Blind purchase of a duplex

[Tom Server]

Would you ever put an offer on a property with out looking at it if it cashed flowed $1400 a months ? 

Here is the situation, the property would cash flow about 1400 a month.. tenants are not letting anyone view the property. I was thinking of putting in an offer since it cash flows,(low offer) and during attorney review allow my self an out with any bad findings of the home inspection or the tenants records of payments not caught up ?  I know I'm taking a gamble of with ordering a home inspection and then tenants not opening doors.. but i feel tenants are probably annoyed with different people coming to see their homes.. but if planning a few weeks notice to let them know of a home owner inspection.. they might cooperate ?  Thoughts?
