Thanks for the concern bro. But I cannot think any other way to improve score.
Bro, as your brother, I'm telling you, do not go ahead with that. Instead, try the student route.
A friend of mine recently lost CAD 6000 in Regina, Canada. He was fooled and looted by a phone call pretending to be an immigration officer or something.
He too is a student (will be graduated by this December) and I know how hard it was to earn those bucks.
So I request you to not go ahead with this even if it is 100% legal. A property or land or a plot is the identity of your family
Try every option to improve your CRS. Rather than selling your land, invest about 60K on French, and study for about a year. You will gain 30 to 40 extra points.
If not, it is really safe and best to go via the student route.
In the meantime improve your skills, Personality Development, and others while you are ready to rock as a student.
Hope you really consider my opinion.
