In most cases, there are no mandatory fixes after a home inspection. You should request major safety and structural repairs, but the seller doesn’t have to fix them.
There are, however, some repairs that are nonnegotiable because of state regulations or the lender has requested them to approve the loan. These must-fixes will affect the buyer’s situation more than the seller’s.
Some states have nonnegotiable rules on home repairs. Talk with your real estate agent or REALTOR to see if there are state regulations that would give you more leverage when asking for certain repairs.
