16 items on an inspection amendment is not bad. Look at it objectively and determine what you feel is reasonable. When I work with my buyers, we often ask for more than we expect. I tell my buyers we may not get it, but it doesn't hurt to ask. If it's a plumbing issue, bring in your plumber and get a professional opinion. If it's a roof issue, bring in your roofer, etc. If some items are totally unrealistic, then explain that to the buyer's agent in a nice way. Start with determining what the seller is willing to fix, like a creaky door can be fixed with some WD40. Agree to fix things that are a safety concern. That's important. Those things will come up again with the next potential buyer too.
Last month, the inspector for my buyers came up with an 87 page report! We condensed it into 6 pages of what needed to be taken care of and the seller, much to our surprise, agreed to take care of most of it. We wanted the expensive and safety things done, such as plumbing, electrical, HVAC. The inspector also recommended a new roof. We brought out a reputable roofing company to give us an estimate and they said we didn't need a new roof, although he would have loved to sell a new one.
My sellers and I had a buyer last month who asked for the home to be repainted on the inside just because they didn't like the color. We agreed to fix the electrical outlet that needed to be grounded. Pick and choose what is reasonable in cost and time. Ask your broker for assistance on this or you can feel free to contact me. I'd be glad to help you out.
