This unit was gutted down to the studs so there is all new electrical, plumbing, windows, sheetrock and finishes.

Being out of state, I would suggest vetting your "team", meaning find an investor realtor, lender/s (hard $ / long term), property manager, contractors, etc.

Even large and small businesses with intangible residual services like TV, internet, security, pest control or the local contractor with remodels in process could fall behind on payments revenue contract. 

The property does have heated radiators through out each unit. everything is separated for each unit electricity, gas, and window units in each property.

It's a big money maker for architects, engineers, and contractors, but not a huge opportunity for investors, nor should it be. 

Your clients should focus on properties with significant equity potential and work with experienced contractors to stay within budget and timeline—especially with borrowed funds on the line.Avoiding Bad Deals - Encourage them to work with experienced agents, contractors, or mentors and always run multiple scenarios, including worst-case outcomes, to stress-test their numbers.Reserves - Advise your clients to keep a reserve fund separate from their loan for emergencies, unexpected expenses, or delays.

I didn't know at the time of purchase, but it can be a deal breaker (from what I've been told by several contractors) on putting up recessed lighting.

Expect a custom ADU to take 9–18 months, with 3–6 months for design and permitting and 6–12 months for construction, depending on complexity and contractor availability, and the speed of processing permits.

For example, it's difficult to appease a situation if 1 tenant claims they're using less electric/gas than another.
