We have been a supplier of OSMO Hardwax Oils for a while now and have found that they have been great in all applications. They have an Oil specifically designed for Kitchen benchtops. OSMO Top Oil which is foodsafe and contains linseed, carnauba wax, candelilla wax, sunflower oil, soybean oil & thistle oil. You can buy it from VCS Products in Perth or Natural Timber Oils in Melbourne.

Our last house and our current house both had wood floors and lots of wood furniture. Using area rugs (I've got a weakness for oriental rugs) provides separation between the floors and the furniture. And if the walls are light, as in LesleyH's photo above, you will certainly not feel overwhelmed with wood. The only time there's an issue in my mind is when the walls are also wood clad - that can be a bit confronting and needs management.

Is it possible that there are floorboards under the carpet that can be polished? This would be ideal. Otherwise, as much as I love my bedroom floorboards, I think you should stick with carpet. You’ll never match the hallway exactly so it will always look a bit odd.

If you were selling , are you sure you will recoup the extra $$$$ ? Get it wrong , and a potential buyer will walk and/or offer $50k less , whereas if you leave it as it is , they will know it needs replacing , offer $10k less , but you have gotten an offer ! Just me , but what I would do is rip up the fake tile lino in the foyer ( I assume it is lino -- it doesn't look to be 'proper' tiled ? ) , and do that in a darkish timber laminate -- slightly lighter than the front door , slightly darker than the stairs . Or go really dark -- almost a dark weathered grey or a similar dark brown to the drawer unit in the lounge -- the rest of the colourings will lighten it a bit , but it will all tie in . OR actually tile it , maybe a black or charcoal gloss marble or marble effect with lighter streaks through it ? The house and colourings look an older style , this continues that theme , but I feel white or beige tiles would look too bland . $2k max instead of $10k -- marble tiles may be more than $2k , but up to you .
