A lender would likely approve you up to $223,195
On $70,000 of gross income with $550 of existing monthly debt, the 28/36 rule supports about $1,550 a month toward housing. With $41,000 down at 6.65%, that reaches roughly $223,195 — a $182,195 loan at 18.4% down. Your resulting debt-to-income ratio would be 36%, and you are currently limited by the total debt.
