I have found that sellers with certain brokers are more negotiable than others.
Also, one broker I almost got into an argument with because he didn't want to present my 'low' offer. Wanted me to send a 10% EMD check before he even contacted the seller. Ridiculous. Funny thing was my offer ended up being accepted and the brokers way of apologizing was telling me I got a great deal.
I made an offer on one contract, and the broker responded that the seller had just turned down a higher offer with the same terms. I offered a few $/point less and seller pay closing, but they had just turned down an asking-price offer with seller paying closing. So, they didn't bother to present my offer.I was told under Florida law they have to present all offers
