I believe you should concentrate on becoming a successful, experienced dentist before learning another trade (successful, autonomous investing).

I live in Philly and have used home advisor quite a bit for various trades. 

However, I don't want to trade a $45,000 loan for a $70,000 loan. 

@Evan Bellingar  real estate tends to go in 10 year cycles 5 is a little tight.but no one save a few ( watch movie big short) really saw the 08 melt down coming or thought it would be such a global disaster as it was....Were ORegon got hurt the most was in Construction... in from 1992 to 2007 there were an average of 12,000 doors being built in the metro area. that slowed in 08 and by 09 there was a grand total of 700 permits pulled... construction financing had froze .. and a great many in the trades went bankrupt lost their homes and are just now pulling out..

I know Karen Margrave does everything, but I think she subs some trades also.

Everything has a trade off in this business.

If I wanted something completely passive I'd probably skip syndication and move right into a publicly-traded REIT. 

The trade off of them taking the "risk" to refinance you within 6 months is the rates, terms, etc. will not be as favorable as a traditional lender.

If you're trading 8% cash-on-cash for 10% cash-on-cash I guarantee you'll blow that 2% marginal gain in travel costs.That said, those costs do get easier with scale. 

Can cover all trades and specialties. 15-30-45 day flips!
