There are monthly mortgage, taxes, HOA dues and insurance expenses each month, however this still generates great cash flow every month.

I highly recommend you study this, practice it, and apply it.https://www.biggerpockets.com/blog/rental-property-cash-flow...Property Details:Type: Single-family homePurchase Price: $289,900Down Payment: 20% ($57,980)Loan Amount: $231,920Interest Rate: 6.85%Loan Term: 30 yearsMonthly Mortgage Payment:Using a mortgage calculator, your principal and interest will cost $1,515 per monthRental Income:Average Rent for Single-Family Home: $2,171 per monthOperating Expenses:Property Taxes: $300 per monthInsurance: $100 per monthMaintenance and Repairs: Budgeting 5% of rental income ($109 per month)Vacancy Rate: Assuming 5% vacancy ($109 per month)Property Management Fees: If outsourced, typically 10% of rental income ($217 per month)Total Monthly Expenses:Operating Expenses: $835Mortgage Payment: $1,515Total Expenses: $2,350Net Monthly Cash Flow:Rental Income: $2,171Total Expenses: $2,350Net Cash Flow: -$179 per monthConclusion:In this scenario, the rental income of $2,171 per month does not fully cover the total monthly expenses of $2,350, resulting in a negative cash flow of $179.

Quote from @Stuart Udis: @Robert Ellis In order for the QOZ investor to reap the tax benefits the hold period has to be longer.

Foreclosures force the owner to sell because missed payments, probate forces heirs to sell a family members home, liens ultimately force a person to sell there homes to pay what they owe in tax/fines etc.

Your not correct under many different circumstances.First property tax is 1.1% (fairly safe) with 2% annual increase (prop 13).Next expenses include a lot more than property tax and interest. 

Real estate has so many tax benefits and credits available, that I always tell people it's crucial to have a CPA that's extremely knowledgeable in this area.

Raise fees on building permits, give tax credits on renovations.Suburban sprawl really hasn't been a good thing for the US.Of course, it's all about supply & demand.But, if you can figure out why more people want to live in Hazel Park (leading to teardowns & rebuilds) versus south Warren or Eastpointe (nothing happening) then you can make millions.

Is taxes going to be higher today or higher in the future? 

 WE  do both  give me a call and I can explain but depends on where the tax advantage is

Otherwise they would have sold, taken the tax free cash and moved on.
