I am ready to get these people out, but it is very difficult in Ontario, Canada. 

Getting lots of LLCs is not always the sign of success, sometimes it is a sign of complication and it gets difficult to keep up with all the paperwork, so very well one could have slipped thru the cracks.#4  Now looking at all the success you have posted about the owner, they very well could fight if they loose it. 

Has anyone else started making the jump form renovating houses to building them new?

Long story short is that my tenant apparently had some friends that stole from a local corner store and were hiding out in my building.

I own a building with another LLC as Tenants in Common.

A common way to build a portfolio quickly is to use creative, out of the ordinary, purchasing techniques.

Lacking the capital and building experience to develop it ourselves, we want to offer the backyard as a "Developer Special" on the MLS.We’d rather not risk demolishing our home at the front of the lot.

<< Most difficult to obtain IMO on smaller amounts.

I have found all my current flips on the MLS and want to start building a system for deal flow in order to grow.

To get top dollar for a renovated property you're going to have to clear the title as it would be very difficult, if not impossible, to find a title company that will write a policy for title insurance on a property coming from a tax sale.
