My strategy and what do I need to know about 1031 exchanges?

[Nate R.]

I'm planning to focus on acquiring SFH's and possibly duplexes. Over time, I plan to acquire a portfolio of these. When I accumulate enough equity, I would eventually like to be able to liquidate these and replace them with multi-family residential.

Is this possible? Can I exchange multiple houses for a complex as part of a single 1031 exchange? 

In another thread, someone commented that the sale of a SFH would barely cover the legal bill for a 1031. I would assume that this math would be different if 10 houses were involved.

Perhaps someone can clarify?
