Good morning! The short answer to your question is...there is no short answer! There are a million ways to get deals, you just need to pick a method and devote everything you've got to it. You could drive for dollars, send out yellow letters, look on the MLS, look on craigslist, auctions, For Sale By Owner, even just telling everyone you know that you're looking for a deal. The trick is to pick one (or more) method(s) and stick with it.
The questions you should be asking (and the answers to the one's you've already asked) will largely depend on you and what it is you are looking for. A great way to get started figuring out WHAT those questions are is by reading through this free guide "The Bigger Pockets Ultimate Beginner's Guide": https://www.biggerpockets.com/real-estate-investin.... Here you will find lots of tips, links to articles, and podcasts to listen to. By the time you finish reading through that you should have some better answers to your questions, along with new questions to push you even further to the next level. :-)
I'm personally in the market for buy and hold. Or, more accurately I'm in the market for flip and hold. I want to invest in small multi-families and work up to larger ones while taking advantage of value-add appreciation. I recently got my real estate license so that I can take advantage of the MLS to look for my deals. I'm in a very competitive market but there's plenty available for someone who's willing to hustle a little. And that's just one of many different ways to do it.
I completely recommend the podcasts. They are fun to listen to, packed full of information and tips, and the guests do so many different things in so many different ways. It's really easy to get creative just by listening to a week of podcasts!
I hope some of that helped and I wish you luck on the start of your journey. I hope you have a wonderful and peaceful week.
