Or I could move

My architect neighbor, who I admire and adore, and his partner came over for dinner. The purpose besides neighborliness was to talk about possible additions to our homes. These additions would not show up until well into the future (ie when we pay off our second mortgages).
We were talking and though it I believed I heard their concerns. From what I heard I understand it would be preferred if I didn’t build to the property line. Ok. Well I guess I have to scratch a certain idea. Oh well.
The thing that got me was the ballpark figure given for what I’d like to do, with smaller footprint. $300,000. Dang. For that amount of money I could move. If it does cost that amount I would move into something newer and roomier. I was thinking $100,000 and that’s taking in cost overruns and working around the kitchen. The price I heard for some other neighbors to put on their addition, $35K, maybe I could do it in my range.
He did suggest something I will take into consideration, doing one side of the house. The additions I want would be for the back of the house. He suggested doing what I need to do to the front of the house first. Fixing the windows and doors and expanding the space of the bathroom. Ok. That sounds do-able.
