Seattle/Tacoma purchase price offer

[James Tarleton]

Hello, in the PNW, the market is booming! I'm wondering, when you first make an offer on a home, how much more or less are you offering on the purchase price? Especially On hot deals that are on the market that you can assume have multiple offers. Especially on homes in the Tacoma area. I was wondering because I have been watching a couple homes in the 300k range (which is the medium price in Tacoma area) and I wanted to measure how much more I should offer, where My offer won't be over looked. I know you have to take into consideration, factors like how long it's been on the market, area, CMA, etc.

suggestions anyone?
