or what if they want to rock out to music while you have a business meeting?

Lotsof different industries combined with a really good music and art scene does make us Austin-ish.  

Walking noise is rarely an issue with tenants from my experience - but loud music, television, screaming, arguments, dropping large objects, barking are the ones that tend to annoy tenants and landlords alike. 

My 2023 goal is to partner with someone(s)on a ~500-acre village in Tennessee (willing to consider other states if the land is right) by the water consisting of: A-frames, tiny homes, glamping tents, and treehouses complete with amenities I have come across on my travels: zorbing, zip ling, outdoor movie theater complete with stationary classic cars and space for outsiders to bring their vehicles in to park, above ground shipping container pools with see through plexiglass, lake blob, monthly mini burning mans, pool/sand volleyball, outdoor music venue, drone racecourse, 3d print stations, planetarium, and other ideas to get people to "stop the scroll" and provide the most unique experience imaginable.

Or, I'm recommending he invests in whatever instrument he can get 12%.  

You give them something complex and different from the way they have always done it and most say (no thanks).I see the traditional way of transacting staying around for a very,very long time.Most people like to keep their lives simple and do not find enjoyment in complex instruments.

HELOCs are short-term instruments so I wouldn't stay in a HELOC. 

Example:  Your daughters- music, softball, tae kwon do, young in daycare, etc etc. 

I really don't know any lenders that would do that... especially in a mortgage state were foreclosure take a year or so.Are you sure of how they structure these deals are they truly loans in the first place IE they actually record a security instrument that in the case of default needs to go through the entire foreclosure process. but to answer you question the only alternatives I know of are1. friends and family2. some one you meet and is very Green and naïve in the ways of investing and loans you money at a low rate etc.Alternatives:Just find an equity partner.. you do the work they put up the cash. split profits give them the lions share to start and work your way up. 

Hub City Title in Lubbock was instrumental to the success of this deal!
