If the lawyer in a suit against you can prove that money from an LLC was used to pay say your personal car payment etc then they can find a worm hole to your personal assets.

You hit the nail on the head on why its a sub-optimal life choice; its not about finding the best way to make money, its about finding the best way to make money that suits your knowledge skills and abilities. 

Instead, I would recommend looking at properties with a walkout basement, mother-in-law suite, split-level, or even just a separate entrance with street access.

(a) A landlord who in bad faith retains a security deposit in violation of this subchapter is liable for an amount equal to the sum of $100, three times the portion of the deposit wrongfully withheld, and the tenant's reasonable attorney's fees in a suit to recover the deposit.

The stakes are higher (ie higher loan balance, more management intensive) with larger properties (ie 5-50 units) so imo it makes a lot of sense to start smaller and build from there (knowledge, contacts, etc) then when you have a solid base you can cash out refi or 1031 those smaller properties and roll them into larger ones down the road rather that having all your eggs in one large property to begin with (ie sink or swim).    

I currently use Cozy for rent payments, but the right software suite would convince me to go through the hassle of switching all my tenants over.

Has anyone brought suit against the seller for breach in the event they decide not to sell?

LLC's aren't generally the best vehicle for Canadians to hold US real estate, but may be suited for your purpose if it was done correctly.So has it been vacant since purchasing?

@Tony Castronovo this is definitely enough money to file suit in small claims court.

Because as an investor it is your job to determine what asset price best suits your overall goals, which ultimately determines the strategy you will utilize to reach those goals.
