Hey Mikey-
It sounds to me like you are sitting on an iron mine. Actually, what you are sitting on is the dump. It really was a thing to build houses on "landfill" back in the day; I grew up in a house that was built on a 1950's landfill.
Unfortunately, what this may mean for you is there really isn't anything worth looking through the trash for, being that it's, you know, trash and all. By that I mean it's literally trash, the stuff that people threw away, not stuff people just left laying around. The chances of a decent find are fairly low.
And your current detector is not going to help. No Bounty Hunter detector is going to hunt that area effectively. Even the most advanced detectors out there regardless of brand are going to struggle in that environment. Giant chunks of iron defy discrimination pretty much across the board, and will mask any good targets. It's one thing to defeat masking by a nail or chunk of wire; a bucket or length of pipe is another story altogether.
If you choose to continue on your quest to detect this property, I wish you good luck. If it was me, I'd move on. With no history that would make me think there is a good possibility of good targets in this mess of iron and garbage, I'd spend my detecting time elsewhere.
