Looking at houses

So, the agent sent me a listing of a few houses that were on the market that matched what I was looking for. I looked them over, and at first didn't see anything that looked like what I wanted. But at the time, I was at work, and the agent was on the phone and I just felt kinda rushed, didn't really get a chance to look. So I took some time and looked over them again and found 3 that I thought might actually interest me.
Yesterday, The Boy and I drove past them all. Checked out the neighborhood and the general house from the road, to get an idea if they're really be something worth looking deeper into.
The first house we drove past (3485 Bethesda) was a more recently built house, it was in a subdivision that was very secluded. The houses there were a little bit close together for my tastes, but it seemed like a good place. It was walking distance from a park, but the commute might not be the best. This house warranted a look around inside.
The second house (498 Cole) was a bit older, it was off a semi-main road, not a whole lot of traffic, but there's potential there could be. It had a rather large yard, front and back, and lots of space around it. We didn't get to look too close because of traffic, but I would like to go see the house more.
The third house (657 Mountainbrooke) was in a secluded neighborhood that is directly off a very busy main road. This house wasn't in good shape, the front yard was mostly weeds, and the back appeared to be too much dirt. There was an odd island in the front that looked like it would be hell to maintain. The house backed up to a small lake, which looked like it would be a bad thing in the summer and just breed mosquitoes.
Of the three, I've informed my agent that I'd like to go see two of them, so hopefully we'll get a chance to look back at them this weekend.
