Use local licensed professionals for starters. Your profile says your a buyer, so a great local agent should help. If you are a renter, NEVER send money overseas hoping for keys in return mail. This is an ongoing scam that continues to victimize people.
Scammed: If it sound too good to be true. If you have to pay money up front. If you have to send money in return for promise of keys. If the person you're dealing with claims to be the owner but is out of town or out of the country.
Scanned: We all are. With electronics and technology today, we're being constantly monitored and scanned.
