At that time, I had 0 money but now I have 5 years of corporate finance experience and savings under my belt to take action on my first deal.

If it matters, the lease is between the tenants and our business name (a fictitious business name, not a registered corp or an LLC), but signed by us. 

You might want to look at getting these assets into a corporation as opposed to holding them personally.

So finance classes, at least in my case, focused on being good at an analysis on stocks, companies, and real focus on corporate banking.

It can be a partnership or a corporation for tax purposes which you set up yourself (must have its own taxpayer ID). 

If I was feeling more ambitious, it allowed me to stop working and focus 100% of my time on writing a book, or maybe getting healthy if I became too burnt out from the usual non-stop adrenaline and cortisol-fueled American corporate work schedule.

It is a trust/pass through entity in which a sponsor (think big real estate investment corporation) buys institutional property (apartments, self storage, commercial, medical office, etc) and then sells interest in the Trust/Property to investors.

Our corporate headquarters are in Pittsburgh and we've done it a ton over here.

Idea is to limit recourse, so if one property gets called, the lender (or other claimaint) recourse is just that property and not your portfolio.LLCs are easy to do once you go thru the first one and most states allow foreign corporations (ie you set up the LLC in WA and buy in OR). 

Corporate housing is interesting - usually higher rents, all inclusive (utilities usually included) and everything paid by a company for longer than normal rental terms. (1 I looked at in NM $1800/mo rent included everything - elec, gas, cable, internet - paid by a hospital for a doctor doing elective surgery for 15 to 18 months at a time plus laundry income.
