Use Navikoo's rehab cost estimator to build a structured renovation budget before you commit to a property. Organize exterior and interior work by category, estimate project costs, update the scope as contractor pricing becomes available, and save a detailed rehab report.
Renovation assumptions can materially change the projected economics of a fix and flip, BRRRR, or rental property. A structured rehab estimate helps investors identify the work they expect, organize costs by category, and update the budget as better pricing becomes available. Instead of one rough number carried through the whole analysis, you get an organized estimate you can compare across projects and revise as due diligence progresses.
Enter costs category by category, then review a clean breakdown and total. Here is what a typical report looks like:
The Rehab Estimator helps you organize your rehab scope clearly, estimate costs before you commit to a deal, and replace rough guesswork with a structured budget. Whether you are planning a fix and flip or getting a rental rent ready, you can see exactly where the money goes.
Every estimate can be saved to your Saved Analysis, so you can reload it later, refine the numbers as you get contractor bids, and compare rehab costs across different properties.
A useful estimate is less about precision on day one and more about having a scope you can revise. Working through these five steps in a real estate rehab calculator gives you a number that improves as the deal progresses rather than one you quietly stop trusting.
Walk the property and identify expected repairs, replacements, upgrades, and deferred maintenance. What you write down here sets the boundary for everything that follows.
Separate exterior and interior work, then group items into logical categories such as roof, exterior, demolition, flooring, electrical, plumbing, HVAC, kitchen, bathrooms, paint, and any other applicable work. Categories are what make a house rehab cost calculator reviewable later - a single lump sum tells you nothing about where the money went.
Use available quotes, pricing from prior projects, local knowledge, or preliminary assumptions appropriate to the project. Navikoo organizes and totals the figures you enter; it does not look up contractor pricing for your market.
Where appropriate, include a contingency rather than assuming every cost will match the first estimate. Unexpected conditions can become visible during demolition, inspection, or due diligence, so a contingency can help account for uncertainty when appropriate.
Replace preliminary assumptions with contractor bids, inspection findings, or confirmed pricing as due diligence progresses. An estimate built to be revised is more useful than one defended after the fact.
The scope varies by property, and no project needs every item below. These are common categories an investor may review when using a rehab cost estimator for investors so the expected work can be organized before the budget is finalized.
Once you have a preliminary rehab number, carry it into the Fix & Flip Calculator or the BRRRR Calculator to see how the renovation assumption affects the full deal.
These are two different documents that get confused because they produce a similar-looking number. A rehab cost estimate is useful for preliminary underwriting and for organizing an expected scope - it is your working assumption about what the project involves and what it is likely to cost.
A contractor bid is a project-specific proposal based on that contractor's own review of the property, their pricing, their labor and materials, their timing, and their terms. It is an offer to do defined work for a defined amount, and it is the document you actually transact against.
Navikoo's rehab cost estimator helps organize assumptions. It does not replace property inspections, contractor evaluation, engineering or structural advice where that is needed, local permit and code requirements, or formal project bids. Treat the estimate as the number you use to decide whether a property is worth pursuing, and the bids as the numbers you use to decide whether to proceed.
