@Abhi Jain, apologies as Im not knowledgeable enough on the Torrance market myself but my parents have had one SFR as an investment property there, in a B/C class area. They've had it for over 20 years so it's probably irrelevant to find out what they paid, but I do know that recently their latest tenant had move out After very short notice, and my parents seemed to have a new tenant lined up within a couple days. They've never had a problem filling the property with tenants either, and a lot of the older homes have a guest house you can rent to a second tenant as well. I will leave it to others to better say whether it's a good area for investment, but my parents seem to have done just fine and this has been their only investment in RE. Their property is a couple blocks from Mitsuwa the Japanese grocery market, not sure of the exact street. Hope this helps a bit!
Also want to add that my parents haven't given much time to investing in RE education so I would still consider them beginners who invested in Torrance successfully. They self manage but that said they are more than happy to put a ton of time into this one little SFR, perhaps you might want to read a bit in self managing properties to see if that would suit you.
Good luck!
