It was surprisingly easy.My major challenge is that I have been managing major rehabs from half-way across the world.

I might be bias :), but I think Portland metro area is still a good place to invest on the west coast, much cheaper relative to other major west coast cities like SF, LA and Seattle. especially for appreciation, but harder if you are going for cash flow.

There are a few other major items but if I listed those someone might steal my idea, and I wouldn't want that.  

But after hearing multiple seasoned investors recommend not buying a rental unless you can afford to own it outright, or have major reserves to cover long vacancies and unexpected repairs, we decided to start with wholesaling instead.  

The majority of SFH investors are smaller mom and pop operations.

Then look at the cost of some of the major repairs that may need to be performed. 55% is a good Estimate but you'll want to look at all the real data before making a hard comparison.

Why is Denver immune to what every major city has displayed?

When I am looking at buying a single family home, I focus on major capex.

Percentages are great (Im a math major), but what really matters is a nice big check for your account plus the steak dinner!

Those are the two major players when trying to make an apples to apples comparison of debt vs no debt.A better question for what you are looking for would be: will an all cash purchase or a leveraged purchase yield a larger return?
