Which items I ask home seller to fix after inspection?

Any items that were not disclosed (or unknown) by the seller prior to entering into agreement can be "requested" to get fixed or you can attempt to negotiate the selling price. The seller is not obligated to fix anything nor provide a credit, and if you have an inspection contingency, then it's up to you to proceed either way or walk out of the deal. Most sellers negotiate or repair out of goodwill to get the sale through.

Problem is that when you hit a seller with a laundry list of fix-it demands that include simple and inexpensive to fix things you really are setting your expectations high. I recommend you focus on the safety and functionality of the home - i.e. major issues or safety issues (like the basement handrail, dryer vent, water, moisture, etc) that your inspector discussed with you. They should have given you some priority list and the reason for its priority. If they didn't -- call the inspector because any good inspector should be able to tell you. Then focus on that. Any time there is water damage it should be looked into further because there could be many problems.

You should do one of two things, either ask the Seller to fix them (but there's no guarantee they'll be fixed to your satisfaction) or you could request a credit equal to the amount it would cost to fix all the items. That is a standard type of transaction for a home purchase/sale.

I think the items you mentioned in your first paragraph should definitely be addressed and the squeaky floor should be looked into as far as why, but the other stuff in your second paragraph is comparatively minor (although I hope you mean inside door locks not working, not outside doors).

For example, when I sold my house I actually had it inspected before I sold it so that I would be apprised of any issues. Everything was fine but the Buyer asked for a $500 for a new water heater since the one in the house was fairly old. I wasn't going to quibble over $500 so I did it.

It is a common practice to have a professional inspection done before closing. Check with your realtor to see if one has been scheduled so you can be there and point out the problems you have found.
