PM me and I can send you the name / number of a good local realtor who can point you in the right direction. Resorts like Windsor Hills and those in the same area are all STR (short term rental) vacation communities. All of the homes are generally furnished also. You also wouldn't want to pay the weekly rental rates for a whole year. Windsor Hills, for instance, has I think 5 people / homes (out of 1000) where someone actually "lives" there, the rest is all people's second homes and vacation goers to Disney.
Now, say weekly rental rates are roughly $1k/week....out on 27/Clermont area I know you can get a monthly rental unfurnished for well under $2000 a month, for a whole house. There are STR rental communities in the area, and longer term rental areas, the Formosa Gardens area / Old Lake Wilson area though is mostly STR as far as I know (which is why I'd call the realtor and ask where to look).
I can tell you where to go stay for a short term Disney visit, just not as much on where to live in the area. There's a few board postes (I think DUCKLITE is one, TEDVNON is another) who live right in the area, and could probably offer good advice as well on where to look for the longer term.
