Having said that, there are two ends of a pretty wide spectrum of philosophy on this subject. 

Charlotte suburbs have been red-hot pretty much since the 90s (with the brief exception of the nation-wide downturn).In my opinion, the "investor-havens" like Belmont, Kannapolis, parts of Union County, Rock Hill are a little over-rated.

I was thinking more for a single family so it would definitely be a good idea to get a quote on it beforehand due to the wide range of how much it could actually cost.

I think you are going to get a wide range of opinions here because ultimately where and how you choose to live/invest can be a very personal decision and vary based on personal values, desired lifestyle, investment strategy, etc.

In a high demand area, there's not a ton of turnover and you don't need to advertise as widely.  

My current primary has a 30'' wide back door **hint hint** that's not a common size.

That is a wide subject where you agree to make payments directly to the seller and they agree to act like the bank and take monthly payments for their equity.

I am taking a sledgehammer to it tomorrow to make room for a brand new single wide mobile home I just bought for $32,000 bringing my total investment to $35,000.

During the world wide pandemic consumers spent $30B on entertainment which is a 20% increase from 2019.
