Rates are going up and the hawks at the fed are starting to beat back the doves after about 6 years of post-crash loosening monetary policy. 

Most people got burned in the market crash, me included, because they were gambling with market appreciation.  

I started buying right after the crash and haven't had to experience the headache of trying to rent my property in a down market.  

I did own a few Residential construction company's one by myself and the other with a partner because of licensing.The crash of 08 hurt my business and i was helping keep it afloat with my income from my other job.

Before the last crash that it became harder to rent properties.

I have had so many unpleasant experiences with them that I just tend to keep to cheques, bank transfers and cash purchases at this point. 

@Caleb Heimsoth Thanx for the response,  put down 100k in 2008 right before the crash.

Vegas hit highs in 2006 that were about 200% more than 5 years before just like Phoenix and then crashed hard.

If the market crashes, you could lose your option fee because you can't find a buyer, or maybe if you misjudge the house's value and you can't sell it for a profit, you have that worry.

It the larger markets all over the US prices have risen back to and past the pre crash 2007 peak in prices.
