There are an array of books, videos, and groups to learn from out there so be sure to use all of them to your advantage.  

That said, I always stage BUT like many other comments around flipping, your point to the market is relevant. 

Document the tour with photos and videos for detailed analysis later.

I have a very helpful video on my YT channel (just lookup ClosedByMo) for NYC househackers - you'll enjoy it! 

Do they have relevant credentials, like Certified Investor Agent Specialist (CIAS)?

The other question is equally relevant - does it make economic sense for you to do the work yourself?

I've been watching a lot of BP videos and trying to educate myself on real estate business.

The guest typically goes to the curb ("public area") during the day to smoke, but I do now have photos/videos of them smoking definitively on the property (on the premises near the front door - not the "public" area near the street). 

They can help you understand the legal and tax implications of investing in US properties and ensure that you comply with all relevant regulations.Hope it helps!

Reading, watching youtube videos etc. is great, however nothing beats meeting and being around active investors.
