Keep track of your rentals every season. Sometimes the cheapest card is not the best. Look for ppl who don't cancel rent and renew the card on a daily basis.

To me the best profit come from gold 3 to 1 in terms of investment. This is mostly based on how much you can afford but I would say closing G2 it's a good balance to avoid bots at the start of the season.
