Looking at purchasing some vacant land in NC that has an existing lease on it to a 3rd party.  

Check that the information is accurate, then try again.There are many websites where individuals can purchase fake credit reports, pay stubs, letters of hire, etc. 

Purchase price: $95,000 Cash invested: $30,000 This was my first rehab.

This could provide funds for an EMD without needing a personal loan.Bridge loans - While not specifically for EMD, bridge loans are a short-term financing option that can help fund a purchase before you have access to longer-term financing or funds from selling another property4.

I use the Authentic Plank product from Southwind which is an 8mm thick plank and does not require an underlayment.

I'm trying to understand how the financing works; Let's say I get a mortgage on the property, but only own for 6 months, as I've purchased, renovated, and made the sale to the next owner.

Purchase price: $325,000 Cash invested: $5,000 Sale price: $389,900 This was a quick wholetail deal!

What side of town did you buy on and how many units was the property you purchased and what was the price?

Since the home is so new, the title is likely fine but you'll want to make sure you're aware of any liens on it (likely the case if its purchase was financed).An ADU is not a bad idea or even bring in another trailer if the county will let you.

A potential issue I will point out is that I’m pretty sure you need to put into service the property in the year you purchased it, at least for bonus depreciation.
