@Daniel ScullenThe C-Corp generally makes sense if other investors (shareholders) will also invest in the C-corp because it will afford them limited liability. 

Also, saying that you need to get the concrete done anyway and don't have that kind of cash on hand leads me to believe you might want to think about getting some stronger cash reserves or your own lines of financing before proceeding; I've got credit cards with credit limits double that, where I could self-finance those kinds of repairs if necessary, but that's not a big enough hit that I'd have to worry about taking out loans on paid-for houses. 

however don't limit yourself...   

So I try to limit any cleaning demands from guests. 

I have very limited real estate experience but I do have some friends/ family that invest in real estate.

The sky's the limit if you apply yourself.

Question 2: what are the limitations if any, regarding the price of the second home purchase?

Landlords are allowed to set their own occupancy limits.

Based on my limited searching, rent values are only about 20% less in those areas and properties are probably 50% cheaper.
