@Bryce Nurding it sounds like you have a solid plan. 

.⚾ Franklin Yards-Gastonia- A $26M, 5,000-seat multi-purpose sports and entertainment venue, with future plans for residential, retail, and office spaces.🍽 Food Hall-Gastonia-Gaston County’s first food hall is in the works!

You will find that that was Biden's plan.

Just a simple 499 sq ft city approved plan, single story, 1 bed/1bath/full kitchen adu with living space.

Given that the seller is financing the deal for the 2 years and then the plan is to re-finance it with a bank, I am having difficulty producing such financial analysis.

If you plan to grow your portfolio, consider setting up separate LLCs for each property to shield them from liabilities tied to others, though this adds complexity and costs. 

There's other items such as this where it may be helpful to talk to a CPA/EA for a little tax planning, especially since you'll likely get caught up in the passive activity loss limitations if taking bonus on a single rental property as I often see.It's also useful to mention that even if you do the cost seg study (I'm assuming you're doing one to be talking about this), you'll still benefit from accelerated depreciation in the form of shorter useful lives on the assets where you received bonus from.

I have 2 properties i'm planning to purchase and wonder how is the crime and rental market in there. your response is much appreciated

Step 3: Compare build plans / specs to decide what you want to build.

My plan moving forward is to acquire another 20 doors before years end and I'll provide another Portfolio update around then.Happy Investing!
