Texas real estate comps

[Amir Khan]

Texas being a non-disclosure state, I understand most "free" online resources are not reliable source of pulling DFW area property comps (unless I am missing something?). As such the only reliable way would be to get real estate agent who has access to MLS pull them. Those of you who use Propelio, do you know whether the comps listed in the their system comes from MLS? What about properties that were never listed on MLS and sold by the seller (FSBO)? How does one go about finding sold comps for FSBO properties? Thanks.
