Ultimately, I'd like to retire from my current job in 2-3 years and do investing full time. 

But how do I get financed once I quit my job and invest full time. 

If it is to you, they now have an express payment option that costs $2.99 and shortens the length of time to get the money in your account. 

I understand you have to pay in full by Cashier's checks.

One of the things that should also be noted is that millenials tend to favor public transportation, ridesharing, & cycling to get to their destination.

Don't underestimate a house full of "stuff".

I think it is a great idea to present a couple of different options to sellers, one of which could include offering a few thousand dollars down and pay the remainder of the purchase price over time, with agreed-upon terms like length of loan, interest rate, amortization, balloon payments (if necessary).

It's a large complex so they have a lot of public info on their HOA website.
