My original goal six years ago was to supplement my W2 earned income, and then to replace my W2 earned income, now it is to 10X that!!!!

@Roger Hefner  I tell fellow Veteran friends to look into becoming a landlord to supplement their income.

Retirement: Pension, supplement for social security until age 62 (then social security), TSP (401k), Vanguard Roth IRA, Vanguard Brokerage account, and rental property income.

Some of the metrics that I find valuable to understand are:- Population Total- Population Age- Home Values- Household Incomes- Rental Vacancy Rate- Homeowner Vacancy Rate- Poverty Rate- Educational Attainment Rate (High School/GED & Bachelors)- Number of Housing Unit- Rent to Income Ratio- Rent to Price Ratio- Population on SNAPS (supplemental nutrition assistance program) percentage- Property Tax Rate- Median Age of Buildings- Number of Structures by Units (SFR, Duplex, Triplex, Quadplex, etc...)- Median Rents by Number of Bedrooms- Unemployment Rate- Employment Sectors Percentages- Number of Building Permits Issued- Foreclosure Rate- School Ratings- Crime StatisticsWhen you consider all the variables listed above you will be better able to judge a locations tenant quality.Also take into consideration the direction in which each of these market indicators are trending.

To supplement my income in retirement, which, God willing, will be in 6 years.

Barista FIRE: quit W2 job, and work part-time to supplement all the investmentsFat FIRE: Living a pretty extravagant lifestyle (e.g. the social media gurus with their cars, traveling, etc).

I see myself slowly transitioning from full time rate race job in the next 5-10 years with real state supplementing other income.What are my next steps?

Yep, unless you need the money right now, for personal or investment needs, I'd keep the house.I'm in the same boat, but I'm on the other side, as I am now at the age of 50 getting my ducks in a row to supplement my income for retirement. 

If yes, flipping is a good plan if you are open to getting into some construction.Are you looking to just generate some cash flow to supplement your other income and maybe trade up properties every couple of years?

(Over $1,500 a month in extra cash from my four properties; and no I don't touch any of it as I am saving for more properties and my approaching retirement, so I will continue to go outside the great state of Texas.Small fish like me need to supplement their income and with a future pension on the horizon that will annually reduce in spending power with inflation, I can't afford low cash flow and bank on a speculated ROI 10 years down the road.
