A lender would likely approve you up to $199,733
On $74,000 of gross income with $550 of existing monthly debt, the 28/36 rule supports about $1,670 a month toward housing. With $32,000 down at 6.65%, that reaches roughly $199,733 — a $167,733 loan at 16% down. Your resulting debt-to-income ratio would be 36%, and you are currently limited by the total debt.
