Investors & landlords

This might be a strange question but: 

 

My husband got a promotion within his company.  His job base is 50 miles further from the house then his old job base, but: 

 

1) He works from home

2) We moved to a house that is further away 

The reason we moved, was because in the house we sold we shared an office.  When we bought the house, he didn't work from home, so us sharing an office for our free time wasn't an issue.  With him working from home permanently with the new job, and me working at home occasionally, we believed it would be better for him to have his own dedicated office space so we wouldn't interfere with each others work.  We moved about 10 minutes further away from his new job base than our old house, into a house with an additional room that would serve as his office, but a commute wasn't the work related reason why we moved.  Will we still qualify for a partial exclusion?
