Congrats on your production, most agents do not stay around long enough to figure it out. The key to writing 150K per year is having a consistent flow of new leads per week(preferably 20 direct mail leads). Its tough for a lot of agents to consistently afford 20 leads every single week, that is why companies like LH finance leads for their agents. You have a good lead cost, as long as you have a competitive contract(least 100%), you have a protected territory, so I think you are in a good spot. The Agency that I am with provides exclusive direct mail leads for $24.50 with a 100% contract. The cost for the leads are deducted from commissions. The lead financing has helped me maximize my production. Some companies have great leads with low comp, or great comp and a substandard lead program. You have to find the right combination.
Good Luck
$24.50 per lead at only 100% is not really that great, some others have better deals. I'm in a program now that is better, not bragging just saying.
