Since you are not negotiating with me or any one here, all responses should give you an indication what the hiring manager may feel. If most people don't care about your financial calculation, the hiring manager may emotionally react the same way.
Negotiating salary is very different from negotiating the price to buy or sell a house. When you negotiate to buy or sell a house, you want the best price, and you try to figure out what the other side will accept. When you negotiate your salary, the future employer is still assessing who you are and whether they want to work with you. Buying a house is an end of a transaction, while hiring a person is the beginning of a partnership.
The future employer wants to invest in you and see that you invest in the opportunity. Too much emphasis on the immediate gain/loss is an indication that you may not be very interested in the opportunity and they may lose you to the highest bidder in the future anyway.
A house negotiation generally ends with a compromise. The buyer and the seller split the price difference. The salary negotiation should end with an excitement for the new opportunity. If you are looking for a compromise, perhaps you don't feel the opportunity is great for you. In that case, you can negotiate for the best price and look for opportunities to jump again.
