Financing question (Canada, Montreal)

[Cloud Renji]

I have found 3 very similar properties all in Montreal. I just can't figure out why the down payments indicated are so different for each one.

Costs 950 000$ and requires a 454 000$ down (47.789%)

Costs 1 100 000$ and requires a 525 000$ down (47.772%)

Costs 970 000$ and requires a 339 000$ down (34.948%)

Very confused. Thanks.
