Home inspection, negotiate further or back out?

[Cory Lucas]

Offered accepted on what will be a BRRRR deal for me, just had home inspection done today and it's a little worse than I expected.

Any tips on going back to the negotiating table? There are some structural issues, a few sections of floor are rotted, some mold in drywall where there is water possibly leaking down the wall, and a ton of water in the crawlspace that will need some sort of drainage installed

Or should I just walk away from the deal? I would just be out my inspection money and $500 earnest money and I’m not a fan of doing that and upsetting my realtor, but at the same time don’t want to get into a money pit

Thanks in advance for help/advice
