I'm in a beach area where Sat to Sat rentals have been traditional for 100 years, but not any longer since the rise of Airbnb (and less control by local property management companies).

I never give the system or the prepped documents.

If you want to grow, then scaling within control is good.

At every foreclosure auction you will find the same cast of characters who know the system.

It was a good learning experience, but it made me realize that staying away from major rehabs (for now) might be the best move until I have a more reliable system in place.That said, having family in the area like your sister and brother-in-law is a huge advantage!

I've been here since the beginning, or real close to, and am happy to help you navigate and learn the site.As for where to invest, it depends on your goals, your tolerance for risk, and how much control you want.  

This implies residential units can be built at lower costs and provide better return. 11) adding an ADU to SFH can make the SFH fall under rent control.

Before becoming a designer, I was a systems engineer and business analyst (MIS degree), so my process is deeply rooted in formulas to keep the right elements at the forefront.
