Two years ago I started cutting neighbor #1's lawn. We didn't have a set fee, he would just give me a wad of money every 4 or 5 weeks. It was good. Last year I took on neighbors #2 and #3. #1 only paid me 2 times last year for a total of $15.50 per cut( his lawn is easily a $30 job). #2 didn't pay me until October,for the entire season. #3 payed every week. This year I said no more neighbors! I guess they think you like cutting grass so much that you'll do it for next to free.
