@Scott Ray the way you have structured the investment eliminates double taxation situation, but as as a Canadian resident you are required to report the income here in Canada.

Over 1 month with 124 Zillow potential tenant contacts, the property manager report showed no leads from Zillow and couldn't find tenants.

Rental income would be reported on Schedule E, and these write-offs could offset other income if you qualify as a real estate professional.

Issue a 1099-INT for interest paid over $10 annually, and ensure family members report the income.

I'll post back here when there's something to report but it may be a while.
