Flipping house in north east with no insulation

[Nelson Del Castillo]

Hello I am under contract to purchase a bank owned single family home in Connecticut. As I was doing my final inspection I realized there is no insulation in the walls in about 60 percent of the house ( the exterior walls seem to be cement board) The only place that is insulated is the addition built in 1997. When flipping a house would you budget for adding insulation to the walls and if you did not would you end up selling at a lower price because of this. Any input would be appreciated. We will be updating the kitchen and bathroom but we are not gutting any of the exterior walls.

Thank You

@Christopher Phillips thanks.   We will be doing part of the siding so I’m thinking that adding 1/2 inch foam insulation panels on the outside of the house should be sufficient.  

 that would be a big plus when selling.
