You say cast iron- rip all that out and replace NOT reline it will fail in 9 monthsMarketing and waiting carry costsContractor profit 10%Or are you handy enough to order everything and replace the electrical panel?

When I was selling residential solar I assessed 3-6 homes a day and often saw FPE panels with charring around where a breaker had been overheating for awhile and started arcing because it failed to trip, causing the breaker to melt and the wood framing the panel was mounted on to start burning.

He had sustained 100+ mph winds for about 8 hours and the only damage was replacing a few pool screen panels.

I'll let you know what I find out.Also, I'm traveling out to the DFW with my family in April (6-9th) staying in Tawakoni for the solar eclipse. 

I like to point out to my potential tenants that I added insulation or replaced a FPE electric panel to show that I don't just slap lipstick on my properties to make a quick buck....I would think the same would be true of appraisers.  

within the next 3 - 6 months duplex /triplex in or around my area although  the funds are week due to a high DTIalthough i have a 740 credit score, some larger purchases/ home improvements ,solar /roof /windows  have led me down the borrow pay later mentality..

I'm bringing in a panel of expert real estate investors with decades of experience across many different strategies.

What size is the panel? 

If not block is required you just need to cover the exposed home with hardi panel or vinyl siding.

Public electricity or solar panels?
