My experience has been that when a condo owners association voted to impose a large special assessment they also line up financing for the condo owners who don’t have ready cash (except in NYC coop buildings where the “best” coops require any body purchasing a coop to have $100 million liquid!).  

It also is not liquid, but I have not heard of too many killings over dirt.

...SFR are easier to liquidate.

Pros would be the possibility of a bunch of business from it Cons would be you would be easily identifiable if someone wasn't too fond of you.Probably something I'd consider if I ever got to that point but I'd probably store the vehicle somewhere other than my house.

Department stores will often have a selection in the hardware department as well.

One of the most valuable resources for me diving in was The Book on Rental Property Investing which you can find at https://www.biggerpockets.com/store.

Being that  you are a newbie, good credit and strong liquidity will play a big factor in approval.
