I'd say all the Equestrian you can enjoy. Beautiful.
I love Lake Nona it is a very wonderful area to live. I would check out the police reports from the newspaper The Orlando Sentinel for Lake Nona. Or MyFlorida.com which has lots of local information. My office is in Lake Nona, it is a growing community.
You can check out homes on Zillow & contact a Realtor for that area.
I have eEdge through Keller Williams. It does everything I need.
I agree with the answer already posted.
My advice is speak directly to a lender.
Lake Nona & Doctor Phillips schools are known for being sought after school areas. try this site: http://www.greatschools.org/florida/orlando/
