?writing off expense (rent) for staying in own STR

[Sheena Drake]

If you purchase a STR and inhabit it to do repairs, are you able to write off the "rent" that would otherwise have been collected from guests? I know as a vacation home you are expected to dwell within the resident for at least 14 days of the year, but other stays that might be needed for upkeep might be write off costs? This may have been answered in one of my books but the thought just popped into my head while working. Appreciate all you smart people out there!
