One of the things you can do is reach out to a few banks/lenders and have them add you to their list of "Approved Builders" just make sure you have the time and crew because it can get busy fast.

Commercial real estate solutions for developers, home builders.

"Regentrification" to me is when a City, Mayor's Devenlopment Council, offers Tax breaks etc. for Builders to build "affordable housing" in the run down neighborhoods where I would never want to own anything.

I target realtors who have new construction listings and also target new home builders as end buyers.

Maybe some specialty programs exist for prefab homes or a custom ADU builder might have his own lender partner they could refer you to... but unless you yourself are an experienced home builder with a track record in ground-up construction, you're basically looking at a hard money or a HELOC.

I assume that it may also be cost effective to go with a builders templated design as the design docs have been completed and approved by city?

Lots of issues from taking too long with builder and permits and loosing funding to bad info from property manager about my STR.

Does anyone have experience with modular home builders, buying plots of land, or new construction?

One avenue while you are waiting for that license is, getting a workman's comp (you could revise the principal's name later if you wish), and hiring him as piecework job, this would fall under Owner-Builder, this is only legal if 1.

I am looking for a builder to partner with who will finance building costs (and get reasonable GC fees above cost for their efforts as well).
