I am considering putting them under a property manager. 

I live in California, and bought a tax lien certificate (technically a Certificate of Purchase) on vacant commercial land in Arizona, sight unseen, at an online auction.

I recently purchase a mix use Property where I will have residents and commercial tenants and my insurance wont insure the property will love some contacts for insurance that insure this type of properties 

Hi, I'm hitting the sweet spot regarding my property management company. 

Most of that here will go into the downpayment and closing costs and even then, especially if you long-term rent out the property, you'll likely not cash flow much at all even if you self-manage.  

While insurance has covered some costs, the process has been stressful, even with a property manager (their responsiveness to these issues has been slow).

We have 2 LLC's that run management companies and 10 LLC's that do real estate investing.

In fact, we ended up paying a bookkeeper $450/month plus the $90 subscription to QB online to manage our relatively small portfolio.

I managed a budies house in a strict HOA and he was continuously being sent bills for fines from things like parking on street or leaving trash cans on the street after trash day.I personally will never buy an investment property where there is an HOA.

Both properties are under property managers.
