Trying to find my way around the websiteI can see that this site is primarily in the USA.

( I see $3,500 on their site)What else is there after?

I’ve always felt a sense of curiosity whenever I passed a construction site.

I know they can be financed just like a stick built construction loan, however, my credit union is not doing construction loans right now and does not have a time frame for when they will (SECU).I want to use the land as down payment if possible and finance the modular and the site prep for it.Looking at getting a new modular duplex or a SFH. 

I know Fairbanks Alaska was ranked as the #1 place to invest in Air BnBs in the US via Air DNA. 

(often just job site clean up, or hauling boards or drywall around the job site) with the stipulation that the tradesmen would show me the tricks of their trade.

I would go to FEMA's flood map site (https://msc.fema.gov/portal/home) and make sure you are in a flood zone.  

Put it on an auction site starting at your loan balance?
