Right now, I am curious about, but not anything close to sophisticated on, office, especially in the suburbs of Denver where I live.

Here are a couple of developers you should take a look at Trion Properties, their principal Max Sharkansky posts here on BP, https://www.biggerpockets.com/blog/top-5-markets-multifamily-rentals-2019and Feldman Equities out of Tampa (3rd generation real estate family famous for having built the terminals at Chicago O'Hare) who are among the only ones opening up downtown skyrise office buildings to accredited investors.

You must keep the tenants security deposit at a bank that physically operates a branch office in the State of NC.  

.- Generally landlord-friendly state, no rent control- Secure government jobs/contracts make the real estate market much more resilient to recessions / major corrections- 15-minute drive to the Capitol of the United States- 4 Seasons- 15-minute drive to Arlington, Virginia (Amazon Headquarters 2 ((2017 announced, 2030 is bringing 25,000 new high-paying    jobs to the area)), Boeing Headquarters (2022), Microsoft Headquarters (2021), CoStar Headquarters (2024), Bloomberg    Headquarters (2017 expanded), Deloitte, and the list goes on)Thesis:Although more companies continue to go back to the office, there will be a shift toward a good amount of workers being able to be in hybrid roles.

Interesting to see how feasible this will be. 

Unless you recast your mortgage (talk to your loan officer about this potential option) your payment will not go down for the life of the loan, even if you owe an incredibly small amount. 

I am a Canadian looking for Loan Officer and Mortgage Brokers who specialize in helping Canadians and DSCR Loans.Looking to see-1) What's the minimum down payment required?

Not all loan officers are created equal so if you call up a branch, you are likely to get assigned someone inexperienced. 

Businesses often times have multiple officers. 

Pretty much my first step should be work as a loan officer and then the rest will come to me?
