Housing hunting on the eastside

Over six years ago I began search for smaller home to downsize to after my spouse's death. Low inventory for several years and most were expensive fixer uppers so I passed. Even these fixers were being gobbled up by international cash payers at way over price, solely for investment purposes - homes remained unoccupied for a long time when I checked back on them in my area.

Quit looking for three years during Covid but now I see smaller homes being bought up and mowed down to insert mega homes with tiny yards (smaller than even the yards we have now!). Removal of large trees and less bare ground I suspect future drainage problems (rain runoff) between neighbors. City MUST get ahead of the upcoming impacts via permits and proper inspections taking into consideration the whole block/area, much like a major apartment complex that is being developed. That is what these homes truly are.

I have now adjusted my home search for housing outside Bellevue and am looking at senior housing - cottage like or larger condo/apartments with a garage (I hope) but am angry that I must leave Bellevue to find it. I want a community feel, with families, parks and resources close by. Need energy efficient construction - Kirkland has a new plan (ParkShore) that will include solar panels, HPs, etc in the design. Bellevue doesn't require any in the new condo/apartments going up --- absolutely ridiculous and short sighted in this era. If I am going to invest time and money into a new home, I want it to be environmentally sustainable. I am willing to install these products but prefer that they are already put in. Where can I find it today in Bellevue?
