@eric yes true.

This is especially true as you identify your target niche for investing (flip, wholesale, buy and hold, short term rental, etc). 

My instinct tells me its not true, he may using that as an excuse to kick them out.

True, but for CA this is fairly decent cash flow, if you want max cash flow you may look out of state instead.

Really talk to the home owner and see what the true problem is and if another option is better then I want to let them know.

Also include some sort of reply "STOP" to prevent all future texts and make sure you remove those numbers to avoid any possible charges for contacting someone on a do not call list.But that first deal better be awesome, It's true what they say about you only get one chance to make a first impression.

True you will know it the best but with such a limited tenant pool and probably limited potential for growth is it the best option?

I would ask some questions to make sure they are a TRUE TK Provider like:1) Do you own the Turnkeys you sell and not just list them2) Do you do IN-HOUSE management and NOT use a third-party?

Honestly this looks to good to be true based on the numbers. 

On the surface, and as Andy mentions, that's seems too good to be true, so there is likely some underlying factors not divulged.
