The very basics would be getting your furniture and shopping list together, keyless entry like Schlage (with backup lockbox with physical key very close as well), looking into insurance, local taxes for STRs, and moreAlot of ways to save time and make it easier to self manage with a property management software like Hospitable and data research like AirDNA.

With all this said, to answer your question of how you'd value this for a sale, I'd get a STR specific broker that's able to market your property as a turnkey STR with data on the rents, figures, etc.

Then research local regulations and tourism and data. 

Firstly, well done for persevering and trying every avenue you thought would get you the data you needed.Most would have caved earlier and handed out there hard earned cash for old, saturated leads/records from the same prominent platforms which dump them pretty much when they receive them from either 1).the same large brokers AFTER the county has listed them on the county website or, 2). from the counties themselves directly AFTER the county has listed them on there own website, or, 3). from data scrapers on Upwork/Fiverr who scrape the data from those same platforms AFTER the counties/brokers sell those platforms the data being scraped by the freelancers.Anyway, rant aside you seem to of made the same mistake i made when I first started branching out away from providing leads to my original couple of clients i got from Upwork who wanted me to scrape data from court records in FL for pre FC leads.Simply, I didn't know where to look for the information I needed in states outside of FL.FL only allows the judicial route to foreclosure so I only needed to know/find/scrape the data from Lis Pendens documents for counties they requested.

Also the 1% rule is about as good as the rule thumb and not based on current conditions or current data. 

For example, if the area is rural you might wish to have the house inspected, the well tested, and the septic system inspected by separate services.

My goal for the team would be to have one project under-way by EOY.The exit-strategy of each deal will be dependent on location, market data, and ROI comparisons to determine the best route forward for the team and our goals at the time.

You need to always be changing with the market, testing and poking to see what marketing works better and what does not work at all. 

You can always get MLS data many places.You be the investor, let the realtors do their jobs.

UPDATE:I have been putting my data into this rental hero software for a while now and I absolutely love it.
