@Caleb Barnum Good afternoon and thank you for your service. The BRRR method is a great way to break into investing and if you couple that with house hacking you can get in for very little money down. Your particular situation qualifies you for a VA loan which you can use to purchase a property up to and including 4 units, the caveat being you must reside in one of the units. One potential pitfall however is that the property must pass a VA appraisal process, one requirement of that process is that the property is livable by VA standards which will limit you on the scope of work required on prospective properties.
In order to be successful in this method you must also have a good handle on current value, and after repair value and be able to nail down repair costs, a miscalculation on any of those three variables and what seems like a good deal could burn you fast.
The best advice I can give you starting off is first to figure out what your goal is, you want to invest in real estate but to what end? Real estate is a great opportunity to build or preserve wealth, it can be a means to lower your housing costs, provide passive income, preserve and build on accumulated wealth or to help accumulate wealth. You can be active or passive, and there are a myriad of different ways to do both hence the overwhelming part. So again figure out what your goal is for your real estate journey, once you know where you want to be its easier to figure out how to get there.
Market research is key, the better you know the market you are operating in and who the players are the easier it will be to find what you are looking for and also know what you are looking at. Market research where tell you where you want to be and where you don't, and give you a good idea of what to expect out of a certain area or submarket, this will allow you to move quickly and surely when an opportunity presents itself and help you with valuations.
Analyze everything, start looking at the properties you pass everyday, pick one and research it from address to strike price do this until you are able to get it done quickly and efficiently don't wait until there is a deal in front of you to try and figure out how to analyze it, its to late to figure out how that game is played and what numbers work and don't when the contract is in front of you do that home work before hand when the clock isn't ticking.
Finally this, Networking is key both online and in person, look into local REI groups and get active on the forums, get used to talking to people about RE and your goals. Talk to folks in the area you want to invest who are out their doing it and see what's working and what is not. Reach out and touch everyone you can, Agents, owners, sellers, buyers and other investors do not solely rely on MLS and Zillow to find what you are looking for. You can absolutely find a deal on the MLS and Zillow but just remember so can everyone else and once it hits the market the price goes up! Ask questions, ask a lot of questions and read books that relate to your goal, I have found that most people in this game are super helpful and want to give back, all you have to do is ask. Always try to add value, give more than you take, follow up and follow through that's the key to networking and building relationships in this business.
