Stress-testing the math behind a 3,800-letter land mail campaign before it goes out
Before a first mail campaign on land goes out, it's worth having the math checked rather than finding the weak point months later. Say the list is county records, absentee owners with a mailing address outside the county, 5 to 40 acres, no improvements on the assessment, 3,800 records after duplicates and bad addresses are removed. Print and postage on plain yellow letters runs about 0.62 all in, so 2,356 per drop. Three drops to the same list totals 7,068. Published figures put land mail response in the 3 to 5 percent range, higher than house mail because owners are more detached from the parcel. At 4 percent across the campaign, that's roughly 152 responses. If 1 in 12 of those becomes a signed contract, that's 12 contracts. If half close as assignments at an average 8,000 fee, that's 48,000 against 7,068 of postage. The number with no basis in this chain is the 1 in 12. It's an assumption that feels conservative but isn't backed by data. The other soft spot is anchoring offers at 30 percent of assessed value, since assessed value is the only figure available for all 3,800 records at once, and assessed value is not market value. Of the two, the assumed close rate is usually the weaker link, since it compounds every error upstream of it, while the assessed-value anchor at least produces a consistent, if imprecise, starting offer that gets corrected during negotiation.
