That is unethical, dishonest, and may harm a seller.

Agents have a habit of "forgetting" to take pics of everything.

You need to check your lease and relevant state statutes and case law on the matter but typically in a situation where the home is still habitable you would reduce tenants rent by the reduction in value of the property, which is likely substantial when going from 3br/2ba to 2br/1ba.

There are several reasons for that,   summed up they are:1)  the duplex is the oldest property (pre-1900) and while well maintained,   is economically and functionally obsolete2)  Located on L2 zoned land  (4 townhouses,   small apartment/ SEDU complex, etc) would be allowed on lot.3)  I was ready to end house hacking,  I had lived in one unit of the duplex since purchase4)  Lower unit (one I owner occupied) not habitable per Seattle rental inspection ordinance.   

I will continue to take the meager match my employer gives (25% match of 6% of salarty), but I don't see the harm in cashing out the 22k from the old Roth 401k and then start over with my new employer and deploy that 22k into cash flow producing assets. 

I don't know how you're finding buyers but also without being too mystic, if you approach a buyer with some information on their specific buying habits (i.e area, price range, home type), they're far more likely to entertain a conversation past 10 seconds and many times you'll leave with an email/number.

Am I harming you or offending you?

No harm no foul?
