My only complaint is communication, it can be difficult to get answers from office staff.

I would talk to a title officer unless of course your an attorney state then talk to another attorney who can look up case law.That's exactly what I recommended to the family. 

I liked my conversation with Realty One Group (Corona office) and wondered if anyone had any recent experience with that group that they could share.

Get their commanding officer and they will have them make it right.  3.  

You will need a licensed TX attorney to oversee the legal documents, you need escrow officers and transaction managers and business development/marketing.

As far as my personal investments, I have mainly focused on multifamily - but I do have commercial retail and office investments.

Reach out to the Marcus & Millichap offices in Columbus/Cleveland and have one of the MMCC commercial mortgage brokers produce a few quotes for you.If you don't have the time to research contact info / programs for 25-50 different lenders and make the calls/emails necessary to obtain optimal financing, hire a broker.

And is mileage looking for additional rentals and flips in markets you currently own properties in, deductible, if you operate out of your home office? 

I own a commercial building where I use half of the building for my team and the other half is office spaces rented to businesses.

They said it is usually faster but someone that handles it was out of the office.
