It sounds like your CPA is confusing 162 with being a qualified real estate professional under 469 - two very seperate and distinct tests.The one rental area where the QBI is quickly lost is triple net lease, but even then for a landlord in the business of doing triple net leases, they could qualify for 162. 

Put scented driersheets in all compartments and rooms.

@Joshua T.I believe he is making a distinction between "private mortgage insurance" and "mortgage insurance." 

No such thing anymore. yeah, technically, some VA loans are assumable and yeah, technically, some legitimate successor's in interest may be eligible for an assumption however under all scenarios, you must qualify as if you were taking out a new loan (There are very clear distinct extraordinary exceptions).

Maybe you just mean that for example purpose but I just wanted to make the the distinction that cash flow is not equal to rent - mortgage.

Now that you have the scent of what you want in life, follow the breadcrumbs.

I know that's a long-winded explanation, but the distinction is important as you look for a home to house hack and determine what will fit your criteria.To answer you questions specifically:Yes, house hacking deals exist where no renovation is required.

My CC bill is due on the 23rd...... my water and garbage is due on the 15th......... my cell is due the 21st....my HOA on the 8th...... my cable the 25th......As long as its every 30 days....written in the lease....... distinct late dates and fees...... who gives a F.......Not all bills are due on the 1st......One "good" inherited tenant....don't overthink it..... its not that big of a deal.

Want to make sure that you make the distinction here. 

@Brian Ellis there is an important distinction here that no one has mentioned (unless I missed it).
