Best is to speak to a local realtor .

Hey BP Fam,  I currently have a local investor looking to exit his rental business within the next 5 years because he's older in age.

I would join a local real estate investing club and figure out what members are actual investors and which are "going to be" investors.

Got myself connected with local agent, local property manager, and even learned some of the local politics during my visits.

As of this writing, 20 states and 106 localities have passed bans on discriminating against source of income (usually, but not limited to, Section 8) as well as a myriad of other restrictions.What Happened in Kansas CityKansas City, where I live, was the most recent to pass what its advocates call “the strongest source of income discrimination ban in the country.”

You can reach out to your local (state) Self Storage Association, peruse topics on You Tube, and certainly many, many forums here on Biggerpockets with quality folks & quality content.Regardless, of how you piece your learning together, everything (soup to nuts) for an Acquisition is either FINDING a lead, EVALUATING to determine if it's a deal, now you're in the PURCHASING phase, and after you close, now it's all about MANAGING.If you think that at times it makes more sense to build than to buy, then you'll want to learn about Development & Conversions.  

Was the ADU construction approved by the local agency?

Since you lack a local network, condos or townhouses with homeowner associations might be beneficial for easier management.

Hi @RonnieI would suggest utilizing the BiggerPockets local meetups tab to network and find out who is RSVP'ing to the events in Miami and targeting those specific individuals given you're out of state.
