Investment property deal improvement workspace
Improve the deal before your money is at risk.
DulyCheck finds weak assumptions, explains why they matter, shows ways to improve the deal, helps turn assumptions into evidence and recalculates the numbers as the property changes.
Start free with 1 new property each month and 3 AI document reads. Investor is $5/month for 10 new properties and Pro is $10/month for 50. Once a property is in My Deals, revisions, evidence updates, recalculations and what-if scenarios for that property stay free. Optional human review is $199, or $298 total when you choose an available priority day at checkout. DulyCheck does not tell you to buy or sell.

Verify Monthly rent
Signed lease, rent roll, or three closed rental comps.
One property workspace from first assumption to better-supported deal.
Find the weak points
DulyCheck ranks the lines where weak proof and financial exposure collide, so you know which beliefs deserve the hardest look.
Improve the economics
Test rent, price, financing and operating assumptions without paying again every time the deal changes.
Turn belief into evidence
Missing, Assumed, Estimated, Supported and Documented stay explicit so you can see which inputs are getting stronger.
Work the next action
The workspace turns risks into an action plan, keeps diligence progress with the property and points you toward location-aware Local Help when useful.
Simple plans
Pay for new property flow, not every revision.
Existing property workspaces keep their history. Revisions, evidence upgrades and scenario testing stay free for the same property.

Optional human second opinion
Before you put real money at risk, get Brandon's second opinion.
The software can challenge the model. Brandon Foster reviews the saved deal like an experienced owner and investor who has to live with the outcome after closing: which assumption deserves distrust, what needs proof, what could become expensive later, and where price, credits, financing or diligence could materially improve your position.
It is not another automated score. It is a written second set of eyes on your exact property, including what Brandon would be comfortable with, what would make him pause and what he would verify next.
Brandon's standard review
$199
Written second opinion within 3 business days, attached to the saved deal.
Brandon's priority review
$298 total
$199 review + $99 priority. Choose an available earlier business day and pay once. If you already bought standard, you can still add priority later for $99 while capacity remains.
