I also am in the industry already so I have a few regular networking groups and events that I attend.

Our mortgage brokerage works with real estate investors all across the country who face these same decisions regularly.

Preferably contact us by e-mail as we are not allow to self promote. 

The person I want to invest with is able to accumulate cash, in their personal life, on a regular basis, and is not, over the course of many years, blocked by one barrier or another from this accumulation.

Trying to read between the lines it sounds like you have a regular owner occupied homeowners policy in place on a rental property. 

For the second time, I've had a guest cancel a reservation, initiating a refunding through my payment provider that brings with it significant transfer fees because Booking.com heavily promotes their "book for free, pay on arrival" policy, which is not aligned to my management platform policy.

I think this site may be geared a bit more toward the avid investor, rather that the weekend warrior type of investors with regular, RE carriersOn the other hand, for myself, watching the RE market is enjoyable for me.I have always attended open houses just to be nosey or nerdy, whichever you prefer. 

I'm doing a lot of promotion in the Miami area of my listings so I'm compiling a list of buyers.

BP has done such a great job of promoting SFR investing to the masses, that those masses have pushed up real estate prices to where it's now DIFFICULT to cashflow right away.Keep going, but understand you won't get rich in real estate overnight - it's a long-term wealth building strategy.For the short-term, recommend joining a few in-person investor meetings if possible, otherwise online ones.

Aloha @Daniel Kam - most of Kakaako has a 180 day rental minimum, so if you haven't checked with your building association, I recommend you verify what the minimum rental period is for your building.If you are allowed to rent for less than 180 days, you will then need to apply for a GET license, and well as TAT/OTAT and pay the appropriate taxes on a regular basis.
