What are some of the key factors to know and understand?

Read your state regs, - involve your area authorities (fire marshall, building inspectors and anyone at the state level of whichever arm of state govt manages Assisted Living/Nursing homes early and often in the design/build process - they have to be kept in the loop and part of the process to keep happy and so that your facility can be auth'd and up and running)Best of luck

I know it depends on so many factors.

Some factors to consider in Daytona or anywhere close to the Coast is Insurance..

Credit score is an important factor but no the only one..

This would be a conflict of interest for sure but it depends on how the scope/design is contracted.

This doesn't even consider the overhang on the trailer from the rear axle to the back of the RV, so there is a tail swing factor when backing into or pulling out of these units. 

Hi Rolf - The costs will vary depending on the design of the building among a variety of other factors.

Attempt to transition to a new job as quickly as possible though possibly having to dip into my Roth IRA, but hopefully still having the option of taking out a mortgage once I secure a new job being that my credit score and other factors are strong. 

Once again cash flow, ARV and other factors must be good though.
