House hunting

I have decided I hate this. I know we have to move as this house just isn't big enough. I guess I kind of hoped we would add on but I know that just isn't the way to go. Adding on would be so much stress with us having a baby and who knows how long it would take. It is just easier to move. I just hate moving. I am also not looking forward to having to get our house ready to show. It isn't on the market yet or anything and we are just starting to look for places first. Our house should sell fast as it is a starter home so it is actually harder for us to find a place. We would have so much stuff to put in storage and then I would have people going through my house when I am not home. I think that is the part that bothers me. I don't want people in my house.
We have looked at a few places so far but nothing yet has made us want the places after viewing them. We are picky as we never want to move again. We are also trying to buy as cheaply as possible as we don't want to extend the mortgage by much. My parents and his keep saying that getting a 35 year mortgage now is fine and then when we have more money we can pay it down faster. I am trying to figure out where this "more money" that they keep talking about is going to come from. My mom said that I will get raises every year and that will help but the way I see it the interest rates will go up, property taxes will go up, cost of living will go up. All of that will be way more than my raises. Also stuff for Lauren won't be cheap with her special diet. If i want another child that will be more money. I am just not sure if I want to get into a 35 year mortgage especially since I only have 13 years left on mine now. We are looking at another place this weekend and we will see. This one is way high in our price range but it looks good so far so I am just not sure. It is also in Langley rather than in Aldergrove where the rest have been so it will be a stressful weekend I am sure.
