From a lenders perpective it depends on 3 things primaraily 1. Front end ratio - which is %tage of your gross income dedicated to pay your mortgage=principle+interested+tax+insurance...a general rule of thumb is 28%, in your case = 16800 a yrs = 1400 month. but nowdays some lenders even go upto 40% coz they wanna lend you money, they care about themself not about your financial goals. 2. Back-end ratio - debt to income ratio, general rule of thumb is , shouldnt exceed 36%so in your case, 21600 a yr, 1800 a month - 200 for your student loan = 1600 a month 3. a down payement of atleast 20% reduces, which has a direct impact on your mortgage and so forth in your FE and BE ratio.
