I am 20 years old and my parents want me to be an engineer to get a "good salary."  

Buy or inherit and hold all their lives while working the properties for income.I've seen teachers, firemen, software engineers and all sorts of people utilize both strategies successfully.

It'd definitely be more than the $700 to your CPA for an engineered study which could cost $3K-$10K+.

Those estimates are algorithms of comps, but they might aggregate anything 1-2 miles away.

I spend my days working as an Engineering Technician in NW Portland and my nights and weekends renovating my first real estate investment, a 1930 cottage. 

If I'm bringing in a contractor to solve a problem -- need an engineering solution, need to reroute a plumbing line, need to fix a foundation issue, need a kitchen layout along with the cabinet installation, etc. -- then most certainly those are situations where you want to consult with with contractors 1-on-1 to determine not just how much it will cost, but what specifically should be done.But, situations where I want/need a contractor to solve a problem are less common than situations where I already have a specific scope of work, and I'm just hiring the contractor to carry out that scope of work.  

Are they website platforms that allow you to build it out, and sync calendars, and do the pricing based on algorithms (like wheelhouse prices)?

With that, a roof top lease brings many more questions than can be addressed in a forum, access, who has access such as engineer, certified tower maintenance techs, roof maintenance, insurance and liability, loss and recovery requirements........ and this lease will effect market value, consider the liabilities and contingent liabilities of maintenance and access, not just the surface of the roof but the structure below the deck.

I graduated with B.S in Chemical Engineering from University of Houston- Cullen College of Engineering.
