$34,000 net cost of lot: $10,000 worth of paid permitting and impact fees that are transferrable to the new owner and $10,000 worth of seasoned dirt fill on the lot. ($54,000 -$20,000 = $34,000). So many of the hassles have been completed, so build your dream house sooner than you thought. Great location as it is in walking distance to Mariner HS and middle school and close to the NW Softball Complex. Great area for families and retirees alike.
