can i do this?

so... i have a meeting today after work, with my mortgage lady. i'm moving to getting pre-approved, so when i do find the right place i can jump on it!
i'm young and scared a little, so i just want to make sure everything is ready to go for me to make an offer on a house. there's one i've been watching... it's too high right now, which sure they put a lot of love into it... but it's only a one bedroom. i'm hoping they're ready to come down in price, i'm going to try to see it this weekend. its hard for me, soon as i step in a place i can see all the potential, what i can do with any place and i have to hold myself back and figure out what really is a good investment and what i can do with out going too over board.
it's exciting though. i've always wanted my own home... i plan to take off work once i get a place, i have vacation time saved so i can paint the walls, then move all my stuff in, and finally, relax! my own place, home. that's it, no more moving, no more landlords, mine, me. i'm the one that cares about the house, maintenance and condition. i won't have to move, and i won't have to walk away from a house i love.
i still miss my kansas city house, it's been town down, but that is what i want here. this time i'll own it, and it won't become abandoned cause the owners went bankrupt and the city then came in and tore it down. that little house is the first place i lived that felt like a home, that warm fuzzy home feeling, but i didn't own it and it went away. i feel a little heart broken over it so this time it will be real, it will be mine, and no more white walls! i love white trim... hate, hate, hate white walls!!! i know that is a silly reason to get excited for owning a place, but for me it will be so nice, that's what really makes it feel home claiming your walls.
6.5 more hours till i meet with mortgage lady for the application process... i have all my papers ready to go. i'm so excited and nervous but in a good way. i've always wanted a house, my house, and even though i think i'll travel and live in other cities, if i'm going to buy anywhere i want it to be in my home town. this way i will always have a place here and am invested in my home town. if i'm buying property anywhere i want it to be here. especially since with the market i plan to have it for at least 10 years, ideally i'll keep it forever and maybe buy more houses far down the road.
