They the turn their aggregated income all on paying off one property, get it done, and then move all their augmented aggregated income to the next property, get that done, and rapidly snowball all the money to paying everything off.There are all too many others, however, who base their business model on perpetual growth, think their spreadsheets are magic and will always work out month after month, smugly believe they've calculated for every possible manifestation of Murphy's Law that could hurt them, and just keep on acquiring and acquiring (and inflating and inflating their lifestyles) until something breaks their positive cash flow prediction model for a month or six and they go swirling down the toilet to a bankruptcy they never saw coming.When you owe someone money and you've committed to paying them over a schedule, there are always risks.

@Gus Muller I bought a house in Coon Rapids in February and ran into the same issues and had to replace the sidewalks as well. 

The house is an attached SFR. 2 Bed 2 Bath. 1380 sq/ft in San Clemente, California less than 2 miles from the beach in a rapidly appreciating area.

Yes, the concern is that foreign (far east) investors have been parking cash in Vancouver real estate and have left units vacant thus contributing to a shortage of housing that has caused rents to rise very rapidly.

Month to month has been nice in areas where rent is rapidly increasing.

Unfortunately, where I live the people's mindset is not similar to mine and I want to move somewhere where it is growing rapidly and there are plenty of opportunities.

Additionally you can rapidly redeploy your capital to provide different returns, say instead of income you think there will be a bull market so you move to capital appreciation securities to take advantage.

It is probable that even the prudent, more cautious investors are going to have plenty of time to make their move, because the conditions that are currently making moving overseas a more viable and intelligent option have both a fast and a slow evolution. ...and those factors are here to stay.

How secure do you really feel when a "serious" candidate for President from one of our two major parties either does NOT believe in evolution, or worse, isn't sure if he believes.Right now I'm actively working to defeat any Republican I can find.

I am assuming it snowballed as you generated more income and could reinvest that buying more rapidly.
