When driving around neighborhoods look for houses with "For Rent" signs in the front yard. When you find one call the number and ask these 4 simple questions:
1. "I'm calling about the house you have for rent on 123 Maple St. Would you be interested in selling the house?"
If they ans. no , then ask
2. "Do you own any other houses you'd be interestes in selling."
If the ans. is no, then ask
3. Do you know anyone else who has houses that they may be interested in selling?
If the ans. is no, then ask.
4. Are you looking to build your personal portfolio? From time to time, I come across houses in this neighborhood. Would you like me to contact you when I know of a house that becomes available for sale in the area?
