The city informed me that they will not be able to establish a new account in my name until the previous balance is paid off. 

How do you establish Trust here? 

Get all the business goals & objectives laid out then consider establishing a Joint Venture Agreement & a multiple member LLC.  

Each area has its own rules, and we operate within those established rules.I will be more than happy to personally help you in completing the setup of your unit and can answer any other questions or concerns you may have.

What you may want to consider is moving to the area and renting for a bit while you get established(jobs) and then once you have jobs and financing in order you could go house hunting.

I suggest you stay away from the large residential developments in all the local countries, which are always over marketed and hyped to foreigners, though they will include very appealing financing.Better to stay commercial and look at tenanted multi-story retail shop-lots or professional offices in established areas, in my view.

Without knowing how much you have available - you might consider working with an established lender before going out on your own - there are a lot of gotcha's in this business, not nearly as simple as most think of it to be.

So they would have to produce evidence to establish that defense.

It's an interesting field to me and I'm excited to get my feet wet.Outside of this newly established real-estate journey, I work a 3-11 at a Honda engine plant, which provides me with stable income to invest with...especially in this low-cost-of-living area in the Mid-West that I reside in. 

If everything was built correctly than it may just take establishing the use since the ADU is permitted in the zone.
