A lender would likely approve you up to $185,000
On $60,000 of gross income with $550 of existing monthly debt, the 28/36 rule supports about $1,250 a month toward housing. With $37,000 down at 6.65%, that reaches roughly $185,000 — a $148,000 loan at 20% down. Your resulting debt-to-income ratio would be 35%, and you are currently limited by the total debt.
