I would think the two types of units are pretty easy to distinguish...In anycase, since the unit is not subject to rent control, if you and your 3rd party consultant did your homework with what units of comparable size and location were renting for, eventually this tenant will lose.

The assets of each series must be clearly distinguished and not comingled with the others, but each series operates separately and distinctly from the parent LLC and other series. 

Obviously, there are many factors involved in this and it is difficult to distinguish exactly which repairs increased value by however much.

This is why I am so against leveraging oneself to the hilt, taking out all equity to buy another property, etc. 

A good landlord is also not a 'yes' man/woman, a good landlord is able to distinguish between needed repairs and selective repairs and is still able to say 'no' while still keeping the tenant happy by conveying the why.

I've managed one self storage facility where I was able to increase the occupancy by over 20% in just a few months, just by being a good manager.

Also, what are the boundaries of "holding oneself out to the public as being in the mortgage lending business" ??

Being able to distinguish between what I know, and what I think I know. 

@Cristopher Andrade take a look at the Hospitality Guide from The Distinguished Guest.

Those who don't distinguish between "good" debt and "bad" debt just want to get out from under it.
