The last two answers are correct about Lis Pendens. It does not mean it is for sale. It is not listed. Usually, when people are behind in their payments the lender will do that. If the sellers wanted to talk to you or others, the property would be listed for sale. Most likely, it is occupied. If you try to go on the property you may be arrested for trespassing or worse, especially if children are living there. People who are scrounging around on the internet for "deals" sometimes get in a lot of trouble by engaging predatory activities with someone or someone's property. I have 2 properties right now that have Lis Pendens filed for more than a year, people are still living there not paying the mortgage, and the bank has not foreclosed yet. In the mean time, they are or were listed, we had written offers that were presented to the banks and th banks have not responded in over 6 months.
Also, properties like this may have a lot of problems that a bank would require to be repaired before closing. So, as stated below, these type of properties are not good to persue until they are bank owned.
Get youself a good agent and let the professional do the work because while you are spending a lot of time looking for what everyone else is that may never come to be, someone else is buying the perfect house with your name on it.
