How do you properly read an inspection report?

@Ross Y.With everything you described in detail regarding your spouse already actively managing your rentals and being able to properly qualify as a RE Professional (included spending more than 750 hrs/yr$ in that role, yes, your Cost Segregation (including any first year bonus depreciation) can offset your other W2 taxable income.

Ford Motor Co. has just announced they will be building a new manufacturing plant approximately 12 miles from this property which is scheduled to come on line in 2025.  

The ADU/duplex idea is tantalizing (they could be 100k cheaper and yield higher rent than a legal technical duplex), but it's always illegal (when not owner occupied and properly licensed) and cities have a really big stick they can shake at you if your neighbors complain.

We will have 2 means of e-gress, proper ceiling height (7ft. 6in), 1,500 sq. ft per unit, etc. for the basement. 

Make sure you'll do proper screening for potential tennant even though you're not completely protected from bad tennants.

My most popular STR is a manufactured home as a cabin in the middle of dozens of acres of forest, which I paid cash for back before things skyrocketed.

Take ownership of your mistake and learn to do the proper due diligence recommended above😊

I work in the electrical industry for a major circuit breaker / panel board manufacture.
