Welcome to Orlando!
I'm visual so I'll try and describe the area in sections. If you put Bay Lake/ MK at the center of a big circle then draw an X through it you'll see four pie shaped quadrants.
North is Windermere and Winter Garden (sometimes referred to as Horizon West) This is the newest and fastest growing area. Well planned with easy access to Disney. Probably the most expensive area as a whole, though Windermere is pricier than Winter Garden.
East is Dr. Phillips and Williamsburg (Sea World area). Older well developed areas. Dr. Phillips is expensive, Williamsburg is more modest. Good access to Disney on I-4, but not the best commute. Can feel touristy in spots.
South is Kissimmee, Celebration, Four Corners and southern Davenport. Most reasonable costwise. Lots of short term rentals available. Good access to the southern part of WDW. Kissimmee is the oldest and has the most "sketchy" areas. Celebration is very high cost. Most of the area is older and is in transition. You will definitely know your are in a tourist area.
West is Davenport and Clermont. Very nice, fairly new developments. Southern part has short term rentals, northern part does not. Development started around Rt 192 and Rt 27 and moved north. Good roads to Disney but most trips will be 20 - 35 minutes. Beautiful rolling hills.
It's funny but each piece of the pie has it's own distinct personality. Renting for a year is a great idea. We did and were very happy because we ended up in a different area than we would have chosen if we bought when we moved down.
Sorry to be so long winded
