Completed rental agreement with them, wired almost $3000. Hadn't heard so I called them back. All phone numbers have been disconnected. My last contact with them was 7/9/2009.
Nationwide Capital Asset Corp is apparently the "parent" scam company.
My real estate contact was Alex Wong.

The "president" of the Nationwide Capital Asset Corp is Konstantino Kouris

DO NOT DO ANY BUSINESS WITH THEM AT ALL.
Travel Link Unlimited is NOT licensed in NV to perform real estate rentals. As of right now I am not sure about the parent company.
Please use VRBO.com next time. Deal directly with property owners.
