A Buyers Agent is paid by commission from the sale of the home, and should be FREE to you. They will guide you through this situation.
The "BUY AS IS" means the seller is not going to give you a credit or repair any of the issues of the home inspection. If you had the home inspection done and it came back with more issues than you want to tackle, then YOU do not "pass" the home inspection and sign off on it.
Just because a property is being offer "as is" it does not mean you should not know what "as is" is. The home inspection should be done regardless of whether the seller will credit the buyer for repairs to let the buyer know what they are buying.
