Three months of daily calling before the first deal matches what I've seen too - the people who quit usually quit in week 4-6, right before the compounding kicks in. The 'find a method you can actually stick to' part is underrated - I've seen people pick the highest-volume channel instead of the one they'll actually do every day, and volume on paper beats consistency in practice every time.

The buyers-list point is the one people skip. When leads get expensive, everyone tightens up on marketing spend, but almost nobody spends that same energy re-verifying their buyers list is still actually buying at today's numbers, not the numbers from 8 months ago. A buyer who's ghosted your last two offers isn't part of your real buyer pool anymore, even if they're still sitting on the spreadsheet.

mine was switching from generic lists to actually pulling motivated-seller-specific criteria before dialing, felt like I was calling randoms before that and the plateau was just bad targeting disguised as a volume problem

Not an attorney, but I've dealt with a similar heirship situation, so take this as a starting point and verify with a title company/real estate attorney in Arizona before relying on it. 1) Splitting the land into two surveyed parcels does NOT by itself sever the co-tenancy interest. Unless the heirs signed a partition deed that specifically allocated each parcel to a specific owner, the undivided 85/7.5/7.5 split generally follows across BOTH parcels, not just one. A survey creates new legal descriptions, it doesn't reassign ownership shares. 2) Title companies almost never insure over an unresolved co-tenant/heir issue like this, especially with heirs who've gone silent for years - the risk of a later claim is too high for them to underwrite. The two paths I've seen work: (a) a quiet title/partition action, which is slower (months, sometimes a year+) but gets you clean title even without the missing heirs cooperating, since a judge can order a partition sale or unequal division based on ownership %, or (b) if you can actually locate and get the 7.5% heirs to sign, even a $500-1000 buyout each for a quitclaim is often cheaper and faster than litigation - worth one more real attempt (process server or skip trace, not just certified mail, which people ignore easily). 3) On selling just the 85% interest - some investors will buy an undivided co-tenancy interest at a steep discount, but it's a hard sell to end buyers and most lenders won't finance it, so your buyer pool shrinks to cash/investor buyers comfortable inheriting the partition problem themselves.
