FHA loan on triplex, how to leverage?

[Justen Ashcraft]

Just over a year ago I purchased a triplex and fixed up and moved into the lower unit. After a year, I moved back in with my wife at her house. She owned it before we had met. I have an FHA mortgage, and would like to know if/how I can use this property as leverage against another. Is it possible? I understand a HELOC is out of the question, because its not my primary. Are there any other ways to leverage an investment property? I haven't gotten a new appraisal as of yet, and won't if its not worth it. Thanks.
