Buying Resale DVC points?


Trying to dig our way out of debt and because that meant no Disney vacations I haven’t been on here in FOREVER! :frown: I tried to find an answerin past threads but don’t remember my way around all that well.
Yet now my Mom needs more points for family vacations that she has planned for the next 3 yrs. She is wondering about resale points. She is on a reslae site and just wondering if doing this is safe and secure and any extra info that anyone can share. Or a direction to point us into.
I think she is wanting to stay in AKV where her other points are but isn’t stuck on it.
