(So far, I have the tax-assessed value, zoning code, and lot size.)Are there any red flags I should watch for when it comes to selling infill lots in urban/suburban areas like Portsmouth?

This is a nice urban area with tree lined streets and very close to the CA capitol and several hospitals. 

If you are interested in building and development, I recommend joining the Urban Land Institute, a professional organization dedicated to urban development.

👋 I’m Ali — real estate agent here in Boston.I come from a background in urban planning and design, which has really shaped the way I think about neighborhoods, housing, and long-term investment.

By allowing more units on a single lot, cities can accommodate more residents without needing to expand their urban footprint.

Hey, same question here - I'm looking at sober housing and 3/4 housing for people re-entering society after justice system involvement.  

Quote from @Tim Cornwell: @Jay HinrichsI don't think HB1110 is the ultimate solution to all our housing problems, but it feels like it will allow for some additional housing and infill to occur where it wasn't allowed previously. agreed some housing but reality is quite different than what urban planning nirvana envisions.

I felt like I was contributing to society in a new way by becoming a housing provider.The first tenants weren’t perfect, but things were manageable… until they stopped paying rent and ghosted me completely.

That’s why you see more success stories in the Southeast, Midwest, or tertiary markets — not urban cores of high-cost states.Some developers are experimenting with modular or manufactured housing to bring costs down, but even then, zoning and land prices remain the gating factors.Until land, policy, and entitlement timelines shift, “affordable” new construction in expensive markets is a tough ask without subsidy. 

Those of financial capacity have been in a mass migration from inner too outer urban/suburban areas.
