I love my home. It's a beautiful brick row house on the edge of a great city neighborhood, built at the beginning of the last century.
I certainly didn't love it when I first saw it: a run-down duplex that hadn't been treated well in years and years. But after enjoying the rent from our tenants for a few years, we fixed up some areas, ripped out and started over in others. It's unrecognizable from it's decrepit past, yet maintains the important historical moldings, and some of the room layouts.
This was our first home as a couple, and it's the house that my children came home to from the hospital. I know every nook and cranny, because I made it.
However, it is missing one thing: outside space. Grass. Room for a table for four.
Yes, we have a garage (huge deal around here!) and a small backyard postage stamp, which we have made the best it can be. But it's still tiny. It's still paved.

This is not my house, but you can get the general feeling from it.
Frankly, I never thought I needed more. The house is more than generous in size, but I'm getting more than a little tired of not having a backyard to send the kids out to, having to pack up a bag or car to get to an actual green space. I want to dig in the dirt and grow beautiful flowers, I want the children to climb a tree and maybe even fall! Thus, I've been looking at "house p*rn" for about 2 years now, and we've put an offer on one house...it was perfect. It obviously failed. And yes, I'm still bitter.
I'm okay with leaving this house, but I'm not so hip on leaving the city. Nothing wrong with life in the 'burbs, it's just not for me.
Thus, my choices are limited.
I recently came across a great old farmhouse, a la Martha Stewart, that's still within the city limits, but not really a walking neighborhood. It's on a beautiful acre lot, hosts some magnificent old trees. The house has charm, very different from my big-moldings home now, but a quiet charm full of natural light. Oh, and some awful 1970s remodeling.
Awful. Awful. Not livable. As in: must-renovate-before-moving-in-type-bad. But the price is right, and this house with renovation would equal out with the sale of our current home.

Nor is this the house I'm contemplating, but you get the idea. Imagine a similar house, in a city neighborhood, significantly more run-down, but with great potential.
There are kids on the street, great potential for a beautiful home and crazy-big yard (by city standards, that is!), and definite livability. But no place to walk. Wait, I already said that. Yea, that's because it's important to me.
Alrighty, that's where I'm cutting this one off. If you've read this far, I commend you. This is therapy of sorts for me, and I'm hoping after writing it all out, I'll come to a decision.
I'll continue later with Option #3. Hint: it's not moving to the 'burbs.
