I am not so much looking for servicing the monthly payments, but more of creating the necessary legal documents and filing with the appropriate govt entities so that I can place a lien on the title of the RE that we are purchasing. 

And are they legally allow to do so without any signed document from the seller or at least hire them to do title work?

Even when posted abroad, my legal primary residence is always in the United States, similar to military members when they deploy.

From your experience, do you know which legal structure is the best for Canadians investing in the US? 

WArning:  You are asking legal questions in a forum online. 

Obviously this company is up to a lot of shenanigans as I can see in these threads - and - legal or not, I wouldn't deal with them at all.

.- lower turnover- easier on the units when they do move- quiet and less disturbance than traditional, younger- for fixed income, consider partnering with the local housing authority for SEct 8 vouchers, then raise rents accordingly - guaranteed money & the Sr. only pays a portion (if they qualify)Traditional renters- Higher turnover- Higher turn costs- More volatile - higher bad debt- More drug related activities- Adding in children that are hard on units- Higher eviction rates and legal costsConsider all angles before making a decision with the changes. 

You contacted the listing agent, who legally works for the seller and must look out for only the seller - not you.

You may find he never signed the leases and they are not legally binding.
