A good friend of mine mentioned to me today that after 18 years of part time mowing he's not going to do it next year. He only has about 10 residentials, 5 decent sized commercials, and a couple large groups of duplexes. This year with just mowing alone he said he did about $30,000. The 5 commercials and duplexes are on 12 month contracts and the rest are just billed monthly. My question is how much would something like this be worth??
