I tried posting a similar question in the landlord forum, but I didn't get a response that really spoke to the legal/liability issues with electrical work.I know I need a licensed electrician to do any work in the main panel to avoid a liability issue. 

I use the rapid lead paint testers on older homes.I also check the electrical panel for those that no longer meet code & check for a heavily corroded bus bar.

Electric panel is overheating, and appliances are not included.

I put solar panels and a tankless water heater to minimize utilities since they are not truly split.

@Rebecca Cramer I see shower wall panels in hotels often.

I’m in northern New Hampshire and we made homemade solar using YouTube and we’re able to achieve 85 degrees for much of July and august, our big swim season with just 3 homemade solar panels.

In my area, to consider a room as bedroom, you need to have closet, either built-in or standalone (some Cities prefer built-in only), should have a  HVAC vent, but no water heater and no electrical panel in the room. 

Updated electrical panel, new water heater, reconfigured kitchen with new doors/drawers, new countertops, new sinks, new plumbing fixtures, new appliances(seller provided), new flooring, new interior doors, new vanity, detached single car garage, new garage door opener, and newer heat pump.

I currently have a 100 amp fuse box that I want to upgrade to a 200 amp circuit breaker panel. 

Just curious, have you seen any investment property that have solar panels?
