There is so many ways it can go wrong and being a greater negative for parties involved. 

You don't want to start playing sides here and getting involved in these kinds of debates.

My take is that a Host should be personally involved as much as possible.

Additionally, consider operational costs like cleaning, staffing, and marketing, as they can quickly add up.For management, outsourcing to a professional property manager or leveraging tech platforms for bookings and operations could streamline things, especially if you plan to scale.

You are correct, however I was clarifying if the ask involved trying to figure out a persons’ citizenship like asking for a the person’s green card in addition to or in place of. 

While I haven't done new construction as an investor, I've been involved with them on the design and construction side. $15-$20,000 seems like a very small profit on a $500,000 house.

Also, our properties are commercial so it's not like I'd need to go to a duplex and sweep and clean the place.IMHO my CPA is not conservative at all. 

Leverage magnifies return. 3) The effort involved in adding an ADU is comparable or larger than a rehab associated with a BRRRR.

I feel like it's a space where great operators can really clean up, since the bar is set really low, in my experience at least.

STR management is 20-25% (I would recommend self managing or getting a VA), since income is higher you could probably get away with 5% for maintenance / cap ex but remember you need to cover utilities and cleaning for these units which drives up costs.
