More potential buyers because the buyers no longer have to worry about repossession by the original buyer.
Higher resale price because the price is not depressed by the possibility of having to give the property back & lose what was paid.
If I understand correctly most thefts are by drug users. The good faith principle will lead to higher price (since to low price will not let you use the good faith defence) which mean less theft to finance the drug use.
I do believe the situation is so complicated so you cannot even guess what would happen without doing empirical studies.
