I'm sure that what you see in all the big sites are just a fraction of what's available.thanks to you both 

But the fractional number of people who have retired early does not justify a movement where people may be misguided to make enormous sacrifices to achieve a goal only to be faced with a significant problem 20 years later.

The tenant only payed a fraction of the entire lease. 

Their premiums and deductibles are a fraction of the cost of their peers their age.

So selling one and buying two or three cheaper properties is fine or a fractional interest in a dst as @Brandon Bruckman says. 

I play the CC rewards game a lot, and as we know, if you can't pay off the balance in full every month, the interest will typically outweigh the benefits.You also have other challenges: how to get the cash off the card (most cards allow cash advance but only for a fraction of the CC line). 

If you were looking for a cannabis dealer in your area, some may sell you crappy cannabis for crazy prices, then you find someone who has great potent stuff, knows his product, sells you a variety of different strains, edibles, and oils for fraction of the cost.

The note is secured but the collateral (land) is only worth a fraction of the amount due me.  

I'm considering offering a fractional ownership share of it.

You are going to have a much higher chance of getting one of them to sell you their house at a fraction of it's value than you will in an affluent neighborhood, full of people that are more likely to understand money and have their **** together.
