Listening to an older podcast, around the 250's number, Josh mentioned being able to post for free in the classified section here on Bigger Pockets. 

Also note that loan down payment, which I classify as anything less than 20% will have a mortgage insurance premium or Private mortgage insurance which affects cash flow and may take up to ten years to come off.Also, in residential property depending on if it’s a deed state or mortgage state(Check local laws) will require a human being and not a corporate entity to be on title and on the mortgage.If you really want to get your assets into corporate entities you can buy 4+ units which now becomes commercial or you can pay off your mortgage completely and then transfer to a corporate entity.Hope this helps.

Here is what you need to be able to classify yourself as a Real Estate Professional.Note: I have 20 rental houses, rehab and flip houses have a Vrbo Lake house that I manage and I am can't classify myself as a Real Estate Professional because I have a day job.According to the IRS, to qualify for REPS you must meet both of the following conditions:More than one-half of the personal services you performed in all trades or businesses during the tax year were performed in real property trades or businesses in which you materially participated.

@Fred Thomas sorry to be clear, this is classified as a vacation rental / second home, not non/owner/occ investment.

If you are just turning and releasing the unit after a tenant moves out, I would classify this as OpEx (turnover expense, or make lease ready expense).

Would these be classified separately as "start-up" expenses? 

If you are targeting Utah, KSL.com is an anomaly classified site that far outpaces Craigslist (also good) locally. 

My Dilemma: First, I understand this would normally be seen as "inventory," I was wondering if there's any way to classify this as capital gains?
