One aspect of doing your due diligence is inspecting the property. However, most foreclosed properties out there will have no electricity because it has been disconnected due to non-payment, so you might not be able to see things clearly inside the property with no lights.
Note: Yes, you can bring a flashlight, but based on experience, it’s not really effective.
This can make it unsafe/dangerous because there might be hazards inside the property that you might not see, like holes/excavations that can make you trip, or you can even fall into them (if big enough).
Also, if a foreclosed property is old and dilapidated, you might also encounter other things that are unsafe like debris, parts of the building that might fall on you, floors that might cave-in, and other hazardous things you might encounter.
I’ll show to you what I mean and explain further through the following short video (It’s less than 3 minutes long!).
