Seems like you tried to cram too much into the subject box. You could have added details in the text box below it. Are you saying you tried to purchases a house and lost out to another buyer, but the seller kept your $5000 earnest money deposit? And you want to know if you should issue a 1099 to that seller who kept your deposit? Why do you think you need to do that? 1099's are issued by a business or a financial institution. And not sure why the end of your post says "SSI." Why did you mention SSI? What are you trying to do?
