You need to take a step back @Jayme B., because I hear you asking the wrong questions, and with the wrong focus.
First you need to decide if your going to INVEST that capital, or Launch a Business with it. And yes, these are 2 very different directions.
STR is a BUSINESS. Yes, it has a component of Real Estate, but it is NOT Real Estate Investing, it is HOSPITALITY business. The "STR Trail" is strewn with graves marked "I thought it would be easy" and "but the books said". NOT everyone can do it CORRECTLY, well, proficiently, profitably. Problem is many get confused for fact any can do it, with any can do it PROFITABLY, which no, MOST don't. Just look-up AirBnB, look at all the janky places, charging near to nothing, with few to little bookings, and then that "one" jumps out that's booked solid. Now think, that's ONLY those failing now, today, that's not the grave-yard of those who already failed.
STR is a HOSPITALITY Business, and coming into it with anything less than a focus on building a Hospitality business is planning to fail.
And that whole needing a 4-sure homerun hit out the gate, STOP, that does not exist in a startup business of any kind more or less a hospitality business which is one of the single most competitive in existence.
You want assurances, INVEST via a Pro. Yeah, it means lower returns, but that comes with safety. You don't know, so put your $ with someone who DOES. It's just that simple. And than learn from the experience until you grow your knowledge base to be empowered to do something on your own. Book smart is still only book smart and trust me, once in the trenches, with your $ on the line, yeah things are a whole lot different.
This $3k mnthly cash-flow off $100k, not realistic. Not to start, with low risk etc.. Reward and Risk are a married couple, you don't get more of one without more of the other.
