Combine two LLCs without a sale of property?

[Michael C.]

Is it possible to combine 2 LLCs? Lets say I have 100 identical single family homes in one neighborhood owned in two LLCs. 20 are 100% owned by one owner. The other 80 are 50/50 between the original owner and another owner. Can owner 1 contribute his 20 homes to the bigger LLC for 60% ownership in the combined entity without recording a sale/paying tax? The goal is to simplify financing and operations.
