@Joshua Hughes - Maybe what I wrote doesn't make much sense. So I'll try again. I do not know your current financial situation (nor is it any of my business, nor am I a CFP/CPA). I am simply guessing from the first post that you have successfully closed on your first SFH investment and you have it rented and there is currently positive cash flow. If I'm wrong on any of that, then kindly clear up my thickheadedness.
So the part that gave me concern (because I've made mistakes in the past and I am fiscally conservative) is where I interpreted that you don't have any cash cushion. THAT's what has me nervous for you and why I suggest building/rebuilding something that you could fall back on if a pricey surprise on the current property (or your own property) comes your way. Could be a massive roof leak, hot water heater, hvac, or the tenant leaves the upstairs bathtub runneth over for a few days before noticing. For one (or more) of those, I'm inclined to start building a CD ladder as a dedicated emergency fund. Even if that means throwing much or most of the + cash flow into it until you have your buffer. Is that buffer $2k, $5k, $10k? Only you know your comfort.
No, CDs don't pay much (0.8% presently for me on 60mo note), but they pay better than any other easy-access account. They can be cashed out early with generally painless fees (6 months of interest only in my example). Only their interest earned counts as income, so unlike Robinhood/equities, there is no added tax tracking pain such as short-term or long-term capital gains -- or potential for capital loss because the moment the bathtub disaster strikes might be the week after the stock market 'corrected' 50%. FDIC insured accounts protects you in boring and wonderful ways.
BTW, my personal opinion is just that: not a fit for anyone else. I like investing in the stock market (very diversified ETFs for equities, and for bonds, and for REITS). I like US Treasury I-bonds and TIPS for conservative inflation hedges. I like BRRRR (five R's or 4?). I haven't BRRRR'd yet, but I will. All of these tools are great and make for terrific balance. All in on one or the other toolset seems -- limiting? Money is not evil -- how it is used and abused is. Unsecured debt is evil. :) I think everyone should do all of the above with smart financial moves and avoid usury debt products like student loans and credit cards. Everyone has their own model. If we were sharing a beer, I'd ask pester you about your risk tolerance, stress levels, how much can you do or leverage out on before it adversely affects your family life or sleep... and then buy another round. That's an excessive amount of prattle out of me. Have a good Monday.
