There are sooo many factors that make one strategy more efficient than others.Plans for the home (minor touches, "to the studs", make it glamorous), condition of the home, its price in comparison to comps in the area, credit score, personal goals and fears (big factor), plans for children such as college, terms of the sale, trust in your inspector and your team, your workload, your current medical health, your stress tolerance, tax benefits, your family's stress tolerance, area's growth, your trust in the seller's disclosure, offers on the table, current interest rates...you get the idea.2) One of the most beautiful formulas (besides Euler's Identity) is:Interest = P (Principal) x R( Annual Rate %) x N (Time Period).

"Mortgage Broker (City name)" or "FHA lender" (city name) For investing & private lending, you use "Mom & Pop" bank, a local businessman who has extra money to lend, a doctor a dentist etc.

Other is College, medical, government town.  

If you do decide to go to College I'd suggest pursuing a career that requires you to go to college like Doctor, Lawyer, etc ...
