Lake Nona has had about a 10 year headstart on growth (and appreciation) where as Apopka is just finishing up the infrastructure in the next two years and becoming built out by new builder neighborhoods expanding north and west from the city center.

I'm more excited about watching Strawberry Fields develop than I am the Wheeler District because it will be part of the overall redevelopment and expansion of the downtown area from the new convention center complex, park, and Strawberry Fields.

I can't speak to appreciation much with great certaintiy, but as long as they continue to build shopping centers around Clarksburg (example is the new outlets), there could be potential for even greater appreciation over time. 

If you are looking at it as a short term rental you want to make sure there are no local restrictions in the various municipalities and pick something that is relatively close to tourist sites, convention centers, concert venues etc. 

PLACE: The front lobby of the Polk County Justice Center, 1005 W.

Here in RI, we have the RI Small Business Development Center - which is an awesome resource for helping grow and focus a business. https://www.risbdc.org/Documentmaster.aspx?

What about a strip center?

I am interested at similar development of a retail center and occupy a portion of it while leasing out the rest.

@Arturo Borges, it might be helpful to combine this with your other questions about shopping centers. 

Does the 50% rule apply when acquiring shopping centers?
