Hello @Zach Wright!
Congratulations on graduating! My partner and I bought our first house hack/BRRR in May and are in the process of getting tenants in here now (we are renting 3 rooms). Ill try to share a bit of what I've learned through this process.
-You need cash. You need money for not only for the downpayment but also for closing costs (we had the seller cover most but we still had a tiny bit left), rehab (if you don't do a 203k loan) materials and labor, plus your living expenses (we barely cooked at the beginning since we spent every waking moment with workers and working in the house ourselves so we bought food everyday, we also didn't have a kitchen since we completely gutted the one that was here, and your responsibilities won't stop so you still have to pay credit cards, insurance, internet, etc)
-We became BP pro members to use the calculators to analyze deals and we used the heck out of them. We looked at houses in our targeted neighborhoods and ran numbers in different scenarios. What if your rehab goes over budget? Over time making your 'holding costs' higher? What if your rents are lower? What if your appraisal after the rehab is lower? And we finally decided on the house that we could work in all scenarios. In a house hack your profits will be lower when you live in the house, you might even be negative (like paying rent) when living in the house but should be in the positive when moving out. If you are in the negative, as long as you are less than if you were renting (lets say you rented an apartment for $2000 and now with the house hack you pay $500) then it's pretty positive in our book.
-Go to local REAs, read, listen to podcasts, and ask questions. I have gone to 2 local REAs and have loved it! Ive met some amazing people doing similar things to me. Those monthly meetings have become a great resource of information for me. Ive also read the book on Rental Property Investing by Brandon Turner, the book on Managing Rental Properties by Brandon Turner, the book on Estimating Rehab Costs by J Scott, and the book on Flipping Houses by J Scott, among others like Never Split the Difference by Chris Voss, etc. Reading from others who have done this already and from people who have a different insight on life is definitely something to look forward to every day to grow.
I wish you the best in your journey.
