Looking at homes built before 1990?! Take a look at the electrical panel. A large majority of electricians won't even service these panels and recommend replacement.
📌Avg replacement cost $1,300-$2,500
☑️ Federal Pacific (stab-lok)
☑️ Bryant & Challenger
That cost is for a panel up to 200amps and doesn't include the wiring within the walls, panel only. Let's talk about Federal Pacific specifically as they have a history of being the source of several known home fires. Knowing this early allows you to ask questions and gives you negotiation leverage. If you're the seller you can disclosure it and save time. Mainly in homes built 1950-1990. Look for Federal Pacific or Sylvania (which is most likely a rebranded Federal Pacific. However not all Sylvania are in this category), the term stab-lok, Zinsco, Bryant and Challenger.
📌 What if it's a condo or townhouse complex!?
- In this case you would need to know if it's your responsibility or the HOA but if it's the HOA why haven't they already done it? Do they have enough reserves? If it's the owners responsibility keep in mind you might upgrade your panel but what about the other five units connected to the structure?
