I could not see indication of whether there is a basement. A basement can make a small place feel much bigger as you can store rarely used items down there. The closets are likely tiny. If you can put out of season clothing in the basement that will help. Large kitchen items, large hobby items, many tools, seasonal items and even cleaning supplies used weekly can be stored in a basement.
One "big" thing to think of is fitting in furniture. Today's furniture is huge compared to how much of it was made back when this house was built. I (small house owner) do much better buying my furniture from the "nearly antique" stores. It is fun to pick out furniture that is now unique in the market, and we have taken our time doing it, extending the pleasure of the search and acquisition for
years.
Hey, do I see a fence gate opening into the yard next door? If so, that probably means someone has been a very good neighbor--maybe even family to whomever lived in this house. If you find yourself really interested in the house, you might knock on their door and see if there is anything they'd like to tell you....I mean, if they have a gate between yards...
