If you borrow $100,000 and invest that in a property, you are paying the mortgage on the new property and the HELOC on the money borrowed.

Now this number will change if the person pays off early, etc. 

Rentals have also shot up like crazy so I anticipate much more as the years go.I have been studying BRRRR and leveraging debt but this case is different.Would it be in my best interest to pay back the loan asap or just make the monthly payments and start saving my extra cash for my first BRRRR in the states. 

Do they take care of the place, pay rent on time, etc? 

I don't pay for an exterminator, and don't want to start. 

I am a licensed Real Estate Agent but I am not a broker, I pay my broker a fee for holding my license similar to a commission split but its just a flat fee. 

Tenants pay for background check.

I now have the EMD lender blowing up my phone saying he needs to get paid and if I dont pay him by a certain period or pay more money due to the length its been he is going to "blast" me on his social media and stating he is the "last person I want to mess with", is this allowed? 

I had no idea how to do the analysis but was happy that someone else had done it so purchased, paying all cash.

Either pay a pest control company to handle it for you or take 90 minutes - 2 hours and do it yourself.
