Hi Marcus, your neighbor is giving you extremely risky and flat-out incorrect advice, and you are right to be skeptical. In real estate, the down payment amount you state on an offer becomes a contractual term in the Purchase and Sale Agreement. While sellers often favor offers with high down payments because they signal strong financial health and a lower risk of the loan falling through, claiming a 50% down payment when you only have 10% is a misrepresentation of your financial terms. Doing this intentionally to secure an accepted offer can be considered contractual fraud, and it puts you at immediate risk of losing your earnest money deposit, being sued for breach of contract, or having the seller cancel the deal entirely once the truth comes out. Lenders do not simply accept whatever number you write on a purchase contract after the fact; they verify every dollar of your assets. When you apply for a mortgage, your lender will mandate full asset verification—requiring bank statements, investment account records, and proof of funds to confirm that you actually possess the down payment and closing costs stated in your application and contract. Furthermore, your lender sends a pre-approval letter or formal loan commitment to the seller's agent specifying the loan-to-value ratio and financing terms. If you attempt to switch from a 50% down payment (a 50% loan) to a 10% down payment (a 90% loan) mid-transaction, your lender must re-underwrite the loan, which changes your interest rate, monthly payment, and requirements for Private Mortgage Insurance (PMI), while also triggering a mandatory update to the seller that reveals the discrepancy. Trying to game the system this way almost always backfires during the escrow period. Sellers and listing agents closely monitor financing milestones, and any sudden change in your loan structure or down payment amount gives the seller the legal right to declare you in default or refuse to sign loan amendments. Rather than using deceptive tactics that jeopardize your earnest money and reputation, the correct way to present a competitive offer with a 10% down payment is to show exceptionally strong pre-approval credentials, offer a solid earnest money deposit, keep your contingency timelines tight, and have your lender directly call the listing agent to vouch for your solid financial standing.
