Howdy @Jordan Jensen, great question. Congratulations to you for taking all the steps to get to this point.
Although I'm not in the DFW market, I am in the Milwaukee market which is also in a historically low inventory position. So, I will dispense this advise generally, as it can apply anywhere. The only caveat I have, is that every investor's goals, resources, and strategy are all going to be different. Okay, to the answer you're probably looking for...
Here in MKE, many of my clients (and tons of other live-in investors) are certainly finding House-Hack success. Here's a quick guide to success:
1) Finding Deals:
Establish your Goals - First, think about, write down, or know by heart, your goals and your "Why" - why are you investing, and what do you want to achieve.
Next, create a "buy-box". Be sure to eventually narrow down your specific buy-box (your investment property "avatar" based on your Goals, Returns/Appreciation). For example, my buy-box is 4 bed, 1.5 bath side by side, larger sqft duplexes - based on my goal to achieve "okay" (slightly positive) cashflow now, and reap the benefits of higher chance for appreciation and cashflow growth over time). I forego better "cashflow" opportunities, but look for greater appreciation opportunities - they're generally on a linear "scale", opposite from each other, but blend as you slide along that scale.
By setting your buy-box, you can at least narrow down your search. You can always change your buy-box, but it's great for focusing and helping avoid shiny object syndrome.
Yes, you can find deals on the MLS/Zillow. One option - (looks like you've already taken this route) - Shack up with a local investor-minded realtor, they will be more than happy to set you up on a specific, filtered investment property drip campaign. Now, these on-market properties won't be as lucrative as driving for dollars, or securing another type of off-market find, but it's one option, and you would have the help of a fiduciary (Realtor, looking out for your best interest). Otherwise, you can take on a bit higher risk and acquire an off-market opportunity yourself, but you will not have the guard-rails of a Realtor and Lender to keep you away from expert-eye (or obvious) pitfalls.
2) Tools and Analyzing Deals:
What Tools - The analysis can be done via the BP Calculator (lucky for you, you're a PRO and have included access). Also, there are tons of home-grown (free, shared) calculators other investors have created if you Google for "Investment Property Calculator".
Analyzing The Deals - You, the investor, need to put on your blinders and practice underwriting (running the numbers) before you jump into a competitive offer scenario, or getting too far in front of your skiis with an off-market deal. Pull any ol small-multi-family properties off of Zillow and chug away. The first 5 times will be painful and frustrating - watch one of Brandon's or David G's videos on how to run the numbers - you'll become quick after a few dry runs.
Just make sure you underwrite the deals against your Goals (ROI %, Cashflow $, potential longterm appreciation, etc), and run the numbers as if you're NOT in the property. The purpose of house-hacking, as you're aware, is to benefit financially from another tenant/roommate subsidizing your cost of living. This can be a small amount (again, based on your goals), or significant. Currently in DFW (assuming, because MKE may be similar in this regard), I would find it a surprise if you cover your cost of living completely (i.e. living for $0, or getting paid while in the unit) at this time of relatively higher (read: historically AVG) interest rates compared to 2-10 years ago. Look at it this way - if you reduce your cost of living from $2,500/month to $1,750 then, hey, you're saving money, but you HAVE to make sure the INVESTMENT property will be a true cash-flowing asset after you leave (inevitably, someday, you will). So always underwrite your numbers like you were never in the property.
The silver lining: You certainly can find a deal within the 0-3 month timeline.
Hope this was a little helpful! You have the right wealth-building mindset. Your first deal will not be a home-run, and it will not make you wealthy (except for the knowledge you gain). So congratulations again on building your capital, now take ACTION!
