Living room, kitchen, master bedroom.

I would chose the kitchen, family room and master bedroom. I would do the front of the house if you considered that a room as everyone wants their home to have curb appeal. 

Depends on what you trying to accomplish with the ad. Normally, for the regular flyer type ad, it would be front of the property, kitchen, master bathroom/backyard (whichever has better photo). To drive traffic back to your page just pick 3 most impressive pics and have them look for more on your page.

Kitchen, Master & front exterior

I would have only one room photo and that would be the kitchen. The main photo would be of the home from the curb and last would be the view of its rear exposure. In essence all other rooms are squares or rectangles when all is said and done, they can be molded.   

The most prominent . Sometimes it's just the yard if there are no good interior shots. But I like kitchens  and LR or FR. Don't like bathrooms because of all the mirrors. 

1 front - curb appeal

2 kitchen - big selling point

3 master bedroom - buyers have big interest in mb

I'd say Front Exterior, Kitchen and Family Room.

Jillian - I am going to have to go with front of home, kitchen, and whatever the other best feature of the home would be for my 3 photos.

Outside front, Great Room, Back yard or kitchen...depends on which is nicer,.

I'd show the best and the most flattering pictures. If the house is not a mess, my pick would be: a kitchen, a living room, and how it looks from outside( curb appeal).

I would show the front, kitchen and living room. I hope I am never limited to that.

Front of the House, Kitchen and Master bath. 

Jillian La Rocque Exterior, kitchen and best feature of the home.

I would choose among the kitchen, master bath, living area, front and backyards depending upon which are most appealing.

Kitchen, backyard, family room.  Everyone wants to see those rooms.

Front, Kitchen and living room. That is the first 3 things most people look at. If was towards guys, the garage, the basement and the back yard
