Please check the address and write back. That address is not listed for sale in the MLS.
Where did you find the address? It's possible it could be a foreclosure, however.
Any realtor, real estate agent, or broker can show you any property for sale. Just do NOT use the listing agent for your agent. Their first priority is the seller and getting them a high price. You come in second. Just as you would not use the coach of an opposing team to win a game you should not use the realtor of the seller.
