I am wondering if the interior stairs are typically removed to allow for more sq ft in the basement unit as well as greater security  between the two units?

In particular, OO does not have vacancy or PM and typically has cheaper maintenance/cap ex than the landlord would experience.https://www.realtor.com/news/trends/its-now-officially-cheap...if you use realistic expenses, purchase at retail (off MLS) without a value add, you will have negative cash flow on virtually any purchase.  

I wanted to have a spot to rent out and cover the monthly mortgage payments while securing a small spot to have for myself in the next 30 years for when I no longer reside in Charlotte but want to visit friends, or downsize.

The information is typically - lease start and end date, how much rent is, what the security deposit is, and how much in advanced rent there is.

So this is common thought and why it is a real challenge to get debt secured by the ADU value add at higher than 50% of the addition cost. 

I do a lot of direct bookings that take security deposits, but with Airbnb, they are always tough.

Due to recent security frauds and banks not covering losses adequately, apps like Zelle may not currently be the best option.

Like you, I was eager to start investing in real estate but decided to hold off until I had more visa security.

First, request the current rent roll, which details each unit’s rental income, lease terms, and any security deposits.

Do you have to keep the security deposit in a separate account?
