Definitely some interesting discussion. Some really good points. I'm not totally embracing to the concept, but found it an interesting limited explored venture, I just thought it seemed like a personal extension of what businesses do right now. Businesses sell a portion of their net worth to investors every day. Investors are betting that the business will be successful going forward. They get a proportional share of future prosperity. If a business decides to let themselves go (hoarder or crazy cat lady or any other bad business decision) they lose business and investors suffer. Just like a business a home owner typically does not want to do something that brings down the value. Both are pursuing increasing values.
For me the reason for pondering this is I'm about to start a new chapter of my life. Retirement. My plan includes a fixed pension, revenue from a rental that is located on the same property, and of course my savings. Downsizing is an option that I've been considering but it would grenade the rental revenue (at least in the short term). Plus expenses of selling are substantial on a house close to $1M. Plus I have spent the last 14 years making this place nice. Originally a fixer I have remodeled nearly every room + the rental apartment (I'm a licensed contractor). It soon will be more space than we need as my son will be off to college in a couple years. But it is less than a mile from the ocean (always temp comfortable and scenic), which is the primary reason for the steady property value increases. We will downsize but I would like to do it only once to limit costs.
As far as some of the issues brought up about partnerships going bad. I always thought that is what a contract is for. Well written contract would outline buyouts, term length, and fair value assessments at the end of the agreed term. Things like fires, floods, and quakes are what insurance is for and would be part of the contract. I've read about agreements that allow the occupier to make improvements to the property (with investor approval) that bolster value. The occupier continues to pay for maintenance, insurance and taxes. Investor does not.
I even pondered adding to the agreement that the property would be sold at the end of the term. Then also agree to let the investor use the property address for his principle residence for the last 2 years. In essence the occupier and investor switch. Both the original owner and the investor would get up to $250K gain without tax implications using (each living in the home for 2 of the last 5 years). That would be another nice investor perk. Try doing that with a REIT.
Do any of these make it more interesting? Again more food for discussion.
