What Percent? real estate vs stock market, vs cash

[Account Closed]

Curious what others think good percentages are to be invested in real estate compared to the various investment vehicles such as stock market, peer to peer trading, etc. How are you chopping up your nest egg?

Personally I am over 80% real estate and am just wondering what is a good percentage. 

Also, how much do you keep in cash reserves per property for vacancy & maintenance? do you automatically portion out of each rent for future maintenance/specific account that just keeps getting bigger? seems like its easy to want/be tempted to just invest any large sums that you build up from these maintenance acct instead of truly keeping them liquid. I would say im a bit more on the conservative type, I personally wouldn't consider debt a form of reserves for maintenance.

What are your thoughts?
