Swarm Fund is lying. They say that you need large amounts of money to buy real estate and your money is tied down for an indefinite amount of time. This is false. You can buy one share of a REIT, and there are thousands of REITs to choose from, and you can sell it one minute later.  If they start off their pitch with a lie, what else are they lying about?

There is another flaw with Swarm, which is similar to the flaw with CombiCoin. You will have to trust that the coin is backed up LEGALLY by the land title of the real estate. Who is the owner of the real estate? John Doe? Who is to say John Doe will uphold any agreement that the real estate, that has his name in the municipal records as the owner, will be ascribed to the coin holders? Is there a legal contract that you can take to a court to uphold the agreement?

Atlant and HomeToken have the same problems as Swarm. In addition to that, they both have the same problem as coin banks, exchanges and investment funds. The money is centralized into a honey pot, which makes it attractive to hackers and employees to steal.

Take many of the recommendations on Bitcointalk with a grain of salt. Many of them are pump and dumpers.
