I'm not a guru but feel free to message me if you like.

This was not like taking out a regular mortgage, There were all sorts of hoops to jump through and tons of extra paperwork to fill out but my Realtor and Lender made the process easy!

Get pre-qualified with a mortgage lender - I have a recommendation if you'd like. 

Since we will likely be on the go but can have our permanent address be set at the property we purchase.

It seems like other than capex that the landlord is responsible for (typically roof and HVAC) there aren't many reasons why I wouldn't achieve the broker's forcasted NOI. 

It seems like everyone is charging for coaching and courses now.

Get good tenants that won’t likely cause issue (background check, credit check, references, pay stubs).
