I would day depends. Sometimes if you pay $500 and it will lower your interest rate by 0.125% or even 0.25% than if you don't pay any cost. which one would you choose? If you are talking about full closing cost, then forget about it in the currrent market. If you are doing re-finance, you can use refinace plus and don't need to pay loan insurance. If you are doing purchase, you can either do two loans or you have to pay PMI if downpay is less than 20%.
You have the assumption that market will be the same or better after 4 months. If you think rate will keep the same or get better, then do no closing cost is the best option. If rate could get worse, then pay some fee may not be a bad idea to get a better rate. And you will do re-finance with the same broker, otherwise you need to wait for 6 months.
