Slumlords. Would you work for them?

I recently had a couple from LA contact us for a few bids on some of the rentals. They have here in Oklahoma. The slumlords live in LA although they are Israeli born. All three houses need extensive work the worst being the house needing to be leveled set on concrete peers and the entire subfloor and flooring replaced. Another one needed a bedroom rewire as one of the tasks and the tenant told me they had not had power in that room for three years. She also had her child’s room that had black mold and a leaky bathroom. The bathroom is probably just the wax ring on the toilet. Why did they wait so long to send a contractor? The third house did not have the HVAC working for over eight months and a huge giant hole in the porch. That house was also very unlevel and the floor was breaking and popping up. I’m pretty sure I don’t want to work for these people I’m feel like I wouldn’t get paid. What would you do?
