Building Cost
Purple is by far the best for farming. Realistically, anyone can collect once every 3 hours. Brown house gives too little and no one is there frequently enough for that. The other houses don't pay out nearly enough per day.

It depends. Sure, you might be able to gross more from Purple - but if you miss a couple of collections then you really aren't netting that much now, are you?
Personally I prefer white houses. You can pack twice as many into the same square of land, and hitting my game twice a day is pretty easy so I net far more with them than the others (and I've tried purple and blue, and brown for about half a day before saying "nuts to this").
Initial cost is pretty much irrelevant - over time I will obliterate any initial cost difference with the dramatically better long term income.
