A dishelved single father sous chef battles a gambling addiction, when he blows the rent, the local heavy landlord threatens to put his son out on the street, with time running out he must recoup the rent and save his son from sale.

'Disheveled', I presume?

"When he blows the rent" is not a strong inciting incident because he brings it onto himself.

The goal of this movie is 'to pay the rent'. Despite the complications, it is not really an interesting premise.

And what is so interesting about the gambling sous-chef? There must be a very good reason to give this character this particular function. What is it?
