Here in Metro Detroit the "ring cities" we have a solid mix of $80-$120k purchase price, 1-1.5% deals or so, $200-$350/door, 10-14% ROI, "Good investment areas".

It sounds like you are doing STRs in Florida, but if you are interested in them in this area, be aware there are really only three cities in the Denver area that allow short-term rentals in investment properties -- and each of those three differ in how you can do it.

Because you are going to live in it I think his answer rings true.

When you rented to that tenant three years ago, a water heater may have costed $900 to replace and today it is $1100 (example only).

In fact, the last three rentals of mine that came up for renewal in the last year had new tenants apply, background checks completed, and first months rent + security deposit paid sight unseen.

Getting two-three rents in one building is ideal.  

All of these stories that they had built put them in a position to believe that this project was going to be successful so it's that dream home and here are all the reasons why it makes sense when you're making a business decision you can look at those things and that's nice and it's what you should do and you can even extrapolate you can come to me and say listen here's all the spreadsheets this is why this deal makes sense.And that's a good way to look at it, a business venture but what you must do is contemplate your worst-case scenario if the market corrects back if that asset falls from where it's worth six hundred thousand down to three hundred thousand and believe me no one will believe that can happen but I've seen it so it'll go from six to three.

I have come across several properties with more than one mortgage, one with as many as three.

I would view jobs as a temporary necessity to build up cash for investments, be they education investments, business investments, or real estate investments (and I wouldn't invest anywhere other than those three). 

These are the three rules of real estate investing.
