My fiancée and I are looking to buy our first place maybe next year, I was hoping that I would be able to put 5 - 10% down and still get first time home buyer (cmhc site specifies primary residence, not investment properties).

Identify gaps in supply in that neighborhood and look at the property as a potential development site.

You can find a ton through Meetup site or here on BP.
