commercial/residential property

[Robert Car]

Hi all.  I am looking at a property in New York state.  Several years ago it shows it was purchased for a certain amount of money.  Then a Federal Credit Union purchased it for $1.  Now it is showing it is for sale for over $200,000.  which is about 15 times the purchase several years ago.  It shows a realtor/broker to contact, who I am sure is going to want $200000 for the property.  Does one only communicate with the advertised broker or does one contact the financial institution directly?  Looking for pointers. This would be a first here.  Thanks!
