The only thing one broker told me that kind of made sense is he was offering a plan with a guarantee of being about to buy more... his pitch was buying now was insurance against not being able to buy later...
Ultrarunner, this is true, but....if you qualify for a relatively inexpensive policy, you'd be better off buying another hundred grand or more of coverage up front, as "insurance" pun intended, if your needs change. The rider to guarantee additional purchases has a small charge, not bad, but when you buy more, you pay the rate at your then attained age, not the age you took out the policy.
it's really important to know how healthy you are. Buying life insurance is a major wake up call for folks who haven't had a physical before. "Your" hypertension plus elevated sugar levels, thirty pounds overweight, and family record of heart attacks may not be much in themselves if you are slightly over the limit, but put all those risk factors together and if you add smoking to that too, you may get a quote back that's half again more or even double what you had hoped for. Always buy insurance when you are at your healthiest, which seems counterintuitive, but boy will it save you money long term. Might not save your life though... so working on your risk factors is even more important.
that "buy more" provision" is only a nice to have and saves you the aggravation of possibly needing to requalify years later at higher rates because your health factors have changed. When you are talking a difference in hundreds of dollars yearly vs. thousands, buying more at inception just seems more sensible to me. They can't take it away from you...get it while it's cheap.
