I come from a tradition of apprenticeship where learning by doing has tremendous value.

Very fascinating...From a qualitative perspective, I think there is always that rite of passage even if you go straight into an apprenticeship, the time in which you must learn the craft, first, and yes you do get paid something, however minimal, during that time as an apprentice.

I  am currently looking to do apprenticeship for a real estate investor in the Dallas Tx area.

But by and large in my years in the industry most that make it work it for some company and put in an apprenticeship  ( just like a good carpenter they don't start out as journeymen)  then move up the chain or move out of the business.I also see investors games of just kind of using these people.. yes you go spend what little you have drive around find me a house.. make a small fee while I cash in.. and your only as good as the next deal you bring me.. if you don't bring me anything well sorry it did not workwhat ever this hype is about selling "how to"  to  people that see this as some great big profit generator when they have no money is just not reality. 

I’m really trying to find out where should I start to find apprenticeship in the Dallas Tx.

Offer summer/fall/spring apprenticeships to find quality applicants

really depends on what you want to do.. along the way the wash out rate for agents is above 50%.. and like I said wash out for wholesalers is about 90% but that 10% can make a nice living .. and morph into other areas.. usually they like to think they want to be landlords. oh and along the way I owned over 500 SFR's as rentals.. that my man is a ton of work and was very glad to sell out.. so lots of ways to use a brokers license along with some of the most successful brokers out there are Commerical brokers long apprenticeship but if you can stick it out its a 300 to 1mil a year income JOB and you are rubbing elbows with the very rich and very successful..  

He said that instead of chasing income, why not seek an apprenticeship to bird dog, build connections and learn how to be RE Investor.

I would love to add in a type of internship or apprenticeship a couple days a week.

Get yourself set up in one of the building trades with an apprentice ship.
