@Antonio Tapia The insurance estimate that Realtor.com provides for 2-4 units is reasonably accurate for owner occupants.

@Raymond Rashid I would use potential income but also make sure you obtain financial records, copy of the tenant ledgers, copies of the latest bills, copy of tenants leases and others to ensure income and expenses numbers are accurate. 

A survey will be much more detailed and accurate than the County website printout. 

Prepping foundation and structure (beams, foundation, roof etc) between $25k and $50k (ball park) : contractor has to see plans to bid accurately.

However, how accurate is the 'just value'?

that is  good news  regarding the ease  you were able to sell and get full price .....the buyers  seem to be active  in the area in King county ....not much  new inventory so yours  was probably noticed right away...the other element helping stimulate activity is the low interest  rates .......the post above mentioning the lending tightening is definitely  accurate  especially for " jumbo " loans  ( > 741,750  for SFR) ..

This is opportunity to put yourself to the test!

There is also a big difference between condo rent and SFR rent in most areas, so I'm not sure where exactly you're looking but be sure you're comparing as accurately as possible.Los Angeles city rent control is different than the statewide rent control so that is something to consider, also there aren't a ton of reasons you want someone evicted if they are paying the rent and are abiding by the lease. 

Monday I told the realtor & the landlord said get out in 30 days because now I have to have a mild test!

Is this Accurate?
