I'd recommend you really start narrowing down your goals so you can focus on a particular strategy because it's really easy to get distract with all the possibilities.

I was looking back in July but I moved into a new apartment and got distracted.

I hate turnovers, they are a distraction.

I totally made mistakes, primarily because I was distracted with other stuff.  

So if you want you can PM me or we can have that conversation here for others to join in on but I don't want to distract from your main point in your OP too much. 

Don't get me wrong; there are plenty of issues/problems/quirks that old houses have that new houses don't, and an old house can obviously have hidden problems and big repair/maintenance bills too...but, the point is: a brand new house is not a foolproof solution to repairs/maintenance (and in some cases, a brand new house can be a much bigger gamble than an older house).This is a particularly important lesson for inexperienced investors, who tend to be the most prone to "shiny object syndrome" (the tendency to let nice aesthetics distract from real, underlying issues).

Until you start investing and earning cashflow, a PM business is just an added distraction, not likely to add revenue for you and unlikely to be successful in growing clients given your lack of experience.

Luxury buyers and investors are in strong positions, as there will be less market activity to distract lenders, and bankers will have incentive to offer capital to well qualified borrowers. 

Some people want to come here to relax and want to limit the noise and distractions of all the kids, so a higher end community (like Reunion) would be a better fit and get a higher nightly rate. 

There is already a mountain of things you have left to learn and adding variables like 'what will rates do in the next x months' distracts you from the important learnings of how to run rentals successfully.Once you have a few rentals under your belt with stable cash flows and an understanding of what style works for you, sure go take some interest rate risk by getting some variable rate debt.
