That is File vs Proof in one door.
Searching max safe offer calculator Chicago flip usually lands you on a ChicagoLand Appraiser flip toy, a 70% rule form that blanks the rehab cell, or a national profit calculator that still asks you to invent ARV and rehab. Those screens are useful triage. They are not a dated max safe offer tied to sold-rehab comps, Chicago transfer tax, attorney closings, and a Construction cost band toward the finish you named.
Max safe offer is the bid ceiling — not a 70% screen
Max safe offer is the number you actually defend on a Chicago / Chicagoland fix and flip. Classic MAO = (ARV × 0.70) − rehab is a first-pass filter, not a bid. Chicago carry, points, winter slowdowns, and sell costs can erase a thin 70% spread before you list. ARV without a rehab number is a hobby. A Zestimate-shaped ARV minus a group-chat rehab guess is still a hobby.
Here is the File logic in plain words. Mid ARV comes from comps you can defend, ideally sold rehabs that look like your exit. Rehab stays Construction Proof (pending) until a Proof stamp from Banc Construction costs the rehab from subject photos + a sold flip toward that finish. Sell costs, buy-close costs, and hold cost sit in the stack. Margin is not optional: at least $25k or 12% of mid ARV, whichever is higher. Max safe offer is mid ARV minus mid rehab minus those costs minus margin. If the ask is above that line, the verdict is Renegotiate or Pass — not a meeting to talk yourself into red ink. If worst-case profit is red, that is a Pass.
Who this is for: Chicago and Chicagoland investors typing max safe offer calculator Chicago flip; operators who already ran a 70% MAO calculator and still do not know if the flip clears margin after tax and carry; out-of-town capital that already knows ARV and still does not know the ceiling; hard-money desks that want Buy / Renegotiate / Pass on one dated page, not a screenshot of someone else’s spreadsheet. Soft DEMO comps when live data is not used. Construction Proof (photos + sold flip) is not a contractor bid. Returns are not promised. Extra Proof is $129 when you need another stamp in the same month; unused don’t roll.
What this is not: a homes-for-sale page, a foreclosure hub, a promised-return pitch, or a phone-first sales desk. Public phone (708) 901-1805 lives in the footer only. The File is the funnel. Sibling spokes: rehab cost, construction loan packet, buy / renegotiate / pass, target sold rehab. Hub: Proof of ROI.
