Investors & landlords

THANK YOU for your quick response.  I understand your answer.  In reply to your request for detail, the house in question is a large single family home and in the long term shall remain so.  I finished enough of the house to rent out most of the first floor while the upstairs was sectioned off.  When I finish the second floor this year it will still be a single family home only with more square footage.  I plan to put the house on the market as soon as it is ready. 

I have another question.  Should I post this separately?  My husband and I file Married Filing Separately because he wants nothing whatsoever to do with my rental properties including tax filing.  I also have a part time job.  I spent much of my year dealing (actively participating) with a different property that is a 2 family rental and lost about $25,000.  Yes, $25,000.  It doesn't  make a difference if I check off QBI or not, it doesn't let me take the loss other than a small portion of the loss off setting a small profit in 2 other buildings.  I spent >750 hours dealing with this property but not 750 hours each with all 4 properties.  Even though I Actively Participate in all of them, I don't Materially Participate in all 4 separately.  Is there an option to have this loss qualify for a partial refund perhaps through a "Safe Harbor"?  I went to an accountant to ask questions but she wasn't that familiar with the new Safe Harbors.  Thank you for your time.
