Debra, How were you able to contact the owner?
Real estate presented on Trulia is marketed by real estate professionals.
It appears you attempted to circumvent the protections provided to buyers when they operate within the professional community.
You in essence, by contacting the owner directly, are attempting to 'rip off' someone else.
Hmmm, maybe you should send them your $800 dollars. :)
Come on, tell us what's really going on. Did I miss something?
