If you don't look at them before buying in person, you will get burned at some point and regret it.   

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.

The key is to identify personal property from real property.

Or a personal loan if interest rates aren't cost prohibitive?

Conducted personal research.

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.

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

If you're more of a 'personal referral' person than a 'do research online' person, and this is local to you in Manhattan, KS, hit up one or two of the trades people in the "little apple all stars" BNI group.

I personally would never invest somewhere that could outlaw rentals.

I have a situation where a person I know is moving out of the country and would be looking to put their home for sale in the summer.
