Most architects and major underwriters I've spoken to consider the "plans" that were flashed before the public to be impossible.

On a personal note: I am not a realtor, have never taken the licensing course but I buy real estate with the help of a power team: realtor, appraiser, home inspector, legal professional, contractor, architect, mortgage broker (moi)...you get the idea. 

We hire architects for all of our projects.

Yes, we used a local architect who has designed several homes in the neighborhood, including our next few projects.

Home inspector and architect found the roof in need of replacement but the walls and foundation structurally sound.

Hey everybody, I am very happy to post my first project that starts since I join biggerpockets 3 months or so ago, I moved to San Diego 18 months ago, I used to be in the big private equity sector, but I decided to start investing and consulting, so 6 months ago this  young talented architect came to me with the idea that his Girlfriend family, owned some land/Shack in Hillcrest area in San Diego, so I saw the property and fell  in love with it so I started consulting him as how to get funding, ETC. so finally after 6 months with city planners, and shifting as 30% equity investor my self, we found a bigger equity partner for the remaining 70%  and I am happy to share. that we started construction last Thursday this is a render of how our new 9 units are going to look like. 

Attorneys, accountants, architects, consultants, contractors, niche services and retailers, ... 

A custom home builder, an architect, a developer, flipper, rentals?

Dear Duarte,  I am an architect and real estate consultant based in Lisbon.

2) Do I need an architect to draw up the plans for my basement or will drawings I do myself suffice?
