Churches exempt from property tax?

[Jeffrey J.]

Hello.  So friends of the family are in the ministry and are in the process of buying a commercial business and using it as a church.  I've done some research and have discovered that churches are exempt from paying property taxes as long as the building is used solely for religous activities.  Only issue with the building they are acquiring is that it is a beauty salon and office space on first floor, and legal apartment on the second floor. They intended to use the office space as a church but continue to rent out the beauty salon and apartment to aid in the mortgage payment. So issue this poses in this case is that technically won't they be disqualified from being property tax exempt since they'll be the legal owners of a hair salon and apartment which are for profit business es?
