Is "now that" usually used as the beginning of a sentence?

From a post https://episode.ninja/series/joey

Joey decides to buy a house now that he is bringing big bucks from the movie but can he convince the owner of the house that he should get it?

Should I separate it into two sentences?

Yes, you can use now that at the beginning of a sentence.

You may also use it in the middle and at the end of a sentence.

It's main position seems to be at the beginning of sentences.

I think it looks OK. However, I would place a comma before but.

I got it. Thank you so much. That’s very kind of you.

Consider replacing the conventional "now that" with the technical SINCE.
This introduces the description of what is observed to be the case, and may be a cause

Then seek the beginning of the description of what may be the corresponding effect.
That description may most-unambiguously be introduced with SO, or merely marked with a comma, leaving the work to the reader.

SINCE
the cause did SO occur
SO
the effect did SO occur

"Now that" the cause did SO occur, the effect did SO occur.
