Not exactly sure what line of work you're in now but as a caveat if you have no other source of income, do not leave your main stream. 

With triple net or any single tenant with gross etc. when a lender does a loan where the only income stream is one tenant they do a current value and then a dark value at the same time by the commercial appraiser.One value is with building occupied by a tenant and paying rent.

I figured out that since I controlled the account, I got the streaming service with my owners login. 

This way you will even have additional revenue stream coming while you stabilize your financial situation.Reach out to wholesalers and get on their mailing list to look for deals.

If you get a 30 year rate loan, you will be paying a smaller monthly payment but the aggregate stream of payments you pay will be higher. 

We have noticed a considerable drop in streaming quality which could be the reason.The weird thing is that electricity and gas are included in our monthly rent, so I don't really understand why he would ask us to provide the internet, he could have done so himself and increased the rent to reflect that?

These programs are much more lenient and allow Alternative income streams to qualify such as: Liquid Asset calculations for incomeBusiness Bank DepositsPersonal Bank Deposits Expected Income New Employment income1099 IncomeCommissions & BonusesAccount ReceivablesNote Receivables Contracts for future incomeNew Rental IncomeExpected Rental Income from property planning to rentConsiderably different calculations on Tax returns 

I am also an engineer (mechanical) looking to generate a passive income stream to supplement my day job.

Hey John,I think you bring up some great questions and points.On 1 hand, you want to start investing and creating another stream of income, on the other being an agent won't get you the loan you need. 

Once paid off they will be nice income streams.
