There is a lotthat goes into the finacial descision that will determine how much they will loan you. Things like how long you have been at your job, did your recently graduate, are you single or married, consistancy of income (like if you work at a commision based job and do great one year and bad the one before that...), and sometimes even what job you are doing. In my situation, I recently graduated, had 24k to put down, and was at the middle of my second year of my job(39,800), and they cleared me for a loan of 80k in a couple of weeks. no problems or hassles... I don't know about my rating or anything like that, but I feel that if I had tried for more, I probably woul dhave gotten it...
P.S. that quicken thing isn't very good, i put in the same info i have here at 1000 for bills, and the info it returned was all right, but who will get a house worth less than 50k? Or perhaps So cal living is high? 200 for the monthly payment? I pay more a month for my truck...
