Legitimate cash buyers can prove it. Ask for a bank statement or a lawyer's letter confirming funds before you take an offer seriously, and be wary of any buyer who wants to skip the $400 to $600 home inspection or rushes the condition period, since that pressure often hides a lowball number underneath a fast timeline.
Working through a licensed REALTOR® gives you a documented paper trail and a negotiated, agreed-in-writing commission rather than an informal handshake deal with an unregulated buyer.
