Just wanted to chime in from a tax perspective, something to keep in mind and plan to have some discussions with your CPA:Using the property for personal use during the year will prevent you from recognizing some expenses on your property.

I am hoping to find a single family home that I can "BRSTRHHRR" (buy, reno, Short term rent|House Hack, refinance, repeat) by creating a separate living space in a single family home that can be STRed (this is due to local restrictions in my town that prevent STR in multifamily properties). 

If accurate then the SEC rules are designed to prevent unsophisticated investors from getting into this exact situation.

Tight tenant screening is always a key factor in preventing costly evictions. 

All rooms get punchcode locks, no key locks anywhere on site so members don't have access to lose keys or prevent anyone access. 

There may be an abundance of STR-preventing ordinances (or a lack of legit STR managers) in an area that would make following your recommendation difficult.

I think it's about preventing abuse so you don't lose thousands. 

I guarantee it would be a big issue and there would be talk of how things can be corrected or prevented from such a rate of such. 

If you understood the technology, you'd understand that there are ways to prevent people, or at least catch them catch them, when trying to evade paying taxes. 

This "analysis paralysis" can prevent them from acting on opportunities out of fear of making the wrong decision.I’ve experienced this journey myself.
