Also, be sure to notify your insurance company that while you are still living on the property, you also have tenants. 

The market has been growing in terms of population, jobs and, major companies moving here like Intel, Google, Meta, etc. 

Have you considered using a property management company?

If you are new and don't have a clue, then I would certainly recommend them or some company that can guide you through things until you have an understanding. 

.: Quote from @Audrey Sommer: A couple weeks ago, I was talking to a texan resident that came up to Washington State to help the company I work at, train our team for a new product launch.

We're also seeking to buy a local (Raleigh / Durham) property management company to expand that business more rapidly.

Does anyone have any experience (or know someone or a company that might) be able to demo a concrete staircase Ana turn it into a driveway and ADU ramp ?

If you're not conducting the work yourself, contract with reputable and competent companies.

About 5 years ago one of the sellers we bought a multi family from told us about a company that has a lot of landlords like us and we coshare insurance coverage.

OPIf you have a company with a Sales tax license.
