CLUSTER ESTATE-FINANCIAL-INVESTMENT · 23 ENTRIES · EARLIEST ENTRY 2025-08-22

Real estate investment calculators

This cluster consists of web and mobile tools for real estate investing, covering tax deductions, cash-flow analysis, ROI, and deal evaluation. Dated entries are sparse: one from 2017, then several in 2025 and early 2026, so the timeline shows a sustained spread rather than a concentrated launch period. Bradley-Quant-Finance-Software-Engine leads traction with a single star, while all others trail at zero stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
