CA does allow fractionalized Deeds of Trust.. and the general rule is 10 or fewer tenants in common on the debt instrument is fine more than that then securities issues arise. 

ETC would not allow purchasing of fractional notes (Lending Club peer to peer) yet other SDIRA's do (and there is nothing in ETC's rules that would suggest that doing so in not a permissible investment).

Some companies might make it long lasting, but that will be a much smaller fraction.

Banks exist to deliver fractional loans; there's no benefit to denying safe harbor people loans.

In California a few lenders will loan against fractional ownership shares (individual owners of tenancy-in-common properties).

(That statement is actually the most accurate in our situation because we own only a fraction of the total equity.) 

I wouldn’t suggest doing it with all your assets but if it’s a fraction?

Think OPTICS (people don’t look at your reasons for paying a fraction of market value and ignore your fire damage repair costs.Ok, let’s continue.

Even if the information is easily available for a fraction of the price (or free), if it lets you make money, its worth it.

I don't know what you mean by a "lot", we speak in terms of acres or fractions of an acre.
