🔴 This home stretches your monthly budget too thin.

Even with a down payment, the $3,346/mo payment takes up too much of your monthly income. Try looking at homes around $280,000 instead.

Your total debt payments would eat up 50.0% of your gross monthly income (well over the standard 36% limit). A home priced closer to $280,000 fits your income comfortably.
