Source please? Hint, most single-component polyurethane cures in the
presence of moisture.

If it does then your method failed.

10 years is not long in the life of a house.

So you want the OP to live in a hotel for _how_ long?

In an earlier post you recommend BIN, which is dewaxed shellac, or Kilz,
which is marketed as an alkyd coating purpose made as a replacement for
shellac. Now you're saying that if you use shellac then the odor will
reoccur. So which is it?
And I did not say to use only shellac, I said to use it as an odor barrier
and then put whatever you want on top of it, which includes polyurethane.
I don't see why you're having a problem with that.

Oh, a realtor. Now there's an expert for you.

If this is in fact a recognized "professional approach" then you should be
able to reference a standard of some kind that says so, or literature from
manufacturers of polyurethane coatings recommending them for this purpose,
or some other such source.
So a realtor taught you a trick and on that basis you're sure that it's the
only viable approach.
Believe what you want to. Meanwhile I'll go with the standard method, which
is to apply a shellac odor barrier and then an appropriate coating.
