White male, so this is 100% opinion/expierence. I'd like to think I've helped a but over the years, but what do I know?

My advice, move into primarily black communities. Don't talk shit right out the gate, spend time to get to know your neighbors, you're going to expierence some distrust at first. Expect to be judged by the color of your skin.

Spend locally, hire the local kids to mow your lawn, buy from garage sales etc, get to know what's normal and what isn't, don't necessarily call the damn cops if your neighbours get into an argument. You aren't somehow better than your neighbours, don't act like it.

Don't gentrify the area. Understand that your neighbours are generally happy where they are, happy with the lack of HOA, might be a broke down car here and there, life is much more laid back, don't bring your "going to raise the value of this neighborhood" attitude with you.

Basically, take the lead in diversifying the neighborhoods, but don't buy up every house on the street to flip it out of reach of anyone working locally. The culture is a bit different, you'll find entire families living within a few blocks of eachother, bbqs every weekend and with a little luck you'll be invited soon enough, won't be long before you're part of the family too!

TL;DR Stop moving into expensive ass gentrified neighborhoods and justifying their expensive ass prices. Step out of your comfort zone a bit, you'll like what you find.
