House Advantage Craps
You are actually giving the house a greater advantage by putting the dollar on the 12 on the Come Out Roll. Think about it like this: You are fretting over the very small edge that's already on the Pass and Don't Pass (1.37%) by losing a dollar on 35 of every 36 Come Out Rolls. The house advantage is 2.8%. Configuration #3: Pays triple when either a 2 or 12 shows. When the Field pays triple for both the 2 and 12, it’s a “zero expectation,” which means the casino has no advantage. Unfortunately, most casinos have tables with configuration #1 that pay double for both the 2 and 12 with a 5.5% house advantage. The odds bet is the only fair bet in the casino. Every other bet has a slight house advantage. The catch is that you have to make a passline bet (with a house advantage of 1.41%) in order to make an odds bet. In theory, 10x odds allows you to place less $$ on the passline bet and more money on the odds bet - which is much better for your bankroll.

* Note About the Odds Bets
While the house edge is in fact zero for the odds bet there is of course a catch in the fact that you have to have made a Pass Line or Don't Pass Line bet to be able to make the bet. The actual house edge on the combined bets is determined by the amount you can bet on the odds.
Typically online you will only find 3X odds which makes the combined house edge on the Pass Line Odds 0.47% and for the Don't Pass Odds 0.34%. The higher the multiple you can bet on the odds the lower the house edge so for example a game with 100X odds has a house edge of just 0.02%.
