i have the opportunity to buy 16 lawns from a company thats giving up. the lawns range from $25 to $70. On a good year he said he made around $19800 OK then takeway for gas and wear and tear and the fact that every year is not a good one, some years you mow 28 and another you may only mow 24 and then every other expense of being in the lawn business. WHat should i be paying for these jobs? whats would be a good price for me and him. how do you figure out something like this?
