A friend bought a house designed by some weirdo architect where all of the angles were either 120 or 60 degrees.

I took the advice to put the house in an LLC (or at least try to) from a prominent real estate maven in my area (she has about 40 properties). 

He should be taking care of everything for you, handling materials/subs/architects and everything else for his 20-25% markup.

We bought the lot, had an architect design the building and contracted for the construction.

@Justin R. yes my understanding is a companion unit may be attached or detached...I was more trying to focus on the fact that if these are companion units (attached or detached) that OO is not a requirement.You probably have more practical insight on this as I usually recommend clients don't need my help, and their architect probably is capable for items like this.

Potentially a self-certified architect. 

Material cost wise, you can find $15-25  per linear foot, (plus labor cost) on the lower end if you go through an architect that has connections with local reps. 

You need : building plans with a drafter or architect Fees with cityAnd building costs (material and labor) We have relationships with all of them in our teams Takes between 3 to 6 months for permits and 3 to 5 months for construction (depending on scope of work).

They understood their net worth increase every month even if it doesn’t show up in their checking account.Back in the 1980s and 1990s, principal paydown was considered as cash flow.As syndication has gained more prominence, this concept has been forgotten or ignored.Happy to discuss further.Arn 

@Kolton Weichman, I was the Architect for a 20-Unit new-construction building for Student Rentals which was finishing construction earlier this year.
