I actually don't have a problem with this....so long as it's only random 5 day periods over the course of a year.
Back in the real estate boom of 2001 to 2005, it was common to see homes in rural track home subdivisions, convert their garages to living areas...but leaving the facade of the garage door, though no longer operable.
The garage would have a side entrance.
Many homeowners use this 'rental' income, usually rented to family or work buddies...to pay for such things as automobiles, or utilities.
The tip off? More than 3 cars on the premises.
