@Thomas Lin congrats on getting started. Orlando is a great place to invest, we've enjoyed over a decade of appreciation, mostly double digits! So building equity should be easy especially if you get a property that you can add value to.
As far as neighborhoods, that would be a conversation with you on what risks you want to tolerate. Think school scores, employers, average income, families vs young professionals etc. Most investors want a great deal, but realized most of them are in areas that they won't invest in.
One idea to consider would be new construction, builders are offering pretty good incentives on quick move in homes. You will have equity built in by price increases that the builder forces, a brand new home with warranty (no cap ex) and be able to justify higher rents due to it being new. You lose the value add aspect, but have far less worries.
Happy to have a call and go over some ideas with you.
Best of luck!
