Vacancy Cost and Leasing Pipeline Tracker

Every empty month is rent you will never get back, plus the service charge and costs you keep paying. This app puts a number on it and helps you decide what to do.

Add units with the asking rent, the monthly costs you carry while empty and the date they became empty. Log each enquiry with its source and add the viewing, offer and signed dates, or mark it lost with a reason. The Overview shows the cost of one empty month and the amount lost so far, the vacant units with flags (no enquiries yet, over your slow threshold, signed but still marked vacant), the leasing funnel with conversion rates, which sources bring signed tenants, and the days to let and the discount you gave on units already let.

The Discount or wait tab compares two plans over the same period: hold the price and wait a number of days, or discount and let sooner. It shows the net income of each, the biggest discount that still beats holding, and the number of waiting days at which discounting wins, plus a table of other discounts. The day counts are your estimates (a button fills the wait from your own average days to let), and the leasing fee is your own entry.

What is inside:

• Overview, Units, Enquiries, Discount or wait and Settings tabs
• Example data: 8 units and 25 enquiries, made up
• A4 print of the overview, README, CSV and JSON import and export
• Discount or wait results checked against both a formula and a numerical search in 60 random cases

How it differs: the real estate agent tracker in the catalogue follows an agent's sales leads and commissions. This follows a landlord's empty units and the cost of leaving them empty. The portfolio dashboard shows rent lost to vacancy as one tile; this goes into the cost, the pipeline and the decision.

It does not predict how fast a tenant will come, does not model renewals after a discount, and does not post listings or message prospects.

This is a working tool, not legal, tax or financial advice, and it is not connected to or approved by any government body, regulator or bank. The app stores data in the browser on one device, so back it up with Export.
