Hey Ivy! I appreciate your input! I'll answer these questions to the best of my ability.
1) We offered $456k to get the seller to remove the shed before closing, otherwise I was going to offer the asking price and deal with the shed later. I felt the headache of dealing with that would have been more appropriately wrapped into the loan, so that's the route I took.
2) The market is incredibly hot, but the high appreciation rate (149%) is due to the US Navy closing down a base in Hawaii and relocating the assets to NAS Whidbey Island (30 minutes south of this location), with more future plans to expand the amount of squadrons on that Naval Air Station.
3) Yeah, renting the one bedroom out for $2000 is unattainable. I am planning on splitting the mortgage to househack until I get a new duty station, and then be able to rent out the two bedrooms for at least $2000/month hopefully. I apologize for the confusion on that.
4) I am going with the 0% down, but will be using my Basic Allowance for Housing to cover my half of the mortgage (splitting it in half with another roommate), setting aside ~$1500/month, and once the roommate moves out, I will increase that up to ~$2500/month.
