My son and fiance had trouble finding a place.

Would anyone be willing to share who they use?

It would be a little different.Like a city place, great view of the city with a nice balcony.

Say $3,300 set in place. 

No other investor will share much, they don't want competition. 

I've enjoyed his content and practical advice - can anyone share their experience with his course? 

Maybe you can convince everyone involved to convert to a community owned system, with a shared maintenance agreement, reserve funds,Just need to find the smoothest path forward to needed upgrades like an above ground cistern, pumps, backup generator, better filters, or whatever to make the system function 100% of the time$1500 is minimal, spend it if that's the way forward.

A couple others, it takes 3-4 hours to do a thorough cleaning, so if guests checkout at 11am the window to turn around the place by 3pm is tight and if there's any unexpected cleaning, you could run into problems. 

At that time, the builder will pay the accumulated interest along with the principal.We have discussed a few different options to structure this arrangement, assuming an interest rate for interest-only loans with monthly payments is 10%:Option 1: delayed interest with a rate of 12% (interest rate is 2% higher)Option 2: charge a lower interest of 8% then profit share (need to determine appropriate % split)Any other thoughts on how to structure this arrangement?

It's at least a place to start.
