Your house, your decision. It isn’t ‘fine’ or historic. It’s just wood. I would paint it white and put hardwood floors everywhere.

It won't de-value the home. If the wood was redwood, mahogany, or the home had beautiful craftsman paneling that would be one thing. But this is typical builder-grade stained white oak that is not particularly appealing these days.

Paint it all. It will look so much better. But use a professional. This is a big job and it should be done right.

It would most likely reduce the value to me, but, for someone else, it would be a big plus. I do think it looks to be in great shape, but, its your house, and you need things, to be like you want. All my trim is painted black. It was painted white when I bought the house, but, I cant live with white trim. I am sure, if I put it for sale, there would be people who dont like the black, but, there will always be a buyer that will.

Oak can have a heavy grain, so if not painted correctly, and the grain is still visible, then I'd say that it could devalue the home. So - definitely hire a pro. Another issue - you have "short" baseboards. If you are going to paint the trim white, replace the baseboards with taller ones.

If white over the oak makes you happy, go for it. Just remember to sand and prime really well so the grain and knots don’t show,through. I would pick a different color for the kitchen after painting all the doors and trim. You May realize it is too much of a good thing so do one at a time. And remove the carpet after you paint. It will look dingy with white everywhere. Good luck and keep us posted!

IMO paint it but then I hate oak it is everyhwere and IMO not a good quality oak . If you have never painted cabinets I would strongly suggest you do not try it get a cabinet refinisher not a regular house painter and get the cabinets at least done right. BUT that kitchen is IMO not worth painting the layout sucks and you need to live there for at least 3 -6 months before doing any floors or anthing in the kitchen. I would also think about what you want to display on all those shelves . IMO remove the shelves put the TV above the cabinet on one side of the FP and a piece of art on the other side. That avoids the TV above the FP . I think I see popcorn ceilings IMO removing those is a must and the lighting needs to be addressed all of it should be LEDs in 4000K before choosing any color for anything. You should pobably think about getting an interior designer to help and an actual KD too.
