Which version of the request for single-family housing loan guarantee form is the newest?

The newest version of the request for single-family housing loan guarantee form is 6-15. This designation indicates that it was released in June of 2015, making it more recent than the previous versions listed. Understanding the versioning helps identify updates in policies or procedures that may have been introduced in the latest iteration.

In this context, 5-15 refers to May 2015, which is older than 6-15. Likewise, 6-12 indicates June 2012, making it significantly outdated by comparison. Version 7-15, while seeming newer due to the "7" designation, actually does not exist in the context of the request for single-family housing loan guarantee forms; the series did not progress to that number. Thus, 6-15 stands as the correct answer due to its recent release date and relevance to current guidelines.
