Check the Ontario Act to be certain you do not have a similar regulation.Also check the act to see what are your restrictions on raising rent ... her we have the concept of a long term tenant (tenancy >5yrs) which places some additional restrictions on termination of lease and how rents can be raised.I doubt you can ask for a vacant park ... unless you were planning to redevelop the land ... even then, you may have to compensate tenants ... again, read the Ontario residential tenancies legislation.

But when tenants have added rights supported by the government rent control legislation and if the tenants KNOW their rights you might lose way more money than $400 for a stove on eviction proceedings, then you add the make ready and time of vacancy...soon that stove issue will cost you thousands. 

You first need to find a good value add play (given recent legislation, adding inlaw units is now a new twist on that).  

Looks like some Atlanta condo building is fighting its residents over Airbnb ... and this building happens to be a condominium where numerous state legislators own.

This year I have, I believe, found a loop hole in the legislation that allows me to raise the rent between tenants to market.  

I know what you mean, of course, but Rent to Own is addressed specifically as a predatory tactic in recent legislation.  

I haven't done enough research to know if this legislation is going to force cities like Lincoln, who have discouraged these options, to allow these kinds of additions. 

@Wayne Brooks But doesn't Obama's federal legislation "Protecting Tenants at Foreclosure Act of 2009" (PTFA) protect the "tenant"?

As @Jason Hartley suspected, Seattle's City Council has in fact created yet another piece of counter-productive, pandering legislation that includes a provision legally mandating "first-come-first-served" applicant selection.

@ Chris Malo - Can you provide more info on the recent legislation?
