[BEETHOVENMIKEY]

I ran into the same issue when we bought our villa, here on the north side. Property surveys are not required, and unless previous property owners marked where the survey flags were placed during an actual survey. We ended up having a survey done and I got four timber spikes, about 12" long and large flat washers for each, and drove them in the ground at each survey flag that the surveyor left. This way, knowing approx where they are, I can find them, if needed.
Basically, in our Villas, the property lines run up the middle, between the houses. Technically, half our concrete patio is on our neighbor's property.
The front and rear property lines will vary, depending on easements and right of ways. In the rear, ours, much like the side lines, run down the middle, inbetween the houses.
2. I called TV for assistance in understanding who's responsible for what.
A. Rear property lines: you are responsible for maintaining up to the property line and around any utility. No obstruction may be planted around utility.
B: Front property lines: ours run approximately 10 ft in from the edge of the road. We are responsible to maintain grass/property up to the edge of the road. No plantings permitted in that right-a-way.
C: the screwiest for last: Side property lines: different neighbors on our street had different understandings of responsibility. TV quote: when you look out your patio door or lanai, you are responsible for maintaining, plantings, and care of all you see. Any bushes, plants or grass up to your neighbors house, are yours, even though it's physically on your neighbor's property. Your neighbor has property rights to come on that side for access and care to their house.
The kicker: I asked for what they told me in writing and was told that it is not in writing and they will not issue anything in writing.
In short: (my interpretation) they want to be able to change things, when necessary and do not want legal responsibility for disputes.
On that note, I took out 6 bushes along our neighbor's house. They were overgrown and had black snakes in them and neighbor's have stated they saw rats in them before.
