Hi Cathy - I'm over in Crested Butte and we have extensive experience in modular. In fact one of our preferred factories has shipped to HI.
In general, the larger the project, the more you'll realize the benefits of modular, especially with custom. How large of a project are you looking at? Are some of the buildings repeatable - ie cottages etc. Repeating a similar floorplan helps.
Construction loans can be trickier for modulars as the lender, who's accustomed to real estate, scratches their head when the factory wants a payment before delivery or before the modules are actually 'real estate'. We can finance the build which we find is ideal for the bank doing the construction loan, they just take us out when the modules arrive onsite thus relieving their headache of how to secure their loan to a non-real estate module sitting in a factory somewhere.
Feel free to message me and I can help you analyze this further. We also have GC's who we work with in other states.
