Correction to my response it should read: You can not do repairs before closing because you don't own the house until you close on it. Good Luck

Typically it is the seller's responsibility to have these issues fixed by the close date or if he doesn't want to do repairs an estimate for repairs needs to issued and in lieu of repairs the buyer receives that amount at closing. The repair amount in lieu of actuall repairs usually is applied to the buyers closing cost. Do you have a Realtor or propose this to the seller. You really can have these repaired by your electrician prior to closing because you do not own the house as of yet. Good Lucj
