your neighborhood.

I bet if you step to the bat and take some swings, after two or three attempts you can really get some good experience under your belt and really start to crush it.

And you can bet that if that changes, ABB will start blocking the links.ABB blocks ANYTHING reminiscent of Facebook.

I feel confident in my ability to estimate, but I'm not sure that I'd bet $10,000 on it!
