They complement LLC as a tool in asset protection strategy - do not confuse them as a replacement.The number of properties per LLC should be based on a number of different factors: equity, number of units, cash flow, location of real estate, and tenants. 

Picture this: Two charming 6-family units beckoning with promise, ready to be transformed into lucrative investments.

One of my units has a rather large door that came off it's hinges. 

When I was 21 I partnered with someone and we bought 2 apartment buildings with 14 units.

The other is a mobile-home, worth almost nothing, that brings in twice as much money each month due to being paid off.  

I’ve also managed units where on our renewal rate we did reduce the rent from the prior year, but for other reasons, such as the prior year of the tenant having a washer and dryer, and a major plumbing issue with the building, preventing us from offering it the following year so we did a reduction.
