Overall, my primary goal is to create the opportunity to get into another home at minimal cost while keeping my parents in the current home, so I'm leaning toward transferring/selling the current property to them.

You can use Airdna & other STR estimator tools to get data on potential income/vacancy based on your location and property size. 

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

I’m sure someone will tell you that you can transfer title of the house after closing, but what purpose would that serve?

You may need to seek legal counsel on this.2) Get all the info about your rental property as possible: leases, rent ledgers, tenant contact info, etc.3) Start looking for a new PMC4) Execute your termination notice5) Once transfer is complete, circle back to decide if worth suing them.

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.

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.

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

Could you gift the down payment to your mother in law so she can buy it and then transfer title to you when your house is done?

I would still work with a title company on this and let your lender know (if you have one) of the name change and what you are doing so they do not think you are selling the property.Another option would be to create a living trust for estate purposes and transfer it into the estate.
