Touring properties with an agent was definitely helpful for me.

I read that there were "guided tours" organized through old buildings and there were lots of foreign investors. 

He said he had like 10 tours scheduled.

In my view, that should include a visit to the area and tour with the provider. 

This requires you to recognize what one of those deals looks like... which requires you to be able to properly estimate the rehab on a property... what the roof, the flooring, the holes in the walls, the paint,  the old AC, etc, etc is going to cost so you can know if you even want to put the property under contract.Worst case you can bring a trusted buyer along with you to tour the property with your seller.  

I would prefer a facetime video during the tour if possible.

Listen to podcast, read books, attend investor tours and learn from experienced investors.  

A majority of buildings I'm touring with clients these days contain tenant(s) in some state of delinquency, so become comfortable with inheriting a possible headache.

My question is:  do we list it now for rent available as of 5/1 and if so how do we deal with the people that want to come for a tour (understandable)? 

Get the ARV's, tour the house and create a repair estimate and determine if its a deal using those numbers first.
