First renovation and rehab questions

[Theodore Williams]

Walkthrough
Hey everyone! I just closed on my first house Friday and am doing all of the work myself with my step dad. He has been working on properties his whole life so he’s a great resource and partner on getting the work done but as this is my first purchase and reno, I am looking for a few suggestions on finishes so I can finish working out my numbers.

The house was bought from a local investor who seems to have run out of money and was offloading about 3-5 properties in my area. I was able to get a good deal on the house I was interested in due to this fact but it’s a half done flip/reno so there’s a lot of work halfway started throughout the house. 2 areas in particular I’m unsure of what to do with is the walls and attic, any suggestions or ideas of how you would be finish would be greatly appreciated (adding links to specific products are a bonus lol)!

Attached is a picture and walkthrough to give some ideas but is anyone aware of what kind of paneling is used on this wall and where to buy (picture)? I like it and would be interested in continuing it in the dining room but can’t seem to find it anywhere? Also would something like this work throughout the whole house or only specific rooms? Any suggestions on anything in the video would be greatly appreciated!
