Hi, new to MMM. I keep a lot of cards and my friend recommended me to this thread. I am definitely interested but looking to draw on the experiences of others. I need to decide if it is worth the time investment or if the market is oversaturated at this point. The 2 cards I would like to use are citibank and barclay (I think that these are two of the easier ones to use). Each card is 2-4 years and $10k-$15k. How much money would I expect to make off this?
It's pretty saturated, so I'd expect to make hundreds (possibly low thousands), rather than thousands (or high single-digit thousands), per card per year. Whether or not that's worth the effort is up to you.
The hourly rate on whatever you sell is pretty insane (over $1000/hr), it's a very low amount of work.
Also, does it make sense to open a PO box (to keep creditors away from my home address)?
Depends. That's just a calculation on how you value the cost of the item versus annoyance of the event times the probability that it happens.
We've (collectively, as a group) now sold thousands of tradelines, and had:
1 report of a collector knocking on someone's door.
2-3 reports of a collector placing a phone call to someone.
3-5? reports of receiving junk mail for a previous AU.
The odds of it happening are pretty low. The annoyance if it happens depends on you. The cost for the PO box varies.
I'd just run all that together and make a decision.
