My recommendation would be to engage an investment property focused realtor (not a general residential realtor) and let that person guide you through the process from pre-qualification to market/property valuation and selection. 

Buy it personally, and rent it full time to my C-corp?

Unfortunately, this problem waste a lot of my time that could be spent on other investments.I have used the same tax professional for many years and he is very educated, but also much older than me and it's hard for me to understand all the reasons he has expressed why is better to put the rental on my personal tax returns.

I ended up having about 10 abandoned vehicles / RV's (some looked like meth labs...think Breaking Bad).What made you interested in investing in this type of deal?

People want reliability, honesty, being on time, and having a good personality more than just a few $$.

I do not personally use him based soley on the fact that the firm is virtual.

Personally for what people charge for these programs I would say you are 1000x  better off taking some courses at a local college, getting a degree and working in real estate to get paid for experience and then do real estate on the side for your own portfolio as well.

When your LLC takes a loan, expect as members to personally guarantee the debt.

By year 5 we had around 55 people.We did hire a marketing person but frankly marketing wasn't our strong suit. 

Caution:  Personal credit card financing is a huge risk and good luck finding 0 percent interest today.
