Adam the only one that will know for sure is the listings agents themselves, they may not be seeing your posts on all the properties. The link you are pressing does not go directly to them. You will be better off to do one of two things, click on the link for the property, then click on the link for the listing agents website and email them dorect or even call them. If you do not want to acall or contact all of these listings agents direct, you shoul dget a buyer broker who can assist you in finding an owener financed property. I must warn you there are not many, most sellers already have a loan so they cant give a loan and those who owe nothing are going to want 20% down and good credit. but dont give up, there may be one, you just need to contact each agent individually. good luck with yoru search.
