Ideally, I’d like to buy it, and fix/update both sides at the same time for ease on my end.

I'd like to gain experience in a mix of flipping and BRRRR locally (NC), at least a few each by end of this year.

Otherwise I’d suggest you sell and take the tax free gain.

Here are a few zip codes I'd recommend: 38122, 38125,38128, 38133, 38134, 38135, 38115, 38116, 38117, 38118, 38119, some of 38109.

If I'm wanting to lend money to someone with my private money, for them to purchase or refinance and I'd be recorded as the 1st position lender, would that money be a tax write off?

haha.To piggyback off @Jeremy Jareckyj, I'd check your local regulations to be sure this is allowed in your city/zoning.

I'd like to meet other physician investors and want to know how you overcame that 'truckload of money' mentality and decided to invest in real estate. 

That may sound pretty good...until you discover that their net worth is decreasing at a rate of $2 million per year, and they've got $100 mil of adjustable rate debt on a portfolio of D class properties that forces them to work 80+ hours per week just to keep the whole thing afloat...Investor B tells you "my net worth is $1 mil" --to many successful investors, that sounds like a relatively insignificant net worth...but, investor B owns a portfolio of A class properties with zero debt, professionally managed, their cashflow is $500k per year, their net worth is increasing at a rate of $1 mil per year, and they only have to work about 1-2 hours per week to keep their machine going.Personally, I'd MUCH rather be investor B than investor A, even though investor A's net worth is 10x of investor B's.So yeah, tracking net worth is advisable, but it's only a small part of what an investor should be tracking and modeling, and net worth alone might not be very indicative of an investor's success.

I'd love to hear from your experience. 

If it's a great deal - I'd say go for it.
