Starter prompt

Build a fix-and-flip tracker web app for an investor running four to six rehabs a year. Each project stores the address, stage, purchase price, my after-repair value estimate, the lender’s rehab holdback and monthly holding costs. Split the scope of work into budget lines by trade. Contractors sign in to price the lines I invite them to and upload invoices and photos. Show budget versus actual per line and a bid comparison. Add a draw request that bundles completed lines with their photos and invoices. Calculate projected profit from actual spend plus remaining budget, holding costs and selling costs as a share of the after-repair value.

Build it in Netiva Paste the prompt into a new workspace and adjust it to your business.
Overview

Who this flip tracker is for

Most fix-and-flip investors run a rehab from a spreadsheet, a text thread with the general contractor and a folder of invoices. By week six, nobody can say how much of the kitchen line is spent, which bid covered the roof or what’s left in the lender’s holdback. A flip tracker built with Netiva keeps each house’s scope of work, bids, invoices and draw requests together, so budget versus actual and projected profit reflect today’s numbers instead of the ones you underwrote at closing.

Key features

What your flip tracker can do

  • Budget versus actual by trade

    Each scope of work is a set of budget lines — demo, roofing, electrical, kitchen, soft costs. The spend you enter from each invoice posts against its line, so you see what’s paid, what’s committed and what’s left before a line runs over.

    • Variance against budget plus approved change orders, per line and whole-rehab
    • Committed cost taken from the awarded bid, before invoices arrive
    • Contingency kept as its own line so you see when it’s drawn down
    • Over-budget lines listed first on the project page

  • Contractor bids and sign-in

    You invite a contractor to the lines you want priced and they sign in to bid on them. The comparison puts each bid next to your budget, with the exclusions and earliest start date they noted, so you award work on the same scope.

    • Each contractor sees only the lines you invite them to price
    • Awarding a bid sets the line’s committed cost and declines the others on it
    • Insurance certificates kept with each bid
    • Invoices and progress photos uploaded by the contractor

  • Draw requests and holdback

    When a phase is done, you add the finished lines to a draw and the screen gathers their percent complete, photos, invoices and lien waivers. The draw schedule shows what you’ve requested, what the lender funded and what’s held back.

    • Draw statuses: draft, submitted, inspected, funded
    • Holdback remaining after each funded draw
    • Percent complete per line next to the amount requested
    • An email to the project manager when a draw is marked funded

  • Projected profit that moves with the job

    Every project page recalculates projected profit from your after-repair value, purchase price, spend to date plus remaining budget, holding costs over your planned hold and selling costs figured as a percentage of that value.

    • Today’s projection next to the profit you underwrote
    • Holding costs from a monthly figure and the planned hold
    • Every figure labeled as an estimate
    • A projects board sorted by projected margin

How it works

From prompt to a live flip tracker

  1. Describe how you run a rehab

    Tell Netiva how many flips you carry at once, which trades you budget for and how your lender releases rehab funds. The agent drafts collections for projects, budget lines, bids and draws.

  2. Load your active projects

    Add current houses in the collection grid, then ask the collection assistant to draft budget lines from your scope-of-work notes so you can review them before anyone bids.

  3. Test the numbers in the preview

    Open a project in the live preview and check budget versus actual, the bid comparison and the profit projection. Annotate anything that looks wrong and the agent updates it.

  4. Publish and invite contractors

    Publish in one click and send contractors the sign-in link for bids and invoices. Every change is checkpointed, so a profit formula edit you regret is easy to roll back.

Examples

Ways teams use it

  • A solo investor with a rehab loan

    One investor carries two houses at a time on a loan that funds the renovation in draws. The holdback balance and the draw packet sit on each project page, so the next request is ready when a phase wraps up.

  • Partners splitting money and management

    The capital partner follows the projects board while the operating partner awards bids and logs spend. Both see the same projected profit, and the Monday email flags any line that’s running over.

  • A team flipping in two markets

    With 12 or more rehabs a year, the team saves filtered views per market and per project manager, and reads the sold recaps to see which trades ran over most often before pricing the next scope.

Good to know

Before you build

  • Profit projections are estimates

    Projected profit is only as reliable as the after-repair value, holding costs and selling-cost percentage you enter. The app does the arithmetic; it doesn’t appraise the house or give lending or investment advice.

  • Your loan agreement sets the draw rules

    Holdback amounts, draw inspections, fees and the documents each draw needs come from your lender. Model the draw packet on their checklist and submit it however they require.

  • Lead-safe rules for pre-1978 houses

    EPA’s Renovation, Repair and Painting Rule covers buying, renovating and selling pre-1978 homes: paint disturbance past six square feet in a room or 20 outside, plus any window replacement or demolition, needs an EPA- or state-certified firm. Sellers owe buyers lead disclosures.

  • Lien waivers and permits vary by location

    Waiver forms and the permits a job needs depend on your state and city. The app keeps the waivers you collect with each draw, but it doesn’t check whether a form or permit meets local rules.

Compliance note

Projected profit, holding costs and after-repair values in a flip tracker are estimates calculated from the numbers you enter — not an appraisal and not financial, lending or investment advice. If the app shares project pages or draw packets with partners or lenders, label those figures as estimates on the page.

FAQ

Questions about building a flip tracker

Can contractors bid and send invoices through the flip tracker?

Yes. You invite a contractor to the lines you want priced, and when they sign in they see only those lines and their own bids. They enter a price with any exclusions and an earliest start date, then upload invoices and progress photos once the work is underway. Awarding a bid sets that line’s committed cost and marks the other bids on the line declined.

How does the app work out projected profit on a flip?

You describe the formula to the agent. A common version starts with your after-repair value, then subtracts the purchase price, spend to date plus the unspent budget on each line, monthly holding costs times your planned hold, and selling costs taken as a percentage of the after-repair value for commission and closing. Soft costs such as loan points sit in the budget as their own lines. Every result is an estimate from your inputs, and the page says so.

Can it put together a draw request for my rehab lender?

It can assemble the packet: you add the lines finished since the last draw, and it carries their percent complete, progress photos, invoices and signed lien waivers with the amount requested. You then send it the way your lender asks — through their portal, by email or on a form they supply. Once the lender funds it, you record the amount and date, and the holdback remaining updates on the project page.

Will the flip tracker tell me what to offer on a house?

No — it’s built for the job after you buy. It stores the purchase price and after-repair value you settled on, plus the profit you underwrote, then tracks the rehab against them. Comparable sales, a buy box and maximum-offer math belong in a deal analyzer, which you can build in Netiva as a separate web app.

How do I handle a change order from my general contractor?

Put it on the line it belongs to. Rotted subfloor found under the tile goes in as approved changes on the flooring line, so variance compares spend with the budget plus the increase you approved, and the line stops reading as an overrun. Anything you haven’t approved yet stays off the line, and the contingency line shows how much room you have left.

If I change the profit formula and get it wrong, can I undo it?

Yes. Every change the agent makes is checkpointed, so you can compare versions and roll back to the formula you had before. The app is clean, framework-standard code that you own and can export whenever you want, and you can keep chatting with the agent or annotate the preview to adjust how the numbers display.
