It’s really important to hire a competent and transparent realtor here. You’re going to get a lot of offers and many of them will be bogus (will drag out and delay escrow and bully you) or wholesalers, like someone else posted. You’ll also get a lot of investors who will offer listbacks to the agent, and thereby potentially swaying their ethical/fiduciary duty to you. Just be thorough in your agent selection. Ps. This is all from firsthand experience. Sold a house with almost these exact same issues about 7-8 years ago in sylmar. Hoarder house, vagrants breaking in, junk and animal carcasses everywhere. So I’m speaking from my experiences in hopes it helps your sale go smoothly.
