Seller Radon Credit Calculator for Johnson County, IA
If you want a cleaner close in Johnson County, budget around $1332 first and keep $1715 in reserve before the buyer starts naming numbers.
Reserve target
$1332
The number to budget before you agree to a credit or repair concession.
No-surprise ceiling
$1715
Use this when the route looks harder, the reading is clearly elevated, or timing risk is real.
Fast-close credit
$1150
A lower-friction number when both sides care more about speed than squeezing the last dollar.
Compromise floor
$650
Keep this in reserve if the conversation moves toward sharing cost instead of full seller coverage.
How to use the local number
Seller repairs before closing
$1332 to $1715
Use this range when the deal depends on the issue being fixed before move-in. The average keeps the ask grounded, while the high end protects you if the contractor flags harder routing.
Closing credit
$1150 to $1332
Best when both sides want a faster close. Start near the quick-close target if speed matters; use the average when you want a stronger but still defensible local number.
Fallback if the seller pushes back
$650
This is not the first number. It is the compromise line to keep the deal moving if the seller refuses full coverage but both sides still want to close.
