Should we?

Recently Jake and I have been presented with an offer that is almost too good to refuse. A couple in our ward is selling their house and they are willing to sell it to us. Now this is SELL not RENT! We have been crunching the numbers (at least Jake has I just nod my head like I understand it all), and it looks like a plausible thing for us to do. The real question is, should we? This is a major step, no I take that back. This is a leap into the abyss. Me being the worry wart that I am causes me to be terrified. Granted I am terrified with just about anything that requires me to step into the unknown. I just fear we wont be able to swim and end up sinking and ruining any chance of keeping our good credit, and money for that matter. But on the other hand if we are able to do this then we can start to build that equity foundation and have the ability to really start to being more independent, more or less. It is just so tempting with the market as it is. This house is an awesome starter home, it is still within our ward boundaries, close to UVU, and we can not have freedom to decorate and do what we want to our home without fearing that we will lose our deposit. I am not going to say that we wont do it, but there is always a part of me that is hesitant. At this point we have, namely me, have put this in the Lord's hands. If He wants us to go with it He will provide us with the needed opportunities and peaceful feelings that this is right for us to go with. I trust in Jake and the Lord, they would never steer us into something we couldn't handle.
I guess I shouldn't worry and just let things come and be grateful with whatever happens
