With our law that allows either the tenant or the landlord to give a 20-day notice to end the tenancy, we can act quickly to move out an undesirable tenant.

Rule breakers don't feel comfortable renting from us and either don't apply or move on.We also have a strict "no smoking" policy, which doesn't allow smoking anywhere on the premises, and that alone weeds out many undesirable people and helps preserve the property.

That would require us to empty out a unit with a perfectly good tenant, move into an apartment that we don’t want to live in long term, wait until our desired unit is available, kick the undesired tenants out after a year, and move for a second time...

There has to be a way to draft language that makes it undesirable for the tenant to want to sublease a space.

Examples include office space, machinery and equipment, vehicles, computers and peripherals, and real estate.Besides renting the assets personally, you may use a multiple entity arrangement such as partnerships, S corporations or limited-liability-companies to rent the assets to a corporation.

I've tried to sell these lots for $1000 over the past year and been told due to their location/slope, they are undesirable/worthless.

Redwood City has parts that are undesirable.

Here in CA, the challenges to development from a regulatory perspective make development undesirable for business people who take risks in exchange for profit. 

I will hate for you to place your private funds into undesirable areas, confusing condos, rusty mobile homes or go with an unscrupulous "partner".   

So, at least in my market, sellers that offer seller financing only do so because the property has major issues keeping it from being financed in the first place, or they are can't get any other offers for whatever reason (undesirable area, etc).There's a lot of talk on BP claiming seller financing is a great way to get into investing.
