Buying at full market value with 18% cap rate, will you do it?

[Jacklyn P.]

Hello. I am a newbie and I have been looking for deals. I read that as an investor, I should make my money at the buy which is getting 70% of the market value of the house minus the repairs. I found a landlord that wants to sell her rental at full market value. If I buy it at full price, it will make at least 18% cap rate. Should I buy at full market price if it has good cap rate?

Post all numbers. Also, I'd like to hear from anybody buying properties at 70% of market value right now as well. What are those, preforeclosures? I almost feel like there should be a new website opened called BP 2.0, for what it's now like well past the 2008 housing market disaster.
