I am long but I also do fix and flips actively and consistently.

What's common practice?

Is it a good business practice to work with someone you never met? 

Just know there’s a lot of competition, so you’ll need to stay consistent.

As stated in this thread, I believe BL does not let you keep your data if you leave the platform which is not good business practice, IMO.

Also, I'd lease out the other bedrooms for additional income as well as practice screening, leasing, and interpersonal comms.  

These loan officers will be important resources if you are consistently executing on the business plans behind each loan they give you.

I'm probably overthinking this, but is it common practice to provide any kind of cable TV or Netflix etc. in a STR?

If the investor is looking for both appreciation and cash flow; they need to be looking at cities/markets with growth (population and jobs), along with a consistent decrease in crime (all over the past 2 decades). 

It’s given me the opportunity to save and prepare for my next upcoming purchase.I’ve gotten the units from $750x2 and $800x2 to a consistent $900. current mortgage is $2500 monthly, refinancing to a conventional and removing mortgage insurance should bring me to $2100.
