As the buyer, you will be responsible for many different items. The first is the home inspection.
You will hire a home inspector (click on the guy to the right for my preferred list). This will be paid for at the time of inspection directly to the inspector. You are able to be present during the inspection and ask as many questions as you like and see any issues that may be encountered. The inspector will generate a report that will be shared with both you and me. We will then discuss if there are any items that need to be requested to be fixed. This is another negotiation spot.
The other types of inspections that are optional at your expense include Pest Inspection and Radon.
Once these are completed and all parties agree, the lender will then order the home appraisal. As long as this amount is at or above the amount of the contract, then we will move on to the next steps.
Also, at this point you should have everything in to the Lender so that they can finish up the file and have everything ready for closing.
