Ok, I'm thinking of outright turning down this job or requiring payment in full before I even schedule it. Here's the deal: Got a call for a cleanup and mowing. Single family residential couple miles up the road. Needs a cleanup, fall cleanup obviously wasn't done. Place is rented out and for sale. I had a funny feeling about this guy so I did some research. He has a very very unusual first name and not a very common last name. His phone number is a cell, so no info from that. Looked up his home phone, his address is listed as a PO box. Looked him up on the state small claims site. He's listed there for a case in 2006 for stiffing a real estate appraiser...judgement for the appraiser. 2 other people listed as being his household members also have small claims actions against them. This is a small job, maybe $200 including disposal. I'm really busy right now and don't think I'd miss the income but really hate to turn down work. I've never asked for 100% payment before doing a job but I think that's the only way I'd do it. But how would I explain why...not like I want to tell him I looked him up and that I don't like his address is a PO box, he's been sued in small claims and so have his family member and I don't trust him. Is it my imagination, or are there a lot of red flags here?
