You will have to become active and join a firm (affiliate) where you'll have oversight, and if you want keys to the kingdom so to speak, you'll have to subscribe to your NAR MLS, perhaps your commercial board, and all the memberships your firm requires. 

If not you can go to the office and search OR order a title report on it from a source like protitleusa.com (note not affiliated with them, we do use them to order our reports)

Affiliates with NARPM (National Association of Residential Property Managers) see if there is a local chapter in your area3.
