I’ve sold properties recently in heavily restrictive communities as they’ve began to tighten rules.

I’ll reply with an appraiser’s point of view- many times if something is permitted, an appraiser will require inspections, and if inspections turn up overall inferior work, they’ll either heavily discount the inferior square footage or not count it at all.

I was relying too heavily on only one contractor that had only done a few jobs for me.

There are many of my friends that I have been able to help them buy their first house, and even if you don't want to be a heavily involved agent, just helping your friends from school is a good way to get some cash to start saving capital.

I looked into it pretty heavily for electric bikes for one of my apartments.

We targeted C class properties that needed some work to get started.  3-4 years ago (when we were buying heavily) this took on average about $30,000 to close on a deal, and then we would spend maybe $5,000 polishing up the place (new carpet or tile), and maybe some new paint.Today it’s probably tougher to find that deal.  

I invest heavily in the Smoky Mountains.

As has been already mentioned, tax advantages heavily favor real estate investing.

I invest out of state but am heavily considering house hacking in OC for my next project.

"It works"... you simply can not quantify a system with "it works".OK OK OKI am going to go heavily against you but don't feel offended.
