I still ride bikes and I’ve severely limited my carbs and sugar after the suggestion of the Bigger Pockets member mentioning it. 

I recently read a book that mentioned there being a lot of power and benefits of a personal corporation but I'm curious as to when a corporation is actually beneficial over the latter. 

If it is a class C office building with 10% occupancy that is very different than a Class A MF which is still very different than a debt fund with zero leverage.As mentioned risk and return go together  - greater risk should have greater upside

At your age as Bruce mentioned I won't recommend a condo for the things he highlighted.FHA most likely won't approve them, but there are loan programs that works similarly than FHA that will.

I only wanted to clarify that almost everyone who mentions their equity means “cash after paying off their loan”, not their gain.

(b) Is it okay to talk to multiple realtors at the same time (I'm thinking it would be better to have a separate realtor with lots of market knowledge and experience in each of the mentioned locations) or should I only plan to use one?

In my day job I do SEO for a digital marketing agency and I am more than happy to talk SEO with anyone who has questions.I'm interested in Long-term rentals, though admittedly, finding deals below market value and funding those deals (not to mention I honestly have no idea have to put the deals under contract in the first place), are problem the first things I'll need to learn.

as mentioned the most common way is you do a cash out refinance to buy an ex out of a property.

You mentioned buying a MTR condo.Is your income below $150,000 or are you able to claim real estate professional status?

The ones you mentioned above?)
