The plan is to maximize the space we have and rent as midterm rentals to medical and business professionals.

Think isolated towns that are still a hub for rural communities, have a decent medical base, a college or two or three or military nearby. 

Co-housing communities are currently more "mainstream accepted" especially financing-wise.

When we do Joint Ventures with medical professionals, we explain the process in detail.

For example, if the property is currently vacant and you intend to lease to a medical practice, you should make sure the zoning regulations permit the use of the property as a medical practice.

However, no mainstream index fund like the VOO or some dividend index, got forclosed on.

It makes sense as a local because of the density of medical centers.

If one of your tenants gets bit by a dog, falls off a ladder, etc. and they have a bunch of medical bills they can't afford, they almost have no choice but to sue whoever they can to get the money. 

It offers triple tax benefits: contributions are tax-deductible, earnings grow tax-free, and withdrawals for qualified medical expenses are tax-free.5.

I would also invest some in tech start ups, medical companies and other start ups.
