Property Clues is a UK toolkit of browser-based calculators and trackers for landlords and property investors. It covers the jobs landlords do every year: checking whether a buy to let, BRRR, HMO or commercial deal stacks up; tax under Section 24 and whether a limited company would pay less; getting ready for Making Tax Digital; tracking expenses, rent and arrears; keeping certificates and compliance dates in one place; and the new Section 8 rules after the Renters' Rights Act. There are 12 free tools with no sign-up. Paid tools start at £19, or every tool comes in the Founder's Pass for £199. Every price is a one-off payment, with no subscription and no per-property fees. Every paid tool has a free preview to try first.
Property Gauge is a performance management platform built for multifamily owners and operators who run more than one property management system — or one system that won't give them a portfolio view.
THE PROBLEM IT SOLVES
Most multifamily operators are data-rich and insight-poor. Occupancy lives in one system, delinquency in another, work orders in a third, and the weekly rollup gets assembled by hand in Excel. By the time leadership sees a number, it is two weeks old and two people have already disagreed about whether it is right.
HOW IT WORKS
Property Gauge connects to your existing systems — Yardi, RealPage, Entrata, AppFolio, ResMan, Rent Manager, plus custom connections — and consolidates their data into one dashboard. No workflow changes, no migration, no asking site teams to enter anything twice.
What makes it a performance management tool rather than a reporting tool is the standards layer. You define the benchmarks your company actually holds properties to. Property Gauge
