. 💪 what's this have to do with new construction and development? 

I always check around with other property owners, investors and ask them who they're using for their construction work and if they were pleased with the work. 

Was able to get a meeting with the seller and negotiated using evolving knowledge of construction and deal analysis in addition to discovering seller motivation through direct contact.

Be mindful of the harsh winters and short construction seasons, which can affect project timing.

Are there other options that could be better for a construction to perm loan (not through a traditional bank)???

I think you've forgotten about the concept of Constructive Receipt. 

As mentioned before too, newer construction tends to sell at a premium too. 

The two existing LTR units (on my family’s property) were built 5–8 years ago at a cost of about $80,000 per unit, so I’m estimating a 20% increase in costs for the new builds.My plan is to use the equity in the land as the down payment for the construction loan, which I expect will make closing costs the primary upfront expense.

I've got plenty of experience in both site built and mod construction. 

this is a direct relation to lack of inventory.. new construction on many markets is as robust as its ever been.. we have had spectacular years the last 3 years of course during covid was tough with supply chains but my 500k house I am now selling for 700k and my build cost have gone up by maybe 100k.. so record profits for us..
