Even if you didn't make a ton on the flip you are gaining appreciation on your personal home, just a though and best of luck to you!

I'm still a bit of a novice when it comes to wholesaling, simply because I haven't had many deals to gain the experience.

That allowed me to dodge being punished by capital gains tax and walk away with a nice amount to play with.  

I'm currently in High school, and  have  been gaining knowledge about the real estate industry.

Granted, it might be slightly difficult to gain access via an agent as their assistant unless they know you already.

I operate in the Lehigh Valley as a landlord and am acquiring additional properties, to flip and to hold.A natural way for you to get started might be to gain control, if not ownership, of some off-campus  student housing.

After gaining several years of experience, i discovered my passion and talent for real estate and decided to purse my own venture.

Try to find an experienced investor or two who'll allow you to velcro yourself to them to gain working knowledge.

The best I could do for a new agent was to just give them one of my properties to list ( at a reduced fee) to gain experience doing the real thing. the bigger companies have the focus on training and that is what most need in the first year.  

I have struggled with the sell vs refi question myself ... while I don't have a specific answer to your specific question, here is how I decided: 1)after the refi, will it cashflow with ALL expenses inluded ... if no, sell; 2)If yes to #1, take the sales price you'd get and subtract out the transaction fees to sell (capital gains taxes, RE commissions, etc) ... now, with that adjusted number in hand, ask yourself and answer honestly: If a similar house came on the market tomorrow at that price in that neighborhood would I buy it?
