Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Would you recommend we keep the house or sell it?  

Hey @John FriendasI have purchased 4 of my Co-Living (rent by room) properties with DSCR, 1 of them within the last few months.Not that I necessarily recommend this, but there are short-term-rental DSCR products.

Also, any recommended PM's in Calgary? 

Bigger Pockets is a great place to find a real estate tax accountant.A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a accountant willing to work with you throughout the year.

It's hard to give any recommendations without any specific questions/real numbers.

Does this structure make sense for investors, or would you recommend different terms to make it more appealing?

I recommend that you look at Notice of Defaults, Vacants, Tax Liens or Probate. 

Is it still not recommended to invest in this negative cash flow property. 

Here's some online software options that you commonly see recommended on BiggerPockets.
