What you'll accomplish
Right now, running the numbers on a new listing means rebuilding a spreadsheet, or hunting for the last one you used and hoping the formulas still work. DealCheck replaces that spreadsheet with a template built for your exact deal type, rental, BRRRR, or flip, so you can run five properties in the time it used to take to check one. You'll walk out of this setup with an account, your first property analyzed, and a lender-ready report you can generate again for every deal after this one.
What you'll need
Go to dealcheck.io and click Get Started Free in the top right corner. You can sign up with an email address or continue through your browser without installing anything, since DealCheck also runs as a mobile app if you'd rather work from your phone at a showing.
What you should see: A signup form asking for your email and a password, followed by a short prompt to name your first "portfolio" or workspace. Troubleshooting: If the signup button doesn't respond, try a different browser. DealCheck's marketing site loads a lot of tracking scripts that occasionally conflict with strict ad blockers.
Look for the option to add a new property, usually a prominent button on your dashboard. DealCheck lets you search public records and listing data to auto-import the address, list price, estimated value and rent, property taxes, HOA fees, and photos for most US properties, so you rarely have to type in a raw fact sheet by hand.
What you should see: A new property card populated with the address, a thumbnail photo, and basic details pulled from public records. Troubleshooting: If the address doesn't show data, or the numbers look stale, that's normal for off-market or rural properties. Enter the missing fields manually using your own research.
DealCheck builds separate templates for rental, BRRRR, flip, multi-family and commercial, and wholesale deals, since the math for each is genuinely different (a flip cares about ARV and holding costs, a rental cares about long-term cash flow). Choose the template that matches what you're actually planning to do with this property.
What you should see: A set of input sections labeled for financing, closing costs, repair budget, and operating expenses, tailored to the deal type you picked. Troubleshooting: Picked the wrong type? You can typically duplicate the property and run it again under a different analysis type to compare side by side.
This is the step where your own numbers matter more than anything DealCheck imports. Fill in [purchase price], [down payment or financing terms], [closing costs], [rehab budget] if applicable, and [estimated monthly rent] or [expected sale price] depending on the deal type.
What you should see: Metrics updating live as you type, cash flow and cap rate for a rental, or projected profit for a flip. Troubleshooting: If a metric looks wildly off, double check you didn't leave a default value in a field you meant to change. A leftover placeholder interest rate is the most common cause of a nonsensical cash flow number.
Use the built-in comps tool to pull recent sales and comparable rental listings, which helps you sanity check the after-repair value or rent estimate you entered in Step 4. Then set up your investment criteria, minimum cash flow, minimum cap rate, or whatever thresholds matter to your strategy, so DealCheck can flag whether a given deal actually clears your bar.
What you should see: A comps list with addresses, sale prices, and dates, plus a pass/fail or highlighted indicator once your criteria are set. Troubleshooting: Comps data isn't available for every market. If nothing populates, fall back to your own MLS or public-record research for that area.
Once the numbers look right, generate the property report. DealCheck builds a shareable PDF or online report with your analysis, projections, comps, and photos, styled well enough to hand to a lender or a partner without extra formatting work.
What you should see: A formatted report opening in a new tab or downloading as a PDF, ready to attach to an email. Troubleshooting: If your logo doesn't appear, check that you uploaded it under account settings first. Branding options are usually tied to the account, not the individual report.
DealCheck itself doesn't take natural-language prompts. It's a structured calculator, so the "prompts" here are really the exact fields to fill in for common deal types. Keep this list next to your keyboard the first few times you run a deal.

If you want a second opinion on the output, paste your DealCheck summary numbers (not the address or seller details) into GPT-5.6 Sol and ask it to sanity check whether your assumptions look conservative or aggressive relative to typical underwriting for that deal type. Treat the response as a gut check, not a substitute for your own comps.
