Hi Christopher,
Those are great questions. I personally own and operate both LTR and STR successfully in my area, and hopefully, I can provide some insights for you. These are my honest opinions about the two:
My definition of STR success is based on both reviews on platforms, private feedback from guests, and my financial bottom line. I'm confidently speaking based on my conversations with STR hosts around me, whether they are STR PMs in my area, my wife who worked as a PM for another STR PM company in the past and saw what's behind the curtain, investors who own STRs in my area, and STR arbitrage tenants who are renting my LTRs. I'm operating at the 90+ percentile among all Airbnb hosts, both in terms of customer satisfaction and profit.
My insights on STR vs LTR:
For a quick estimate, you can take 50% of your gross rent income (nightly rate x days x occupancy rate + additional service fee you'd like to charge) to get your net profit. You can compare that to your estimated LTR net profit. Usually, if you only use a third-party cleaner and self-manage the rest, you should do slightly better or break even compared to LTR if you are in an okay STR but a strong LTR area. You will do worse than LTR if you let other people manage your STR.
If you are in a strong STR/weak LTR area (seasonal touristy area), then STR will win no matter how you manage it. This is where you can see STR making 3x LTR income. If you are in a strong STR/Strong LTR area (an area that's both popular touristy and experiencing population growth), STR should still do better than LTR. This is where you see STR making 2x LTR income.
Now let's talk about the operations:
LTR, almost anyone can do it. What you are providing is room space and room configurations. You can have white wall paint, outdated but functional kitchen/appliances. As long as you make things safe and functional, price it right, and screen your tenant right, you put the tenants in and don't hear from them again other than collecting rent every month and renewing the lease or finding another tenant when the lease comes due.
STR, you are in it for the hospitality business (assuming you want to run a successful one). I know hosts who treat their STR like they would with their LTR and they get bad results and eventually go back to LTR. You run it like a hotel business. From exterior curb appeal to interior finishes and decors, everything needs the vacation touch. You have to furnish the place (budget should be $2k per bedroom, counting the kitchen/living room as well). You have to stock the property with towels, sheets, coffee, toilet paper, cleaning supplies, and maintain the property stocked at all times. Pest control and lawn services that are optional landlord's responsibilities in LTR, now they are the host's responsibilities. You can leverage VA, technology, and systems to automate and help with lots of your work, but in the beginning, you are going to handle communication with the guests by yourself. You want your guests to feel welcoming so there will always be a human touch to things around the property that will separate your property from others that are managed by PMs who care less. You are the only person who can decide whether that extra money is worth the extra headache. Keep in mind there is value in learning the business too. When I started my first STR, I went into it with a mindset that as long as I'm breaking even compared to LTR, I'm happy. What I gained from the experience was the knowledge and skills to manage STRs. And now I'm here talking about it :). Now when I make a decision whether to STR or LTR, I have personal experience and data and don't need to rely on listening to other people's stories.
Two bonuses for STRs and LTRs don't have: STRs give hosts more control over the properties, and owners have more flexibility with using the properties for personal use, which LTRs don't.
STRs have their wear and tears, but in general, the condition of the property is usually well maintained above standard. This means that as long as you fulfill your hosting obligations, you can sell the property in its tip-top shape at any time. This rarely occurs in LTR. Usually, when an owner wants to sell an LTR on the market for top dollars, a light rehab is required if not a full rehab. Often when doing the rehab to exit a rental property, you notice you didn't make any money over the last year or two. Of course, as we all know, the cashflow allows you to keep the asset, and hopefully your main gain is in its appreciation.
Here are the insights from someone who personally owns and manages both LTR and STR, and I hope they are helpful for you to make a decision.
