Your cleaner is your lifeline, and even an additional $50/mo to them is a good gesture I've seen workout nicely before.

This accelerates depreciation leading to additional tax savings and cash flow.Historically, a cost segregation study has been a very manual process completed by tax experts and specialized engineers.

I think it is great to explore all your options. 

I have 5 properties of my own listed there, and I currently manage an additional 25 listings for others on Airbnb (plus VRBO, Booking.com and Furnished Finder) as a licensed real estate agent.

Let me know if I can help you explore the Myrtle Beach market, tons of opportunity here. 

Additionally, our agreement allows us an additional 60 days in case title is not clear on the day of closing.

If so, there may be additional fees for services like dynamic pricing or property management systems, especially if you plan on listing on platforms other than Airbnb.Even if you’re going to clean and manage yourself I would get in the habit of paying yourself a cleaning fee so that if you decide to outsource that you can still cash flow.I know the market can be tough at times to find the “right” deal a “good” deal but with patience you can stay in budget and achieve a higher ROI, COC and ROE.

There shouldn't be a bunch of additional cost after that

I highly recommend exploring this investment strategy if your focus is cash flow.  

It sounds like you plan to use it yourself in addition to renting it out so you will get some use from it of value.
