Looking for some recommendations for an attorney for drawing up a contract between us and someone to advise us on the best way to structure taxes, form an entity if need be and etc.

So less out whatever I'd get back on that on taxes, but then add in mortgage interest and property expenses, suddenly it's significantly cheaper for me to rent.

A 20% down payment would be a bit to steep for me, especially if the next deal I am planning to do would be a 4 unit or up in the Atlanta area where the prices range from 300k to 500k.

You can even get a mortgage on NNN leases as they are recognized as one form of real estate ownership. 

Does anyone use any form of 3d measurement devices to take measurements that can then be uploaded into a design software?

Regardless of what form of financing you plan to use, you must qualify at the BoC posted rate for a 5-yr fixed term @ 25-yr amortization.That said BRRRR is much older than Josh and Brandon's catchy acronym and works just fine here in Canada.  

As such I can pull comparables from our local MLS on local investments and as a member of National Association of Realtors I have access to their RPR product that pulls comps for me nationwide.

Like full time job for 2 years, credit, form of income etc...  

What advice does everyone have for me on my first JV deal?

If I could do it again I would have loaned the money at 8-12% and looked for a real deal.Best of luck and have a Guinness for me!
