Does property flow matter more than size?

[Joel Burt]

  I am getting ready to make an offer on a multi-unit property but I'm torn between which is more important: flow or size.

Flow

  I'm considering a 2-unit property in downtown West Chester, PA. The property was converted from a large corner townhouse into two separate units. As a result, the bathroom in the first unit is located at the back of the unit. Specifically, you must walk through the living room, kitchen, bedroom, and office to get to the bathroom. Obviously, this is not an ideal layout for the apartment. The flow of the second unit is better, but also not ideal.

Size

  Despite the above issues, the property is approximately 1.5-1.75% larger that other townhouse selling in West Chester at the same price point. 

  Which is more important? The flow of the property, or the size of a property in a town primarily composed of small 100+ year old homes? 

Thank you!
