I closed on the property a couple weeks after.Some items off the SOW include a new roof, new windows throughout, electrical and plumbing rough-in, new kitchens and bathrooms, move the 2nd floor entrance to new location, sidewalk repair, 200 AMP panel and separate electric and gas meters, forced air heating, and new 12 mm laminate flooring throughout, among other items on the 3-page list.

My question for this panel is this a widely accepted practice among investors, or a lower percentage of people who see this as a wise thing to do.

You mean solar roofing or solar panels on top of the existing area?

Stained wood plain doors throughout, and they put a white panel door on. 

Is the panel grounded correctly?  

I was planning on using 4 x 8 mdf beadboard paneling and gluing/nailing it right over the wallpaper and plaster.

The last time we had a tenant who offered to pay extra money up front, I got a call from the DEA, the front door was smashed in, frame was cracked on the jam, carpet was destroyed and the basement had been turned into a commercial growing operation with sub panel screwed threw the wall for feeding to the pump system.Why not pick a tenant where they are not going thru a divorce, less potential headaches?

I bought a house that had a fence panel down from the neighbors fence.

This is usually called "Forwarding" and is found under most control panel/manager areas of the major players such as GoDaddy.com.
