Investing: Is the current prices to high?

[William Huston]

I would still classify myself as a newbie in the real estate investing world, i have 3 rentals currently, but they all came from my military days as personal owned homes that i kept and turned into rentals, i had 7 rentals at one point, but i sold off the non-performing properties as soon as i could break even on them. The last few months i have been looking into another property to buy as a rental, but i feel like the prices around me are just way overpriced to make a buck. Seems like every deal i come across when i run the numbers the property is barely breaking even if i purchase and turn into rental. 

Just curious what others think on this as of lately, seems like the prices are climbing at the rate of pre-2007 did..
