Master off the kitchen???

[Eric Armstrong]

I'm looking at a home that has an addition off the back of the house(used as an enclosed porch) and is accessed through the kitchen. The home was built in the '50's and is a 3/1 without the ability to make it a 4/2 without converting the addition to the master suite. Seems weird to have the master off the kitchen though. What are your thoughts? Thx
