I know where I am going to hang my license as long as my application is accepted and am excited to become a local real estate agent.

For how long?

I do know some people suggest having multi checking accounts for long rental properties.

Typically you can only have one FHA loan under your name at any given time, but there isn't a limit on Conv so long as you qualify.

I think too many people get into this and struggle for too long before realizing that they not been properly trained and potentially could have dramatically shortened the learning curve.   

Use the HELOC on cash-generating opportunities like flips, then use the cash generated to buy long-term buy and hold investments. 

The land banker, the long term landlord, the neighbor that wants to expand their home, or the horse owning owner occupant with no other options?  

MTRs fall into the standard long term rental( 30 day +) category and will follow those regulations set for Long term rentals.

Remaining focused on long-term goals is essential, and sometimes that means being willing to let go of underperforming assets.

Depending on your current rate or if the current loan is short term or long term.
