Wood Walls in a flip????? What to do?

[Zach Ballou]

I recently looked at a single family home that I plan to flip. I’m putting an offer in this week and am trying to calculate my rehab expenses. The home is up the street from a lake and the interior of the home has a TON of wood. The cabinets are wood, the floors are wood and a lot of the walls are wood (vertical).  Almost all the wood is in good condition, but I’m unsure if keeping it is the right decision. It does give it a “cabin feel” , which makes sense because it is near a lake, but I don’t want to limit my buyers. I’m trying to figure out what I should do with the wood, mainly the walls. Do I keep them, paint them, or eliminate them completely? Is there a way to modernize it ? I have attached several pictures.
