Remotely investing, flip or hold?

[Wen Guo]

Hello all, I have been looking around for a good market to tap in but I don't see I'll invest anywhere within my driving distance, as the number doesn't make sense. So if I want to invest remotely, for example in Dallas (while I'm in California), should I do flips and fly down occasionally to watch over the contractors, or should I buy and hold multi units with property manager? What do you recommend?
