IRA Services Trust Company is often used by my clients.

Syndicated deals are most often done with financing than not, although I have participated in some where only investor money was used - ie: not leveraged up front. 

I have rentals class C to C+ rentals, holding out for a 650 fico would often mean more vacancy and lower rent, so I elect to be more flexible, and probably take on greater loss risks than you do.

One group I see pretty often are the Rain City guys who I believe buy on behalf of investors.

Also what @Michael Ablan mentioned is something I do often as well as long as I am confident the property will appraise higher than the purchase price, I'll ask for a seller contribution to closing costs so there's less cash to close on the buyer's end.

@Michael Bishop is a syndication pro at this kind of thing.If you're flipping apartment buildings (5+ units) then syndication may be a decent choice.If you're wanting to do residential deals, I've most often seen a JV work best because then it's a deal-by-deal basis, and the securities aren't tied to one house)

For example, one of my tenants never missed a payment in 6 years of tenancy although he was late several times a year. 

These duplexes are often above 2.2 million.5.
