I am involved with quite a few mix-use and multi-family projects where historically bank originated construction to permanent financing was used.

If it's appreciation, look to similar properties that have sold recently in that area and consider building a structure other than a tiny home since they don't appreciate like permanent structures.

The person who mentioned theme is correct - The Waterfall House in Palenville does best in Palenville because of their theme.In most towns, non-permanent structures can be used up to 6 months of a year. 

Anyone needing to travel for training or for a PCS (permanant change of station) will need MTRs - often while waiting for their military housing to be ready or to find a house to buy.

More details:I've got the opportunity to buy a multifamily building for $850,000.Rents will be $9,300/mo first year, $10,500 second year (two units need to be finished)$100,000 buildout construction loan built into mortgageCommercial mortgage at 9% first year and 7.5% interest permanent loan, amortized for 20 years with a 5 year balloon.

This tells me that there's a critical supply shortage in these "certain places" and the fix is going to have to be more permanent and not just superficial.apparehently, they are seeing rents go up in "certain places 20, 30, 40, 50% and even higher in some places"

@Mitchell Maginnis first of all there is never a way "around" the laws and regulations, not in any permanency, because it's only a matter of time before one get's caught and most often the penalties exceed any of the "gains" one had received. 

They used to be local to LA, but they have been investing out in SW FL for decades, and moved out there permanently a few years ago, due to the CA investing landscape.

If you need any insights into financing options (value add bridge or permanent), I'm happy to be a resource here to help. 

FYI: If you call an architect or GC and tell them you have this "brilliant never before considered" idea of turning offices into apartments, the architect will eye-roll so hard that they risk permanent blindness.
