Steve - Up front disclaimer: all septic system issues are site condition and regulatory jurisdiction specific and I have very little information to go on - that being stated ...

Second side note-when it comes to STRs you have to know if your city/county/state/ whatever regulatory body will allow you to have a permit with ownership being in an LLC. 

Unless the setback, lot coverage, floor area ratios, parking requirements were also changed, these new laws are meaningless for majority of urban properties. 

Plus with a 6,500 square foot lot, the set backs could make it difficult to build something decent.3.

.#2   If that doesn't work...Maybe file a BBB complaint or better yet with the regulatory authority for real estate brokerages in VA. 

Building a DADU does not require subdividing the lot, and as Seattle DADU rules are incredibly generous ( 3200 sq ft minimum lot size, typically less than 35% lot coverage, 5 ft setbacks unless there is alley access, then 0 lot line ), a lot of lots in Seattle are well positioned for DADU's.

This could change though depending on my childen's lives (special needs, major accident/setback, etc...)I agree that the the knowledge is way more important that the wealth.  

Walmart and even the used car industry has stricter regulatory and moral guidelines than many in the Wholesaling industry possess.  

Some bulk mail users dont want to spend the time peeling stamps so they pay a little more and use metered or print on stamps...I always use the peel and stick...Only set back is the 500 roll you have to tear each stamp and lick them your elf...All the other rolls 3000, or 10,000 you can just peel off...I buy the roll of 10,000 usually.
