These are my most vulnerable tenants.If I do not raise rent on my 2 rent controls I lose it forever as any future increases are built on a percentage of the prior years rent.

Then, if you can also be a member of the LLC which has ownership of the property, then that would also help you from being as vulnerable because it could give you some form of control.

That said, there are different entity types that may be beneficial for a flipping business (LLC, S Corp, C Corp, etc.)For rentals, there is a degree of personal preference - some like to have a separate LLC for each investment, some use Series LLCs, some group a few investments in a single LLC until a certain threshold of equity is met, like @Tanvir Sattar mentioned.Although, I don't typically agree with that method because the investments within that LLC are still vulnerable to others within that same LLC.

It might be prudent for you to figure in a monetary or other compensatory allowance for yourself since you wish to assume this risk if you choose to leave the asset vulnerable.    

@Charito Mattson thanks for being vulnerable and sharing your experience.  

We would rather sell It at a deep discount and build capital than a vulnerable portfolio. 

I get that America has some signs of economic health and strength, but I also see some vulnerabilities.

And with revenue-generating websites, while a hell of a lot more stable, it's still vulnerable to stiff competition and changing trends.

I like cash flow, because it is allowing me to grow (or pay bills), but equity helps me to sleep at night knowing I am not as vulnerable to changes in market rent.

You can really be vulnerable when all the new info and promises start flying around.
