Fence in the middle of property

[Arvind V.]

Am planning to buy a lot in Austin TX as an investment to build and sell/rent.

The lot is street facing and has adjoining built up homes on the left right and back. There are fences on the left and right hand side but not at the back.

However the lot also has a fence halfway through it. It’s almost as if the rear half was being used by the occupants of the home at the back as an “extension” to their yard.

The survey shows the boundaries as expected and also shows the fence on the lot.

Should I be worried about buying something like this?
