The brokerage firms that sold these “investments” settled class action for a small fraction of what they “earned” in commissions. 

I don't have any ADUs, however I would love to see the creativity in this competition. 

Quote from @Dan Ward: Just looking to hear thoughts on fractional real estate. 

Hi everyone,I’m doing some research on modern property-ownership models and how they could help small investors access opportunities that usually require high capital or complicated paperwork.Specifically, I’m looking at:digital property records (“digital deeds”)fractionalized ownership structuresautomated compliance when multiple investors share an assetwhether these innovations actually reduce costs or just add complexityMy goal is to understand how experienced investors view these tools — especially regarding risk, legal enforceability, and real-world adoption.Questions for the community:Have you come across any platforms using digital deeds or tokenized ownership models?

If you do it yourself probably $15-17/ft.While I appreciate trying to save money I think it is important to mention STR's are competitive to downright saturated in most every market so thrifting is not a sound strategy nowadays. 

I've spent far more than 100 hrs on the properties this year, and my partner has spent only a fraction of that time.

Just points out how ludicrous it is when people with no experience, knowledge and capital believe that by watching upteen hours of puff videos or paying $20k - $50k for telephone access to a failed salesman reading from a script will enable them to uncover properties selling for a fraction of their value and obviously overlooked by the real estate professionals and full time investors active every day.   

Alternatively, you can also purchase a property with a partner with a method known as fractional investment.

If that doesn't work, a group of owners are willing to join in a lawsuit against the HOA and perhaps try to dissolve the HOA or find a way to legally allow STR's.My backup plan is to try and create an LLC, and do a fractional ownership on this property to allow use of it and move on to the next project. 

I'd love to build one day but I find right now with the market we can buy existing homes that are operating from day one from retiring operators at a fraction of what I can buy from.
