I have experience with cellular concrete in a commercial application as mass-backfill (15,000 cubic yards) for a newly constructed building where existing soil bearing pressures were poor.

If someone emailed me a list of 10 leads generated via SEO, I wouldn’t even look at them—not because there’s anything inherently wrong with them, they’re just not the type of folks I want to talk to. 

Condos are easy in my opinion.I'd say you aren't wrong in your line of thinking at all - Paying cash and getting cash flow right away is extremely less risky and could be the right move depending on your situation and risk tolerance.I think what most of us who commented above are thinking - is that one of the best things about real estate is being able to leverage OPM (other peoples money) and in this case, we are talking about leveraging the bank's money (and yours). 

But I'm wondering is it wrong to start buying rentals while not owning your primary residence?

@Ian Cruz, Nothing wrong with that scenario at all. 

@Daniel HanWhen asked about what could go wrong, I mention rents not being paid, poor underlying financials at the outset, unexpected expenses, to name a few. 

I have been a little shocked that about half of what I got is telling me I am wrong or that what I have already done is a waste of time. 

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

It seems steep and I wanted to make sure I am not doing anything wrong when I look at the taxes.

As previously mentioned, more recent laws seem to acknowledge this point.If that is the wrong characterization of the word "discrimination", what exactly would be the correct characterization?
