I know that area well. I will also have a rental available on the other side of Folsom right off of Watt Ave. in Rosemont very soon. 3bed / 2bath for possibly 1200 a month. If there is a sign on the particular property you are inquiring about then all you would need to do is contact that person. If no information is available on or at the nearest cross street then I am not sure how you found out about the house being rented in the first place. I don't know if you found it on Craigslist or not BUT you need to be careful of scams. Sometimes homes are listed for a low price on craigslist and they suggest you drive by first to see the area and then request for you to send money oversees or somewhere in Timbuck Too. I do property management for Lyon Real Estate/Downtown Office. If you want any other information or have additional questions don't hesitate to call.
Best of Luck.
