Our mortgage payment is $12,849.05 per month.

If you can pick up houses for cash, fix them for cash and hold them mortgage free then you do not need too many to get to 20k/month cash flow.

More specifically setting up an LLC as a Canadian, navigating cross-border taxation, finding lenders, and going through the acquisition process as an international investor.Thanks in advance for anyone who has advice!

If you want to shower me w/advice on my specific scenario:2x Duplexes4% Mortgage Rates / Very small loansMixture of LTR/MTR/STRActive Income (not very passive)Net Income around $24,000 in totality (however my books are a mess and am currently working with someone to CLEAN THEM UP so I can get a clearer picture)Would you a) hold; b) sell and open a franchise or other business venture ?

I would check out Banco Popular or a local hard money lender. 

you can get no seasoning upto 80% as long as the rent covers the mortgage

Lender here.There is a one-time closing Contruction loan out there.

I am going to be paying 10k a month in mortgage , perhaps renting out the other units for 2.5k a pop. 

Assuming you are investing in single family home - I would recommend starting with 25% down payment and having monthly cash flow from a W2 to cover the mortgage for several months in case it sits vacant or needed repairs.

We currently have 3 mortgages but the 2 pay for themselves with rents and have been rented for over 2 years so we are able to use that income to offset those.
