HELOCs only make sense as short term funding - especially with rates where they are now. 

Hey @Adriana McLaughlin - This is actually the FIRST TIME I have heard of the term "ALL-IN-ONE-FIRST-LIEN", but after doing a little bit of reading on it I am not sure I still completely understand.Basically, you apply for a HELOC credit payoff your existing mortgage with this variable HELOC and then in theory have some leftover as well...so the advantage is paying off your loan early and getting access to a line of credit, but the disadvantage would be a variable rate mortgage for the reminder due on your orginal first mortgage? 

@Andres Ruiz decades long debate about which lease term is better!

I then thought of the idea to offer they a fixed rate if they private lended me cash on a short term (5-10 year) period.

Their longer term goal is to use the money you give them to put you out of business.  

If they are in the lease term then they are responsible until it expires.

I'm thinking of investing in a property in Miami (Edgewater area) for short term rentals.

So you never think in terms of hours worked or which day etc etc its what you do to live ..

@Renzo Roffmann property taxes alone are not a reason to sell.RE investing via rentals is a long-term process.Advise that you wait a bit longer and really work the property before making a hasty decision.Can you also STR the lower unit?

I can still remember the moment we got the term sheet for our first deal and happily signed it, thinking that was the end of the talks.
