It was built In 1950, and refinished floors, paint, nice dual pane windows, but....the slight sign of clutter makes it look like a disaster.

Similar to you Danielle and you Ibrahim, after reviewing your website,  my goal is to have my RE investments serve dual purposes, improve communities as well as earning returns on my investments.  

I'm looking to buy a rental property and there is one house which numbers seem to add up for my scenario except for one thing: there are high voltage power lines running through the lot (more on the backyard and less on the house).

It would be dual house hacking, while you rent out the other two units. 

The place has dual exterior storm windows.

When we built condos we would get warranty complaints which included the wolf oven took to long to heat up (though it was taking the time it mentioned in the manual), that the dual flush toilets do not work (I had to get a letter from Kohler about how much you know what is typicaly in a flush and what it could handle).... 

If there was no buyer's agent, the seller has to sign dual listing paperwork that he understands and agrees with the risk this poses.  

SC I believe is a dual agent state and I know I would have to watch out for my own interests, but I'm good with that. 

I don't think you need to have this person act as a "dual agent" per se.Said middle man just need to make a flat fee or percentage rate of the sale agreement with the buyer, then introduce you to he/she. 

Also above ground, I could show you one of my properties where a tree branch literally grew around a high voltage electric wire; it was cut off on both sides and now there is just the branch stump hanging off the wire which goes through it ...
