These people are offering (for about $4000) to arrange a deedback on my timeshare. Does anyone have any experience with them?
Save your $4k. No one (including some obscure and dubious entity which may or may not even actually use licensed attorneys in the first place) can somehow magically "arrange a deedback" any better or any sooner than you can do for yourself ---
if your resort HOA accepts deedbacks at all.
Contact your HOA President (in writing) to inquire about "deedback acceptance". Whatever the answer is, rest assured that the HOA President cares
not one bit whether that question gets asked by an owner representing himself / herself, or whether it's asked within a letter from some unknown entity representing an identified owner. The "deedback" answer and the associated details will be exactly the same in either instance.
Initiating a "Bargain Deals listing" as already suggested above and overtly offering to pay
all of the associated fees to transfer ownership to a new "grantee" costs you nothing, is quick and easy and surely worth the minimal time and effort involved. If you find a willing new "grantee", total transfer costs will also certainly be a lot less than $4k, even if you have to offer to pay the maintenance fee bill for the new willing recipient. Good luck.
