I can not name any reasons which are worth the extra effort of investing there compared to sticking to a specific USA market.

Are there any specific clauses I should include in a room-by-room lease for a shared living space?

Worth a discussion if you want to send me a DM I can connect you with my team’s DSCR specialist.  

And your team would be local.    11.  

Are there specific states or locations you’re looking for?

Investing in AZ, NV, ID, where you have family or friends that is a day away and you can start to build a network and team to help manage a property.  

There are a lot of good meetups for real estate investors in the area that would be good to grow your network and learn from others that are and have been in your shoes as a new investor, message me and I can share on some specific monthly meetups.Also sharing some multifamily data, this is Boston proper so it has an interesting trend compared to the rest of Massachusetts.

I’ve never had this specific issue but mistakes like this are pretty common. 

The committees have never said they'll require a specific form of evidence to show that you've rented the place for at least a couple of nights.

I will preface this with the fact that I have a legal background, specifically with estate planning and asset protection.
