How much should I spend prepping my house before selling?

Prepping budgets vary by house, because the right amount to spend depends on which condition issues are actually suppressing offers versus which are just cosmetic preferences.

Skipping that walkthrough is how sellers end up over-improving a house for a market that does not reward it. Joel Boss will tell you honestly which items are worth the money.
