Check your credit report (3 agencies) to see if you have student loans showing as of yet.
If not, you might be able to buy before they do.
Yes, the student loan monthly payment is counted as a monthly expense. It will reduce your buying
potential. The bigger the payment - the lesser the loan you'll qualify for.
Make an appointment with a mortgage pro and find out how much you can get a loan for,
then meet with the realtor to see what you can buy with that loan amount.
In preparation for your purchase, save up for your down payment, closing costs (sometimes those can be covered by your seller), move in expenses, insurance and reserves.
Hope this helps,
