However, I dislike that it's growing so much that it's attracting a bunch of panhandlers...and litter...and roadside memorials.

I have talked to some zoning and building folks who say yes no problem with modulars "as long as it meets code" but then I read the code carefully and they have carefully crafted it so that modular construction can't meet it.In one case it was the eve overhang required as well as the pitch of the roof.Zoning for townhouses means within City limits which means City building officials.

I know if I were in the this resident's shoes I wouldn't want to live in the home any more due to the horrific memory.

I am an avid architectural history buff with focus on the Arts and Crafts period from the early 20th century.

Memories are short for most. 

I'm going of memory here, and that can't always be trusted haha 

Just do it and dump the memory.

My taxes went up last year on my residence by an extra $2000 (property value went up by over $100K, from memory - about 33%).

Rather than facilitate all plan investments, the IRA is simply used to purchase the ownership interest of a specially crafted LLC.  

Meanwhile I pay people to learn my craft and still striggle to get workers lol. we live in a great age where information is easy to find online.
