I can buy a house?!?!?

I'm dealing with adult-hood. Funny, since when I was little all I wanted was to grow up, drive, date, go to college. My driving had me in defensive driving this morning. I'll not even start on the roller coaster that's my dating life (or the lack there of), but I am ridiculously blessed and am getting ready to start an amazing job using the entirety of my college degree. So now what's left? Housing. Need to move closer to my job. Found a wonderful starter home to buy and went to the bank to see what I could be pre-approved for. I am pre-approved for the house. Of course the monthly payment at the price is 50% of my monthly net income, but apparently I am adult enough to be able to afford the mortgage. Growing up is scary. Luckily God is always good and if it's His will He'll give me the money to afford their bill.
"For I know the plans I have for you, declares the Lord, plans for welfare and not calamity to give you a future and a hope. Then you will call upon Me and pray to Me, and I will listen to you. And you will seek Me and find Me, when you search Me with all your heart." Jeremiah 29:11-13
