I need a recomandation for a bank that provide loans for multi family property. 

Bank statements?  

A private installment note between two private parties (no banks). 

Is there any benefit to using the bank that holds the primary mortgage?

Some jurisdictions state that it is illegal for a unit to NOT have control of their own thermostat.

How would the bank know if it were my funds or not when it was purchased?

Probably is I can’t find the 300,000 banks want to have 20% down.

I work with four banks.

Given the average rent in the GTA and increasing interest rates the stress will become even more extreme if let as it is.Housing shortages aren't cured overnight.And a heads up. some of the big 5 banks appear to be increasing their posted rates.

Quitclaiming the property to your LLC owned in your name - and the name of your spouse if you purchased the property as joint owners (read my previous post above) is only part of asset protection you want to pursue.Yes, "Sam the human" pays the mortgage, not Sam the LLC - but understand that Sam the human is the person who's name is on Sam the LLC's bank account as an authorized signatory as Sam the Managing Member.
