Next let’s talk about their shady business practices.

Is there a best-practice on how to do this or can you share pointers from experience?

Very practical.

Only difference I see with my practice is outsourcing more services.   

Condos are starting to get condemned, which means people are having to vacate units.I'm telling you right now, I'm a JD (not a practicing attorney) in Florida whose business is being an insurance expert for carriers, working with engineers. 

Standard real estate practices.

Those seem like questionable practices to me.Great stuff from your own experience here.

Starting with single-family homes and growing a portfolio one step at a time seems like a practical approach.

Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

The example that comes to mind are often are of folks that operated a dental practice, an accounting office, a bankruptcy lawyer and her staff that did quite well in the 2008 aftermath, and so on, during those first few years, taking up a portion of or all of the space.Once you realize what a dumpster fire it is finding good financing for offices, if you need it, I'll be available.
