Don't just weed, use Round-up! (In some cases.)

In writing about general economic trends, "позитивная динамика" often means simply "growth." Your sentence doesn't provide enough context to tell what "the situation" is, but quite possibly the whole sentence could be expressed like this:

There were indications of growth throughout the year.

There were indications that growth had resumed, throughout the year.

(The "had resumed" is based on a guess about what the context might be. Of course it might be something different.)

With your additional info that it's the real estate market:

of growth
of recovery
of an improving situation

There are lots of very concise options.

Too many "weed words" in your translation--get rid of them. You don't give a context except in your classification of the Kudoz, so my answer assumes that you're talking about the economy. If you're talking about a company, then you'll have to adjust it: financial trends have been positive, or something like that.
