Can losses from property w/ net loss be applied to other property

[Bryant Fong]

Hypothetical scenario.

Property has 10k in income, but 15k in expenses (5k depreciation, 5k property tax, 5k mortgage interest).  Other properties DO have net income.

What happens?

a) Losses are deducted from all combined properties together?

b) Carryforward losses to next year?

c) Losses beyond "zero" are not deductible?

Thanks!
