Edit Properties,
See Results Instantly
Every field saves automatically as you type. A live calculation sidebar shows purchase summary, loan details, NOI, cash flow, and key metrics -- all updating in real time.
Auto-Save That Just Works
No save buttons. No lost work. Every change persists automatically with intelligent debounce and instant visual feedback.
800ms Debounce
Text fields wait 800ms after you stop typing before saving. This prevents excessive server calls while ensuring your data is saved within a second of finishing.
Instant on Dropdowns
Dropdowns, radio buttons, and toggles save immediately on change. No waiting -- select an option and it's saved.
Per-Section Status Badges
Each of the 11 form sections shows its own "Saving..." and "Saved" badge. You always know exactly which section is being updated.
No Data Loss
Navigate away, close the tab, or lose your connection -- your data is already saved. Every change is persisted the moment it's confirmed.
Live Calculation Sidebar
As you edit any field, the sidebar instantly recalculates all metrics. Here's what it shows for a $385,000 rental property.
Purchase Summary
Loan Summary
Monthly NOI
Monthly Cash Flow
Key Metrics
All values calculated in real time from a $385,000 property, 20% down, 7% rate, $2,850/mo rent
These calculations update instantly as you type
No save button, no page reload. Change a rent amount and watch purchase summary, NOI, cash flow, and key metrics all recalculate in the sidebar immediately. It's like having a financial analyst looking over your shoulder.
Editing Features
Every aspect of the editing experience is designed to be fast, reliable, and frictionless.
800ms Debounce
Text fields wait 800ms after you stop typing before saving. Fast enough to feel instant, smart enough to avoid excessive requests.
Section Status Badges
Each form section displays its own save status. "Saving..." while the request is in flight, "Saved" once confirmed. Always know exactly where you stand.
Toggle Fields
Down payment, closing costs, and seller concessions can be entered as percentages or dollar amounts. Click to toggle between formats.
Conditional Visibility
The form adapts to context. Toggle "Already Owned" and ownership fields appear. The form only shows fields relevant to your situation.
Copy & Duplicate
Duplicate an existing property to create a new one with the same data. Perfect for comparing scenarios or analyzing similar properties.
Cross-App Data
Every edit updates the shared database. Open any other app and your latest property data is already there -- no sync needed.
How the Sidebar Updates
Three things happen every time you change a field. It's seamless and feels instant.
Change a Field
Type a new rent amount, adjust a rate, or select a dropdown. The form detects the change immediately.
Field Saves via AJAX
After the debounce delay, the value saves to the database via a background request. The section badge shows "Saving..." then "Saved".
Sidebar Recalculates
The sidebar recalculates all metrics locally using the same formulas. Purchase summary, NOI, cash flow, and key metrics all update instantly.
