The strategies he's talking about are legit but it aint no easy walk in the park. The minute somebody hears no money down or some other catch phrase like that everybody either gets hyper excited or immediately yell scam.
Always slow your roll and do your own research. That's ALWAYS the rule. Half of the people will try to talk you out of it and the other half will hype you up to jump into different schemes all willy nilly.
I was in the game years back on the foreclosure end and boy it was way tougher than the infomercials. You can find property easily enough cuz everybody tryin to get paid and unload their property for top price. The number one problem was finding the buyers. They got the cash.
Vid was interesting because he mentions wholesaling and having a buyer's list. That's crucial. It's kinda like being a real estate bird dog which is a common term but some shy away from that due to legal issues in certain areas but that's another story.
Best to get with some attorneys too before you begin because assigning contracts with people's property can get a little legally tricky as well. A broker open to investors is invaluable as well as friendly title companies like dude said. All that helps you to CYA right off the bat.
Homie this can be done but it will take some work. It might be a year before you close on your first property. Then again it might jump off in a few months. In any case this is hard work with a steep learning curve. Any guru talkin about making ten or twenty g's in a month or so is not keepin it real with you. That's hype.
That buyer's list thing is crucial though. This vid explores that a little bit:
Take your time and do some serious research. Talk to some local investors, realtors, brokers, owners and attorneys. If you are serious about the game put the work in and don't get caught up in sales hype. It's real out here.
