Ok so im selling my mom's house and have been in contract with a a realtor for 2 months. I suffer from anxiety and one day before closing they found that my brother owed 20,000 in child support and a lein was on the house. With it being his homestead,the attorney finally got it off. Well when I found out about the child support lein,I became nervous and called a place that buys houses fast,they came out and took pics and said they would buy it and to go back to their office so we could talk,so I did. I told these people several times I was in contract with someone else and they said that what I am signing is not a contract just an offer and if the other place couldn't find a soultion to the child support thing,they would buy and I had till the 8 of march 2016,yes they put the wrong year,to decide,not even an hour I called them and told them that I would not need their service,that my realtor came up with a solution,they called me two days later,at 8pm at night,sounded drunk and said I couldn't back out,that I signed a contract,well I pulled the paper that I signed out and at the top it saids real estate purchase contract,he had that covered when I was in his office. So I read it and the date he put on there was the closing date and it had 2016 not 2018. They call me every other day,at 8 or 9,they sound drunk and they are rude saying they will cloud the title,I had to call the cops and report them because they were parking across the street,I do have a case number. I looked on the county clerk records and they did put a cloud on the title,I'm supposed to close Tuesday and my question is ,can I get that off? Will they still by my house with that on there? What do I do? I now read everything before I sign and I don't trust anyone. I told these people that I am only selling my house to get an updated house for my disabled brother and they said they didn't care. Help
