No. Homeowners appealing their own home can file themselves, for free, on the county's website, and it's easy: every Morganwell report includes a step-by-step filing guide. Morganwell is not a law firm; we build the evidence and guide you, and you file it in your own name.
The check is free. While we launch Palatine, every full packet is $50 flat, one time. Never a share of your savings. Filing with the county is free. No outcome is guaranteed.
Filing is the county's process and it's free. Morganwell is the evidence: we read the county's own records and show whether comparable homes are assessed lower than yours, in the form the county asks for, plus a step-by-step guide so filing it yourself is easy.
Ten seconds to check. Five minutes to file. Then you wait for the letter.
