But if I decide to pay an extra $2,000 per month, in addition to my (dropping month after month) minimum interest-only payment, when the loan is recast to principal and interest, the new payment will be based on the remaining balance ($396,000) spread over 25 years.

An umbrella policy for additional liability. 

Reflecting on the last 20+ yrs, when we could cash flow immediately with low cost sfr, had we gone with the higher priced properties and significantly lower cash flow, more debt, we could not have achieved IRRs even close to what the lower end product has delivered, nor paid off the investments. 

Additionally, the supply of homes for sale is constrained because of this and will be for some time putting upward pressure on prices in most markets.Thinking about renting your house in Seattle would be wise as someone else will pay the mortgage down, and rents and the value of the property will go up over time.

That would be a helpful addition to your plan as you would further reduce your cost of living.Also don’t forget from that $600 you are planning on getting in cash flow you have taxes, insurance, maintenance, capex, and vacancy to consider.With two homes, you may want to keep that extra $20k as an emergency fund rather than spending it on a third property and then be left with no emergency funds.

We have classes in addition that we offer. 

A clean, neutral-looking curb gives prospective homebuyers a chance to visualize their own additions/upgrades.

So you have some great resources right off the bat, my additional Referrals would be too many :)
