what happens when the lights turn on?

[Alex Yost]

As a new investor, there are a lot of unknowns.  Because many of the homes I am looking at do not have water or electricity, I wonder what I will find when the power and plumbing get turned on.  If you have tips or ideas on how to know what to expect, I would be grateful for your insights. One big one might be how to get an idea whether the HVAC works? Thanks in advance
