If you can’t identify a food you’ve never tasted before, the cliche answer is that it “tastes like chicken.”
That’s usually a safe answer, because, depending on how it’s prepared, chicken can taste like anything.
Oak floors are a bit the same way (at least to my eye).
I just previewed a home with what appeared to be striking walnut floors.
In fact, they were oak, just stained darker to look like (more expensive) walnut.
Nice way to save some money — and I’m guessing 9 out of 10 prospective Buyers can’t tell the difference (and won’t care!).
