3 deals down the drain

Ok, so I posted a photo of 2 contracts recently valued at $4k which were supposed to close. Well the first one I find out has 2 mortgages on it and the gentlemans wife on the deed that passed away a while ago. When originally I was told the property was owned free in clear. This deal is not completely lost because the homeowner is looking into clearing up this matters. There really are no mortgages its just the companies that held them never updated there files. 2nd deal the house was freaking perfect to wholesale but area was aparently too rough for anyone to have a serious interest. That deal was my fault because I was unfamiliar with the area and should of let it go to begin with. Needless to say homeowners were upset when we cancelled the contract and returned the keys. 3rd deal was supposed to close this Monday for a profit of $3k. Homwowner was the biggest pain to deal with!! Then last minute he decides he doesn't want to sell and has life issues to deal with and that he will call me when he needs me. (SORRY MAN I DON'T WAIT ON ANYONE! I DON'T NEED YOU, YOU NEED ME is what I say) This guy was a pain all the way from begining to end. Rather deal with truely motivated people then tire kickers. His loss of $27k cash in his pocket. Tough sh@t for him I guess? I know I said earlier I posted a photo of 2 contracts. 3rd one I didn't post. But combined profit total for all 3 whould of been $6k total. I am just posting this to show you people that all deals don't always work out but you gotta move on to the next and not get discouraged
