Negotiation
Before bidding always try to understand the seller's need. Do they need to sell
in 15 days or 90 days? Do they need to leaseback, until their new place is ready
to move in? Are they interested in leaving behind some furniture? What items are
specifically not included (curtains, a built-in shelf, ...)?
In a Seller's Market
Here you objective is to write an offer that will be accepted on first try.
Where multiple bids are being presented, it's best to understand the seller's
needs and wants, and present an offer that encompasses their overall objectives,
to the extent you can.
In a Buyer's Market
Here a little back and forth probably won't hurt you, but again you need to
know what the seller really wants and where they are willing to give.
