I'm an engineer and I oversee them installed all the time.

I have a degree in construction management, and my full time job is working as a project engineer for a large general contractor in Seattle.

I have a background in engineering and also residential home repairs, as I am still in business with a family construction company.

I'm a structural engineer by profession committed to finding my first rental property.

I'm an Engineer, and only became a landlord by the lucky move of not selling when we bought a new primary residence.

Recently I got accepted into a college in Toronto, Canada for mechanical engineering and I'm interested in out of state investing.
