You are right , lot of variables and a very difficult comparison, thanks for the tip, will search the forum 

It is a get rich slower scheme, but with less risk.How do you figure a paid-off property throws off more cash (per month, yes, but in comparison to how much you put down?)

Well, it is a simple comparison that makes sense.

You can even use a really fine-grit sandpaper.This video demonstrates how she repairs a stainless steel sink and it includes before/after images for comparison at the end.

I personally think that the right comparison is against the later example, since the cash flows are similar in each period.

And the housing stock in Miami is older and so much more expensive for what you get in comparison to new construction in Cape Coral.

But that is often an "apples to oranges" comparison unless you're going to live in the property/house hack.Got it.

Remember that comparison is the thief of joy - maybe they buy in very rough areas.

I would suggest maybe seeking the assistance of a real estate salesperson who could give you accurate market comparisons for the area, add to the description, and most importantly, take photos that will better highlight your property. 

Personally speaking, from an investment broker and investor standpoint, I feel single family investing is the riskiest in some investment ways in comparison to larger investments due to the fact that it only takes 1 repair or tax/insurance hike to put you under or lose all income.
