Answer: $0
Step-by-step explanation:
In order for a residence to be classified as a personal residence, one has to have stayed there for more than 10% of the time the property was rented out in one year.
50 days is greater than 10% of 100 days so this is classified as a residential property.
Deductions can therefore be made on rental expenses but only up until the the the amount of the rental income:
= Rental income - Interest expense - Other expenses - Depreciation
= 20,000 - 7,000 - 10,000 - 4,000
= -$1,000
Rental income will therefore be $0.
The $1,000 loss will be carried forward from Depreciation.
