On the other hand, places like Whole Foods, Aldi's, and Trader Joe's are typically placed in better areas where residents have a higher median income than average.

I also try not to buy for appreciation because cash flow is what puts food on the table.

They give them food, shelter and a paying job.

Prices are higher for food, utilities, gasoline etc.5.

In my mind, that’s the biggest advantage of the real estate business vs other small business like a food truck or a barber shop. 

Food for thought though.

Furniture, food left overs, toys, clothing, appliances.4.- Getting rid of any infestation.

Those migrating from expensive cities such as New York, San Francisco, Seattle, etc will still probably desire all the amenities of a major city and seek to relocate to a smaller city that still has major sports teams, great food culture, transit options etc. 

A huge part of the population works in service industries and more than $750 a month is more than they can pay and still put food on the table. 

At $2k a month income, that barely will keep maintenance, insurance, and taxes on a house, a car gassed, insured and maintained, medicine/medical expenses, and food on the table.
