I started buying property about 10 years ago but have not been doing much since the crash of '09. 

Was this before the crash in '08?

I bought my first property at the beginning of the housing crash.

But im only 34I've looked at old posts and before the crash 7-8 percent was considered a good interest rate on investment property, now people are upset if it's over 5. ha

As you said, minimum credit scores dropping under 600 are definitely a warning sign.However, the lending environment is still much more conservative than it was during the bubble, and I believe that will act as a deterrent to a total crash.  

@Colin Clark Hello I was an active realtor back in 2004 until the crash in 2008.

Some would hold the money and wait for the Real Estate crash which will happen sooner or later and have cash to buy up a lot of property at discount prices.  

While i have never personally managed a property i did work at a company handling property management like tasks for a 186 unit development project while he was building it and got a great crash course while i was there.The main reason that I would like to do commercial is because having a rather large goal of 1000 rental units by the time that I am 40 years old which would be in 12 years from now. 

If you're a total newbie RE investor, I'd say it's a good way to get a crash course on the subject.

I keep hearing about a crash- should I wait for the crash in hopes that I can catch a good deal?
