In general it is not worth building a single ADU for a variety of issues but the largest is the cost to add the ADU is typically far greater than the value added by the ADU.  

I also saw your post on one of the local Buffalo facebook forums, and will caution you that you are going to get a WIDE variety of feedback from a WIDE variety of investors -- especially on that group! 

how revealing that you don't find it disturbing that:Marco Santarelli was soliciting investors by email and on their internet web site up until June 20th, when Marco Santarelli who signs the email as Founder & CEO, sent out his email suspending payments without previously mentioning any problems.

Like @Matthew Paul we have a variety of vendors and are always looking for more relationships. 

We currently accept rent from tenants using a variety of 3rd party apps-Cashapp, Venmo, Zelle but are moving away from accepting payments in our individual names and want to start accepting payments directly to the LLC/business accounts, but LLC accounts do not accept Zelle and there is a fee for using business accounts on Venmo.

You have provided a variety of situations where doing a cost segregation study would be useful.  

It wasn’t a massive deal—our expected assignment fee was $10,000—but when you’re growing a business, every opportunity matters.Everything seemed to be moving smoothly until the title search revealed a major roadblock: the mortgage discharge couldn’t be cleared because the person who needed to sign off was deceased.

I'm new to real estate investing in general but excited to learn about all the complexities, intricacies, and varieties.

Hi Nida,I'm a bit late to the party but better late than never I guess lolIn the search bar here on Bigger Pockets or even a Google research will reveal a lot of info about certain companies.I'd always like to joke around and say that "Google is your best friend" when looking to work with someone new lolI'd like to second Jason's comment who has been around the turnkey game for a long time and has probably conducted due diligence on many if not all turnkey providers over the years.Not many have stood the test of time and I'm proud to say that we have.Not intending to plug my company as we have many battle scars that started from day 1.But still here and still battling away 🤓Why we survived and thrived unlike many others was keeping our operation small and boutique and only doing deals on our terms.Low volume sales and thorough investor pre-qualification (As not everyone that has a pulse is necessarily a good fit for what we can provide).Some investors did better than others but one thing I can happily say is that we always did our best for all.I believe a very important component to any "true" turnkey company is that the penny ultimately drops must drop with them.Meaning, if you invest and things don't go the way as planned it is entirely up to them to rectify.No finger pointing or passing on the monkey to someone else (Like a realtor, contractor or PM).A true turnkey company stands behind it's properties, rehabs and in-house property management.Key phrase here is "in-house property management".Everything must be under the same roof and the provider must take all responsibility for the outcome of that investment.Wishing you much success
