Custom-built houses?! Why not?

[Halid Parladi]

Hello Dear BiggerPockets family. I wish you have a great day.

I see that everybody is onto rental properties and buy low sell high strategy. Would not constructing your own custom house benefit you more if you were to sell the property? I do live in Canada, therefore, please make assumpitons on Canadian lands if possible. 

Let’s say a 1750 sqft house in Toronto. Everything is brandnew and cool. - Check up the houses that sell for 6 millions for example- Of course the construction company, or who maintains the property, makes profit out of selling the property, which I think the profit is around one fourth. Still, I would like to know how to calculate the exact amount to spend and to profit. Can you please enlighten me on this issue? Isn’t this a better way rather than working on buy and sell strategy?

Best Regards,

Halid
