Negotiation Advice

[Mitch Bernstein]

Hi All, 

I'm negotiating the price of a lot through the realtors (buyers and sellers agents) and have a tight budget.  

Typically its seems that the offers and counter offers go in rapid succession the same day.  However, from the negotiating tactics I've read about, many say to use time to my advantage, i.e. delay my response.  

Does this apply to lot purchases as well?  In other words, if they counter my offer, should I wait a few days before offering another counter, or is it better to respond the same day?
