Overall great macroeconomics great for investment - there's the booming tech scene, rapid growth in population and the job market, strong rental demand, and landlord-friendly laws.

But the neighbors told me when they built their house from ground 6 years ago, there was no issues for any building materials or trucks going through the alley. 3. the house is in historic district of Charlotte, meaning there are quite some restrictions on the exterior renovation. 

Basically every personal house we ever owned except this last one which we built from scratch.

I started in cheaper states and built up from there.

For example:"I deeply value the relationship we’ve built and appreciate the excellent service you’ve provided in the past.

There is a "hobbit house" that went on the market earlier this year that was built into a hillside.

The age of a home is sometimes a misnomer as older homes were built much better in many ways, not all.If you want to flip, you need to focus on older homes because that's where the bigger scale will be most likely and the more outdated cosmetically, the less likely first-time homebuyers will think they can do the work.

The only exceptions I can think of are a lack of experience frustrating your financing process or where the GC has such a well established brand that a buyer will pay a premium for a home built or renovated by that particular contractor.

Quote from @Jenni Utz: You have that built-in equity on the deals that are off-market.

Ponts can be built into your rate as well so compare notes with more than one lender/bank.
