You need to learn how and when to use all the tools available to you (financing, insurance, management, etc.)

The key is to find a good fleet manager at a dealership in your area.

Maybe if it was new construction you could pull plans online from permit but highly unlikely.

Sure, about one in 2000 times, by someone experienced enough to recognize a very unusual situation, having the capacity to act on it, having the financial strength, experience and tract record to be able to attract the needed capital, having the knowledge and ability to structure the deal, having the ability to manage and or reposition the property after purchase, and having the capacity to carry the negative cash flow until turning the property around or obtaining lower cost financing.  

I spent most of my life in San Francisco Bay area and, , managed a lot of property there.

Now new HOA management is issuing violations, saying No Commercial Vehicles allowed. 

I have a few construction crews that I regularly work with as well as a Draftsman that helps both with drafting plans as well as managing the permit.

After a few of those I felt comfortable enough to start investing in deals I sourced and managed. 

We have never paid our construction company for services.

I've had a lot of success with Zillow Rental Manager in the past for quality tenants.
